This does feel a tier up from homemade. But while I have a couple ideas how to make it using casual hobbyist hardware, there’s still the injection die issue - and I can’t think of any way to overcome it without a metal-capable CNC
@@Pentross Exactly, making the machine is the cheap and easy part in the long run, the cost and difficulty is in the dies and keeping them in good condition. Takes nothing away from this effort though, cool setup.
You guys have a good formula for youtube hits. Short and fun videos, showing the final product in use, and then a quick summary of how it was built. This coming from someone who has probably spent 100 hrs watching RUclips cnc build videos:)
HAHAH, thank you 😂. we really wanted to focus on keeping it short and entertaining in order to help people watch the entire video. we didn't want to make this a 2 hour documentation. Glad you enjoyed.
@@ActionBOX I think the split YT channel thing is a good idea. One for short videos showcasing the final product (with monetization) and one for long builds and details.
If you upgrade this machine or design a new one, you should consider moving from a piston to a screw to generate the injection pressure. Plastics are shear thinning, meaning that they become less viscous under shear (like in screws). This is caused by the polymer chains becoming less tangled, allowing them to flow more easily. You will be able to inject at a lower temperature and pressure, leading to less polymer degradation and mold wear. Thinned polymers will also weld to themselves more readily, so if you move to molds where the flow splits and re-joins itself (like in a ring-shaped mold) the parts where it re-joins will form stronger joints.
@@ActionBOX Unfortunately, you need a pretty big motor to keep up with that kind of flow rate. I looked up the specs on a run-of-the-mill commercial machine and it has a 7.5 kw motor for a shot size (amount of injected plastic) of 55 grams. For the kind of unit you would be able to build at home, you will have to keep the shot size pretty small.
@@eric8syj1 Hi! What is the best type of injection moulding machine? With your comment you imply that machines that push the polymer mass with a plunger are not optimal. Thank you.
Thanks, Thats the plan, I just need more viewers as it is not worth all the efforts for me to clean up the files and make a new more detailed video for such small interest. Feel free to share this video with any groups you know who may be interested. Im glad you enjoyed and thank you for the awesome comment 😃
@@ActionBOX think it works the other way round.. make more detailed Vids with links to the project build and you get more viewers... "DIY perks" now making a killing .. hope you get there these are some high quality projects hope you get to open source them
Having work for many years in a injection molding plant: you pretty much got a basic entry point perfect. 5 years ago when I was Trying to make a run of about a hundred parts I happen to look at the pricing on the most basic injection molding stuff... I'll just say I sure wish I had a easy do-it-yourself kind of mold machine like the one that you guys created
Cool machine! I am a Controls Engineer and I primarily do controls on rubber injection presses (hydraulic motion control). I would love to see how you guys did the logic on a raspberry pi. I used to run my machines with Rockwell Automation controls (ladder logic), but have since switched to B&R Automation (primarily structured text). Lots of advantages over the former. So many similarities between the two types of injection machines, so I really enjoyed this video! Keep up the awesome work, I am subbed for life now!
I'm not sure if you're still using this injection molding press for production parts, but you can get shorter cycle times and better tooling life by circulation of cold water through the mold. It's pretty simple to add water lines to the molds. I used to be an injection press tech and a CNC programmer/machinist making primarily injection and blow molds. Your design is very close to industrial presses, any larger than this and you will want to go to hydraulic clamping, though. The nozzle forces are insanely high with injection molding.
Can you please make longer in-depth videos explaining everything that your doing and the parts that you are using especially for the cnc router and mill. Also love your videos.
It takes a long time to do so, but if I get a great interest (aka over 100k views) then I will make an in-depth video, and also provide my CAD designs and Bill of Materials, and all my suppliers for each part. Feel free to share my videos with anyone who is interested if you liked them 😃. Cheers

Mate, i don't need build plans or anything - i can make a design of my own, but the thing you give away in massive quantities is motivation and inspiration to get of my lazy a$s and make something! Thank you! All your builds are great! I wish you all the success and more
Love the design, the small scale stuff is great for hobbyists and small businesses too. A small CNC to make your own moulds, then a small injection machine to make them
Many years ago I used to do some support for these types of machines. The companies specialty of CD cases. As you are attempting to have an automated system, you need to control the temperature of the molds. We had heater coils on the molds to get them up to temp so the plastic would flow. After running them a while the mold gets too hot and the molded piece will not eject, it will just tear. We had water lines cut in the mold that circulated. We monitored the temp of the mold to tell if we needed to heat the mold or cool the water. I know it may be beyond the scope of your build, but next time!! :-)
As i know, injection mould nornally made by professional (and expensive) cnc that achieve high tolerance (mirror like surface finish, you guys probably will achieve this quality in the future i believe) Is there any significant difference between your mould and “professional” one. You guys are gonna be the youtube star for sure

Next step: Build a CNC Laser or plasma cutter to churn out some sheet steel parts for an enclosure, then build a brakepress to fold all the sheet parts, and build an enclosure.. this machine deserves a nice enclosure!..
@@ActionBOX ah.. well.. same here.. i built my own CNC mill (4 axis.. 5th axis yet to build), i converted an EMCO Compact 5 CNC to EdingCNC, i still have to really finish it, and put it in an enclosure, I have a Wire EDM, and a Sinker EDM that also need some TLC, and an EMCOturn 120 lathe that i also want to convert to EdingCNC, and add some features like automatic chuck, barfeeder and parts catcher..
It's nice to have the support of a professional in the field. If you know of any groups or forums that would be interested in this, feel free to help me out and share. Cheers 😃
@@ActionBOX Hahaha. I don't think I qualify as a professional. On Semi-Auto I just open a door pull the runner out and the part out (or just the part if the part has a sprue) and close the door. On fully automatic cycles like yours was running, the machine drops everything into the chute and the mold closes. Some of the presses at the factory I work at are absolutely massive. I am not a technician and I am not able to actually work on the machines. Either way. I am thoroughly impressed. Be careful however of the fumes when purging your machine. Our big professionally made machines have warnings about inhaling the fumes of molten plastic. I'd assume that it could be just as dangerous for your little mini-press
@@Mboy245 Thanks Jonathan. Just being exposed to these machines already makes you an expert 😜. It actually teaches you a lot. Believe it or not, I've never actually seen a real machine in person (up close). Just read lots about the physics at play. The fumes are definitely a point of concern, Great Point.
@@ActionBOX currently designing an open wheel racing chassis! (F1/indicar) mostly going to be composite's. in the process of doing the CFD modeling for certain parts! you can see a brief animation I did for a client for their rear wing/spoiler!
This is super cool. Any chance you could go over the BOM and costs associated with all of your builds? I'm interested in everything you've done so far. I'm sure this channel is going to blow up in no time!
It’s a reciprocating screw and we sell them. I can send you a picture if you would like, but it’s a conventional tapered plastic injection screw (a reciprocating screw). Price per screw and barrel is $900 shipped.
Thats true 😂, although, with enough thought anything can work out. Im glad you liked the video 😃. Don't forget to share with at least one friend, it would help me out
How do you guys only have 15k subscribers?! This reminds me of minecraft, where you make the thing to get more resources to make the next thing. Only you guys are doing it with mechanical, electrical, and electronics engineering. You guys rock - keep it up!
Thank you so much 😃. We do love building things for the purpose of building more things 😅, and we have only been at it for a few months now, so we are happy with 15k subs. Working hard to make more content. Glad you are enjoying so far 😁. Dave
@@ActionBOX thanks for the response. So some moulds require a higher pressure to fill the mold. How would you do this with the machine? Likewise some may need less pressure to reduce flashing Great content by the way
@@3dfabrication Our max pressure is limited by the motor power. If we want more pressure we would just move the motors forward a tiny bit. Aka we tell the machine to fill the motor an extra 0.1ml. Does that make sense? I know it’s not as ideal as real machines but it’s the best we could do for a tiny machine like this.
Thanks so much. Feel free to reach out if you ever need help. I always try to respond. Don’t forget to share with a friend or two 😃. It would help me out.
Your content is fascinating, yet the main premise of the interest that brings people here and causes the views is we wanna learn how to build such machines. I really hope you keep producing these videos in a more detalied fashion Also, for improvement ideas, what causes the problems in some of the plastic parts lined up at the end? It looks like something pushed into the plastic
Hey, I appreciate this comment. This machine was the first I posted on RUclips, so I wasn’t familiar with the process of filming. If you check out my latest EDM sinker and EDM machines, I hope you would find far more details as per your request, plus better production quality. Cheers, Dave
I was wondering about the final parts as well. Only the ones closet to the camera looked to be a really good part. I take it you guys know the issue, would be interested in hearing what was the issue.
@@philsarcade the spot on those molded parts looks like the outlet for excess plastic, when the mold is filled there should be a little extra squeezing out that you will trim off after the part cools.
Does this machine have an additional compression routine after injection? Nice build, I always dream of having an injection machine at home for some car parts. Build it for myself and like minded people all over the world.
At the end of the injection cycle the machine will hold the pressure, although now that you mention it, I could benefit from adding to the code a step in which the motors inject just a tiny bit more (say 2% of total injection size) to really drive up the pressure. Cheers, Dave
Hi, great question, I don’t have an exact answer right now, but when I go over the build in a subsequent video I will add all this information for you. Cheers, Dave
What is inside the heating tube to pump the plastic? An auger? What happens when the remaining unused plastic cools inside the machine? It can be re-melted and not gum up everything?
I want to add something u can keep ur tailstock platen moving not clamped to base this will give u adequate tonnage if u want higher injection speed and pressure. Just a suggestion. Can u make tutorial on raspberry programing
@@ActionBOX I have done training in injection molding manufacturers . That machines where much bigger and fully hydraulic. What I mean to say is there are three plates in clamp side one which is on injection side, 2 is moving one and 3 is where mechanism for moving 2nd plate is located. So u have to keep 3 plate which hold mechanism to be free from base not fixed.
@@ActionBOX also by keeping it free when ur moving plate touches the 1st plate and if further movement is applied the lead screw will act as tie bar and streches which will indeed add more tonnage force
Everything is cool. The only thing I would change is injection port and pushing rods for the plastic product should be on same side. This would make sure all flows are inside the box and you can not see them
Great question, it’s slightly wasteful as you need to run the new plastic continuously until the system cleans the old plastic. Takes around 9 minutes.
Yes this can go bigger cheaply, but would then begin to require 3 phase power which most people don't have at home. If this is for a shop then its definitely possible.
Most of the money was spend on research and development. The machine itself can be made for several thousand dollars. I do not have the exact cost on hand, but when I build another one I will come back and let you all know. Thanks for all your support. Do me a favor and share the video if you liked it. Cheers, Dave 😃
this is fantastic! As an electronics guy with minimal mechanical knowledge, I'd *love* full design and partslist info if you ever decide to make it available... because I could really use a small injection molding machine like this. Anyway I've subscribed and belled you, and looking forward to watching all your stuff in the meantime.
Thats awesome! with enough interest I will definitely share the designs and make a more detailed video. Its just very time consuming so unless there is substantially more interest it is not worth my time. Feel free to help me out and share this in groups that may be interested 😃. Glad you enjoyed the video.
@@ActionBOX you're really good, I have no doubt you're going to get a lot bigger. But I'll do my bit to promote if it gets a design pack for building this project quicker. :-)
This is amazing. I’d love to collab anytime you would. Certainly a type of machine I’d like to help contribute to bring to open source. Keep up the great work. Subs will come in time.
It's perfect project. I've been thinking about it for 2 years. I would appreciate if you share information where did you buy or maybe you mill the screw for injection. Basically I stuck on it.
Thank you very much! I will be posting a second video detailing all the specifications. In the meanwhile, feel free to help me out and share with one friend or group who would be interested 😃
I bought a nice electric log splitter with the intention of using that as a base for a injection mold machine. Had to sell it along with most of my stuff in order to move across the USA. I want to get stared and build it now but so many projects. Maybe in another yr or two. The log splitter was 8 ton, or 16k lbs. I have studied DIY injection mold machines built by others for a long time and one thing is pretty constant, they do not have enough clamping pressure. I do like his machine but I would combine this with a simple hydraulic system for much more clamping pressure. Might just buy an industrial model with 50 ton clamp system. Those are pretty cheap to buy but parts cost will kill you, specially the electronics. Mine will not be fully automated, I do no think I can come close to these guys skill on that level.
Hi, great project!! How does the plastic stay in the injection chamber while it is being filled by the screw? Does it not come out of the injection chamber nozzle as the plunger retracts? Is there some kind of "closing valve" to prevent the plastic from flowing out the chamber while it is being filled?
Hi, Great question, there is a nozzle pressure valve, which is essentially a steel ball that is spring loaded. It only opens with sufficient pressure, such as that during injection. Otherwise, it seems against the steel body, so there is probably a theoretical leak, but it doe not affect function. Cheers
@@ActionBOX Got it. One last thing, what are the clamping force and injection pressure in this system? Seems to me that industrial machines are always oversized in terms of clamping forces. The one you build probably doesnt exceed 5 tons right?
Hi Leon! Thanks for the comment. We have quite a few projects going on, so we’re planning on making a longer detailed video about the plastic injection machine in the near future. Meanwhile, stay tuned for some really cool upcoming machine videos! Cheers, Alan
I’m not sure what you mean by leftover borders. Our parts come out as intended, with a break off tab that we cut off with cutters. Does that answer your question? Cheers
nice work bro, this is sick. just one recommendation to put the hmi on the same side the operator stands on. Most places would consider reaching across the machine to operate it a safety hazard, haha.
Yeah, there is the actual engineering (which was hard enough) and then the human factor engineering which was too much for a single student to handle 😂. Great point though, and thanks for watching in detail.
@@ActionBOX Please do, I've not seen anyone try this yet. I've been pondering on getting a cheap diy injection molding kit for this purpose and to learn some CNC skills for making aluminium molds, but it would be great to see if it works first, or if there are some issues. Recycling PLA scraps with this would do great for local communities, and would be far easier to setup than consistent filament extruders.
@@ActionBOX for small scale and light weight pieces (e.g. skirts and support structures) I've used just a kitchen blender to get the pretty small. Looking at your workshop, I guess you could have the resources to get or build a "Precious Plastic Shredder" or something similar. Basically a scaled up version of a office document/paper shredder, with beefier metal teeth.
Yes I will be in the future. Glad you enjoyed the video, and don't forget to help me out in the meanwhile by sharing with at least one friend 😃. Cheers, Dave
@@ActionBOX I will for sure. I´m in a moment in my life that I simply urge to have a small injection machine. But that steppers are very expensive here, I have two nema 34 from a previous project, and will try to get 2 more. Also, I will redesign using leadscrews. I hope it works somehow.

Thanks a bunch 🙏. There is something big coming in the future, but I am working on smaller side projects in the meanwhile to keep our channel alive. Cheers, Dave
I couldn't agree with toy more.lots of knowledge to have done this
yeah its hilarious to ask for donations from us over a short teaser video that doesnt really show us anything
This is awesome! I wonder if you ran some 40x80 aluminum water cooling blocks across the mold if they would have a better yield?
I will have to try. Great recommendation 😊
First time I enter this channel, wow, what a genius friend, I congratulate you, very entertaining and motivating, I really liked the video, your explanation and everything else, thumbs up and subscribed, I hope to see more videos like this, Greetings! !
I am just blown away by the brilliance of your work and have also subbed. Take a bow sir
Welcome aboard! Thank you for your support and compliment. Do you have any plans to build a similar machine?
@@ActionBOX I wish I could but I really don't have the skills. I had a project of mine injection moulded in China but would have liked to have done it myself. I also have another project in my head which was how I stumbled on your channel.
@@NatureVapeReviews Keep watching RUclips videos and you will learn 😉. RUclips seems to be a great substitute for other means of learning these days. I know you can get there if you want to. I did
Amazing work！ The small fixed screw arbor can be used to inject big weight plastic part. Can you make a short video to explain how the elbow is designed? Thank you
yes I will eventually, and Thank you very much for the compliment! f]Feel free to help me out and share with one friend or group who would be interested 😃
Next step: Build a CNC Laser or plasma cutter to churn out some sheet steel parts for an enclosure, then build a brakepress to fold all the sheet parts, and build an enclosure.. this machine deserves a nice enclosure!..
Hahahhaha, very true, I have thought about it 😜. Lots of machines left to build
@@ActionBOX ah.. well.. same here.. i built my own CNC mill (4 axis.. 5th axis yet to build), i converted an EMCO Compact 5 CNC to EdingCNC, i still have to really finish it, and put it in an enclosure, I have a Wire EDM, and a Sinker EDM that also need some TLC, and an EMCOturn 120 lathe that i also want to convert to EdingCNC, and add some features like automatic chuck, barfeeder and parts catcher..
@@JanBinnendijk sounds like its time to start working then 😂. Very cool.
I work with a full size plastic injection molding machine. Fascinating to see a homemade desktop version
It's nice to have the support of a professional in the field. If you know of any groups or forums that would be interested in this, feel free to help me out and share. Cheers 😃
@@ActionBOX Hahaha. I don't think I qualify as a professional. On Semi-Auto I just open a door pull the runner out and the part out (or just the part if the part has a sprue) and close the door. On fully automatic cycles like yours was running, the machine drops everything into the chute and the mold closes. Some of the presses at the factory I work at are absolutely massive. I am not a technician and I am not able to actually work on the machines. Either way. I am thoroughly impressed. Be careful however of the fumes when purging your machine. Our big professionally made machines have warnings about inhaling the fumes of molten plastic. I'd assume that it could be just as dangerous for your little mini-press
@@ActionBOX Also I shared your video with some of my coworkers. They thought it was pretty neat. Keep up the great work and cheers to you too 😎
@@Mboy245 Thanks Jonathan. Just being exposed to these machines already makes you an expert 😜. It actually teaches you a lot. Believe it or not, I've never actually seen a real machine in person (up close). Just read lots about the physics at play. The fumes are definitely a point of concern, Great Point.
@@Mboy245 I LOVE THAT. Thanks for sharing and helping my channel grow 😊. I look forward to your comments in my future videos
Nice to see more Canadian builders! Greetings from the capital region!
Right on 😃. What do you build?
@@ActionBOX currently designing an open wheel racing chassis! (F1/indicar) mostly going to be composite's.
in the process of doing the CFD modeling for certain parts! you can see a brief animation I did for a client for their rear wing/spoiler!
@@camofelix Thats is supper neat. where are these animations?
@@ActionBOX On my channel I meant! It's the only video currently set to public I believe!
DIY Autoclave next 😁
one day 😉
This is super cool. Any chance you could go over the BOM and costs associated with all of your builds? I'm interested in everything you've done so far. I'm sure this channel is going to blow up in no time!
Thank you 😊
this guys wants donations but wont even bother to make an actual build video. what a joke
Thx for reply..I see vid fine now..mayb 240p works better than 380p (or whichever)..good ingenuity😎
Thank you. Much appreciated. Any plans to build your own machine?
Injekto 2.0 can be used to inject plastic into a mini soldier figure (with high details and thin parts) 3d printed mold?
One word, wonderful machine.
Thank you 😊
Do you have a sectional view diagram of what the feed screw looks like. or where you sourced the screw itself?
It’s a reciprocating screw and we sell them. I can send you a picture if you would like, but it’s a conventional tapered plastic injection screw (a reciprocating screw). Price per screw and barrel is $900 shipped.
This is just incredible, imagine being that intelligent
Thanks Jason 😊 I appreciate hearing that.
Dave
badass... you took a leap of faith to buy all of that on a maybe... my hat's off to you.
Thats true 😂, although, with enough thought anything can work out. Im glad you liked the video 😃. Don't forget to share with at least one friend, it would help me out
How do you guys only have 15k subscribers?!
This reminds me of minecraft, where you make the thing to get more resources to make the next thing. Only you guys are doing it with mechanical, electrical, and electronics engineering. You guys rock - keep it up!
Thank you so much 😃. We do love building things for the purpose of building more things 😅, and we have only been at it for a few months now, so we are happy with 15k subs. Working hard to make more content. Glad you are enjoying so far 😁. Dave
Do you also build them by pre order?
Havnt considered it but I could try.
Awesome machine!! How do you vary the injection pressure? Is it through varying the current to the motors? Thanks
Hi mark, the pressure is not tightly regulated in this machine, but more so injection volume. Does that answer your question?
@@ActionBOX thanks for the response. So some moulds require a higher pressure to fill the mold. How would you do this with the machine? Likewise some may need less pressure to reduce flashing
Great content by the way
@@3dfabrication Our max pressure is limited by the motor power. If we want more pressure we would just move the motors forward a tiny bit. Aka we tell the machine to fill the motor an extra 0.1ml. Does that make sense? I know it’s not as ideal as real machines but it’s the best we could do for a tiny machine like this.
@@ActionBOX that makes sense. Thanks for letting me know
Holy. Crap. I can't even imagine where to start with this. Fantastic job!
Thanks so much. Feel free to reach out if you ever need help. I always try to respond. Don’t forget to share with a friend or two 😃. It would help me out.
How did you manage to avoid losing plastic from the nossle when loading with the screw?
What hardware and software you used to to make cnc
I also want to build with touch screen like you and auto adjust distance of injection and molds
Hi, we wrote our own software for this machine. Cheers.
@@ActionBOX tell me hardware what you used and sensor and components list
Your content is fascinating, yet the main premise of the interest that brings people here and causes the views is we wanna learn how to build such machines. I really hope you keep producing these videos in a more detalied fashion
Also, for improvement ideas, what causes the problems in some of the plastic parts lined up at the end? It looks like something pushed into the plastic
Hey, I appreciate this comment. This machine was the first I posted on RUclips, so I wasn’t familiar with the process of filming. If you check out my latest EDM sinker and EDM machines, I hope you would find far more details as per your request, plus better production quality. Cheers, Dave
I was wondering about the final parts as well. Only the ones closet to the camera looked to be a really good part. I take it you guys know the issue, would be interested in hearing what was the issue.
@@philsarcade the spot on those molded parts looks like the outlet for excess plastic, when the mold is filled there should be a little extra squeezing out that you will trim off after the part cools.
Does this machine have an additional compression routine after injection? Nice build, I always dream of having an injection machine at home for some car parts. Build it for myself and like minded people all over the world.
At the end of the injection cycle the machine will hold the pressure, although now that you mention it, I could benefit from adding to the code a step in which the motors inject just a tiny bit more (say 2% of total injection size) to really drive up the pressure. Cheers, Dave
Nice! Great use of technology. Will be looking for a company that can create small gears in volume after the prototype is complete.
That would be cool!
Nice job! What did it end up costing to build (ignoring labor/time)??
Hi, great question, I don’t have an exact answer right now, but when I go over the build in a subsequent video I will add all this information for you. Cheers, Dave
What is inside the heating tube to pump the plastic? An auger? What happens when the remaining unused plastic cools inside the machine? It can be re-melted and not gum up everything?
Special screw. I will show it in a future video. Cheers.
I want to add something u can keep ur tailstock platen moving not clamped to base this will give u adequate tonnage if u want higher injection speed and pressure. Just a suggestion. Can u make tutorial on raspberry programing
Can you elaborate on what you mean? I’m not sure I understand.
@@ActionBOX I have done training in injection molding manufacturers . That machines where much bigger and fully hydraulic.
What I mean to say is there are three plates in clamp side one which is on injection side, 2 is moving one and 3 is where mechanism for moving 2nd plate is located. So u have to keep 3 plate which hold mechanism to be free from base not fixed.
@@ActionBOX also by keeping it free when ur moving plate touches the 1st plate and if further movement is applied the lead screw will act as tie bar and streches which will indeed add more tonnage force
@@ActionBOX I am not sure it will work at small machine. But it works on bigger one
@@ActionBOX if u want to upgrade clamping unit in future try to use toggle clamping it will give more force
Everything is cool. The only thing I would change is injection port and pushing rods for the plastic product should be on same side. This would make sure all flows are inside the box and you can not see them
That was hard to do but I will try to make those improvements in the future. Thanks 😊
How easy is it to clean it for when you want to change plastic types?
Great question, it’s slightly wasteful as you need to run the new plastic continuously until the system cleans the old plastic. Takes around 9 minutes.
Holy shit, you guys are incredibly productive, skilled and industrious! Excellent explanations, too. True heroes, thanks for the videos.
No problem, and Thank You 😊. We appreciate it,
Dave
This channel is gonna blow. Vinh was here 1/10/22
Haha we hope so too! Please share our channel with others you think may be interested 😄 Glad you’re enjoying the content!
More than appreciation 👍👏
Thank you! Glad you enjoyed the video :)
This is... Impressive to say the least
Thank you I appreciate it 😊. any plans of building your own?
This is AWESOME!! Will it be open source? Any resources you are willing to share?
Yes, soon
What a great invention bro I love it from pakistan
Thanks! Really appreciate it 😄
Great build, just one question: is your machine so large because of the material volumes you are planning to work with?
It’s large to accommodate the very high stresses that are allied onto it.
Genius! Wow. Bravo!
Total cost? Anyway to go bigger cheaply?
Yes this can go bigger cheaply, but would then begin to require 3 phase power which most people don't have at home. If this is for a shop then its definitely possible.
Is that 2,2kw lichuan servo you are talking about?
Yes, that is correct
@@ActionBOX wow very impressive and costly also :D
Dude you deserve way more subs, huge love and regard from indonesia
Thanks I appreciate it 😊. Feel free to help me grow the channel, and share the video with friends who may be interested. Thanks Goblok,
Dave
Can you explain how you did the electrical. I'm an EE and would love to know how you figure out you needed 220V.
Did you film any of the design, fabrication, coding, or assembly phases? Would be a great series to watch if you did.
Ill make sure to add that in the future video. Cheers
What was the budget? Can't wait for the plans for all these machines.
Most of the money was spend on research and development. The machine itself can be made for several thousand dollars. I do not have the exact cost on hand, but when I build another one I will come back and let you all know. Thanks for all your support. Do me a favor and share the video if you liked it. Cheers, Dave 😃
this is fantastic! As an electronics guy with minimal mechanical knowledge, I'd *love* full design and partslist info if you ever decide to make it available... because I could really use a small injection molding machine like this. Anyway I've subscribed and belled you, and looking forward to watching all your stuff in the meantime.
Thats awesome! with enough interest I will definitely share the designs and make a more detailed video. Its just very time consuming so unless there is substantially more interest it is not worth my time. Feel free to help me out and share this in groups that may be interested 😃. Glad you enjoyed the video.
@@ActionBOX you're really good, I have no doubt you're going to get a lot bigger. But I'll do my bit to promote if it gets a design pack for building this project quicker. :-)
@@julianhigginson Thanks Julian, I appreciate that 😊.
I too would like more details on this machine, if making a video is not possible then perhaps some kind of write-up could be?
@@ActionBOX Nice!
Man those ball screws are MONSTERS :D BTW: should they sound like that? It's pretty crunchy.
i can already see the 10 million Sub special, you guys are insane!
😁, Thank You my friend !
This is amazing. I’d love to collab anytime you would. Certainly a type of machine I’d like to help contribute to bring to open source.
Keep up the great work. Subs will come in time.
I would love to collaborate. Let’s get in touch and discuss the details. Cheers.
@@ActionBOX great things are about to happen
@@maibster Thanks but he never responded 😔. hahaha
@@ActionBOX give it some time hes a busy guy^^ I believe
@@maibster Alright 😉
Nice work, looks like it can do serious work. Well done!
Thank You 😃
hi guys i am really impressed with this machine and would like to build one for my self would you consider
sharing the build plans for it
It's perfect project. I've been thinking about it for 2 years. I would appreciate if you share information where did you buy or maybe you mill the screw for injection. Basically I stuck on it.
Man, this is great. Do you have an estimate of the costs of the parts for this setup?
Instant sub.
Thank you very much! I will be posting a second video detailing all the specifications. In the meanwhile, feel free to help me out and share with one friend or group who would be interested 😃
Most likely a couple of grand.
I bought a nice electric log splitter with the intention of using that as a base for a injection mold machine. Had to sell it along with most of my stuff in order to move across the USA. I want to get stared and build it now but so many projects. Maybe in another yr or two.
The log splitter was 8 ton, or 16k lbs. I have studied DIY injection mold machines built by others for a long time and one thing is pretty constant, they do not have enough clamping pressure. I do like his machine but I would combine this with a simple hydraulic system for much more clamping pressure.
Might just buy an industrial model with 50 ton clamp system. Those are pretty cheap to buy but parts cost will kill you, specially the electronics. Mine will not be fully automated, I do no think I can come close to these guys skill on that level.
Hi, great project!!
How does the plastic stay in the injection chamber while it is being filled by the screw? Does it not come out of the injection chamber nozzle as the plunger retracts? Is there some kind of "closing valve" to prevent the plastic from flowing out the chamber while it is being filled?
Hi, Great question, there is a nozzle pressure valve, which is essentially a steel ball that is spring loaded. It only opens with sufficient pressure, such as that during injection. Otherwise, it seems against the steel body, so there is probably a theoretical leak, but it doe not affect function. Cheers
@@ActionBOX Thx, fantastic work.
Any way we can download the CAD files for your machinery? Or maybe, do you have some kind of pdf with more details.?
@@toshiba162 I hope to make them all available soon enough
@@ActionBOX Got it. One last thing, what are the clamping force and injection pressure in this system? Seems to me that industrial machines are always oversized in terms of clamping forces. The one you build probably doesnt exceed 5 tons right?
I'm here waiting for the follow up video or plans and BOM. Considering making this.
Hi Leon! Thanks for the comment. We have quite a few projects going on, so we’re planning on making a longer detailed video about the plastic injection machine in the near future. Meanwhile, stay tuned for some really cool upcoming machine videos! Cheers, Alan
Wow! Great job !
Thank you! Cheers!
Side question: how do you finish the leftover borders of the parts to get rid of the sharp edge from injection molding?
I’m not sure what you mean by leftover borders. Our parts come out as intended, with a break off tab that we cut off with cutters. Does that answer your question? Cheers
@@ActionBOX I mean that thin line some molded plastic parts come out with, any idea of how to buff those out without damaging the plastic?
nice work bro, this is sick. just one recommendation to put the hmi on the same side the operator stands on. Most places would consider reaching across the machine to operate it a safety hazard, haha.
Yeah, there is the actual engineering (which was hard enough) and then the human factor engineering which was too much for a single student to handle 😂. Great point though, and thanks for watching in detail.
Awesome biuld guys this is awesome. Do you guys have other parts in mind that you want injection molded?
Indeed we do. We have made some casings for projects here and there, and are super satisfied with the machine so far.
Could you try injecting shredded pla 3d print scraps? I think that would be far better option to recycling filament than trying to make new filament
Interesting thought, I’ll give it a try
@@ActionBOX Please do, I've not seen anyone try this yet. I've been pondering on getting a cheap diy injection molding kit for this purpose and to learn some CNC skills for making aluminium molds, but it would be great to see if it works first, or if there are some issues. Recycling PLA scraps with this would do great for local communities, and would be far easier to setup than consistent filament extruders.
I’m thinking I need to start with figuring out how to shred the pla scraps. Any thoughts?
@@ActionBOX for small scale and light weight pieces (e.g. skirts and support structures) I've used just a kitchen blender to get the pretty small. Looking at your workshop, I guess you could have the resources to get or build a "Precious Plastic Shredder" or something similar. Basically a scaled up version of a office document/paper shredder, with beefier metal teeth.
uffff amazing setup. Will you release the plans for build one ? Congrats !!
Yes I will be in the future. Glad you enjoyed the video, and don't forget to help me out in the meanwhile by sharing with at least one friend 😃. Cheers, Dave
@@ActionBOX I will for sure. I´m in a moment in my life that I simply urge to have a small injection machine. But that steppers are very expensive here, I have two nema 34 from a previous project, and will try to get 2 more. Also, I will redesign using leadscrews. I hope it works somehow.
@@carlosefreitas4040 Im sure it will. Good Luck
@@ActionBOX Would you mind to share what are the motors used in your project ? Thankyou :)
Such a great project. How did you machine the base plate?
I used my diy cnc machine. I’ll make a second video going into every detail in the future hopefully that will help. Cheers.
One best video n build great going
Glad you like it. Any plans of building your own?
I just found your channel. Instant subscribe from this tool and die maker! Keep up the great work!
Thank you, It is always nice to have a professional back up your hobbyist work. I hope you were able to enjoy the video despite your extensive experience 😃. Feel free to share with others who may be interested in this, it would help me out 😊.
Interesting build! I'm so glad that YT algorithm brought you guys up as the content is well worth watching for DIY and RnD public. Can't wait to watch the rest of your content as time permits.
Awesome, thank you! This means a lot to me. Please help me out and share the video with others who may be interested 😃
Amazing ... you're Paul Automatic talent ... Tell me it's going to be open source?
Or at least the programming ... ??
Thanks
Thank you my friend. Yes I hope to make this all available for free once I reach 1 million views. Hope you enjoyed the video and don’t forget to help me out by sharing my video with at least one friend. Cheers, Dave
This is awesome! I was looking into getting an injection mold machine for some products I do from laser-cut acrylic. Great job!
Cool. Co2 laser cutter? A new injection machine video is dropping in 36 hours so make sure to tune in 😊
Nice job. 👍
Thanks Collin! Glad you enjoyed watching 😃
How did you find the neccisary force to inject? I can find clamping tonnage requirements everywhere but nothing for injection.
That is a Injection molding machine on a budget if I have ever seen one. Good thing that you have stayed away from using hydraulics for anything. Makes it much more affordable and simple to produce.
Im really glad you recognize that 😂. Thank you for your support 😃
Are you guys going to do a detailed video on this mold press? I have a couple of ideas on things that I would love to mold.
We want to later this year. So yes. Cheers
Subbed! Very professional machines right here. Can't wait to see more detailed building procces videos... With this type of content and quality of machines an videos this chanel will grow up by itself. Keep it up mate!!
Thanks for the sub and the nice comment. I will be releasing more content soon.
epic build, gents!
Thank you. 🙏
What a great video - you guys have a very comprehensive skill set- Python, Arduino, Mach 3 as well as G code and no doubt more that I have not seen yet. Plus machining and design skills as well as a strong inventive flair as well as a healthy budget to buy parts !! Congratulations on an entertaining site ( yet more of the skillset- filming editing posting etc) wish you every success! Inspiring :)

Well you just earned a subscriber.
Thanks 😅
It's better to add fan above the mold clamp, to make the plastic cool faster so it will not deform when it being push to remove it from the mold
This is unbelievable! Thanks for sharing and keep it up.
Thank you! 😃 Feel free to share this video with anyone you think would be interested.
Wow it looks so polished and clean. How much did it cost approximately?
Thank you, I will post a followup video with all the details in the future as everyone is asking. Cheers.
