I've built them extruder heads before for Ford interior door trim panels. I also built the heat staker assembly unit that assembled the components together. I'm a 31 year machine builder, tradesmen and now tooler. I love my trade!!!
Nice work
Sir, would you like be our agent in your country? we would pay you a lot.
Thank you! I am interviewing for a machine operator position in a factory making similar product and I am prepping hard. You broke it down perfectly.
Awesome, good luck!!
@@dansproshop I got the job, blow mold operator. Your info prepped me well for the interview! The plant manager was impressed. Thanks Again!
@@georgenemeth4837that’s awesome. Best of luck!!
Rare to find videos like this that aren't just advertising a machine!
Well described process. I am a retired lead plant engineer for a blowmolding company. We ran Uniloy 4-up machines.
Thanks! I’m very well acquainted with Uniloys!
Great video, and I love your enthusiasm! Thanks for teaching me about blow molding!
My pleasure! Thank you!!
What’s the split line like? can it be controlled to be almost invisible?
@@jbenham91 the parting line is determined by the mold. It’s almost impossible to make it “invisible “ but the better the mold, the better your finished product
I worked in a milk plant in Huntsville Alabama from '99 to '02 and we made our own jugs. I was fascinated the first time I saw it. I was there one day when routine maintenance had to be done on the machine. They were in the process of purging so we took some of that and made a baseball bat (extremely crude) and a few balls. You don't want to get hit by that stuff. It's extremely hard and dense. I got some the next time and made a hammer. I had to put it through quite a few heat cycles to get it how I wanted it but I was able to drive 16p nails into pine studs with it. It was unstoppable!
right, this is how baseball produced on our machine:

and this is how to produce baseball bat on our machine

pretty fascinating. Ever since I was a kid I'd look at a milk jug or a toy and wonder how they molded it.
I just got to say thank you for the video. I have worked at a that dealt with the little pellets for plastic molding. I have always wondered how they turned that pellet of plastic into stuff. I had a idea but wasn't sure exactly. I would mind even more videos about them it's a really neat process. Thank you for bringing us along.
Very detailed *how it's made* video I'd like to see more 😀
Cool! Thanks for the lesson as always.
Glad you liked it!
A long time ago I worked for a plastics company in Reno, NV. as a machine operator. I had to walk through the blow molding department to get to the department I worked in. I typically ran a couple of thermoforming machines (hot sheet of plastic lowered onto a mold then vacuumed into shape). But occasionally I would run a CNC 5 axis router. Most of the parts that I made were the plastic pieces that go inside of slot machines (like coin hoppers), or car parts. The company had several other departments: acrylics, press molding, injection molding, we even had our own recycling (chipper) machines.
Good job, can you be our agent in your place? we are professional manufacturer for this blow molding machine in China.
@jinjun-blowmoldingmachiner1835
that was a long time ago, around 2005.
I operate very different machinery now. I'm a semi-truck driver.
Thank you. Cool stuff. Work safe.
Thanks, you too!
I like the "no touchy" tape over that top button on the control panel. Lol
I work for the Jones Plastics. We do injection molding, crazy to me how similar yet different all of this is.
Fascinating
Nice work!
You should have auto deflashing built-in to the machine.
Minimize the work-load on the packer.
Nice jugs!
But seriously, do all of the jugs get tested, like with a pressure test? I work in quality at an automotive plant and an Off-road vehicle plant before that, and I'm curious about how inspection and testing goes into products.
Every single bottle goes through a pressure test before leaving the plant. A testing machine pressurizes each bottle to a specific psi of air and will detect any leakage of pressure over a given amount of time. This ensures that the bottle will not leak when filled with a liquid. Thanks for the comment!!
I work in a company where we have auto deflashing, so the next thing is the jug gets on the convoyer and goes automatically to the leak tester, where it gets pressurized and checked for leakage, after that it goes to the table packing, and then it gets tested visually by the packer.
Fun to see.
I made twine for close to 20 yrs. Very similar on the extruder. We made ours into a sheet than the went through an oven st stretched it into tape. The twisted into spools of twine.
Excellent example
Thank you!
Luvn the info❤
Thanks!
As a retired Master Tool & Die Maker your video answered my curiosity about this process. I've worked on a few injection molds over the years, but my last 30 years were in a gas turbine manufacturing Tool Shop. We built, maintained and repaired all the production tools required to produce our engines. I do have one question though. How does the bottom of the jug get sealed if the plastic piece going into the mold is open on the bottom? Thanks. 👍 ✌
It gets pinched together in the mold and while it’s being cooled. The two sides become one. Hope this helps!
Awesome video... it's always nice to see when people do what they post. What I mean is.. you and your attention to detail. Well maintained machine there, she shows some aging but still runs smoothly.
Thanks, for sharing your playground my friend.
I appreciate that!
This is the wheel machine works "

I’m interested in knowing more about blow molding
Great video, very informative! Older BM machines require manual deflashing, unlike many modern machines that integrate various automations such as leak testers, automatic deflating or post-cooling stations for large jerrycans. What are your thoughts on the All-Electric technology?
Electric is the way of the future with machine. Servo motors are fast and quiet. Longer life span. All in all. I like them
Great video.
We make bottles in our plant and fill with carbonated products too.
Our 20oz line has two blowmolder one can run 20,000 bottles an hour the other one runs 16,000 bottles per hour. Our filler runs product into bottle 800-900 per minute. Our 2 labelers run 500 BPM each.
Packer does 40 cpm.
Palletizer does about 1 pallet 3-5 minutes 49 cases per pallet. Our full pallet conveyor hold about 10 full pallets. The warehouse forklifts on a good day can't keep up with the line. We can run over 30,000 cases of 20oz in 24 hrs
What kind of machine?
10 cavity rotary?
What kind of machine is it ? You must be talking about PET blow moulding right ? Our Sipas can run like 5000 an hour. Maybe more but then everything else cannot keep up. I hears of a beast at the annual plastic show that can pump out something like that but that's a monster.
so, it is PET blow molding machine?
Wow it’s so old that machinery, did you use deflashing?
lol yeah she’s old but still runs great. And yea all the parts get deflashed in trim nests before leak leak testing
A couple questions:
1. Is the whole screw apparatus heated to keep the plastic molten?
2. Is there any risk in the plastic burning if it's kept at a molten temperature for too long?
3. Is the mold itself also heated?
Thanks for making the video!! I appreciate you doing it.
Great questions! Yes, the barrel and screw are heated. YES, you can burn the material in the barrel if it sits too long or if temps are too high. This is also called “soak time”. The molds are cooled with circulated chilled water. This helps to solidify the molten plastic and harden into its final shape.
here's my answer for your questions
1, a set of heater rings are placed on the barrel, to heat the plastic molten.
2, no risk, just same as injetion molding.
3, for blow molding, heating on the mold is no needed.
Good video. I worked in plastics for years. Nice to see that machine. Do you have stretch blow molders and or sheet extrusion machines ?
We have a couple extruders
So like some manufacturers do does the flash go back to the beginning of the line and get reground up to be sent through again?
Absolutely!!
Can you create and design some other types of plastic bottle and this machine makes it or is it just this one standard bottle?
The bottle is determined by the mold. The machine will make anything and everything. As long as the mold fits in the clamp. The machine can make it!
Very interesting... and I'm full of questions. Is blow molding the only process you have at that plant? Can the dies be switched out to make different shapes / sizes of bottles? Do you also make lids for the bottles at your plant? Are the lids also HDPE?
@@halcyonoutlander2105 Haha, that was quite the barrage of questions...
Any information on adjustments on the blow press bar?
Excellent content. Are the caps next? Do you make those as well?
We just acquired a blow molding machine but it's producing more scape than the real containers. The blow molding pin is damaging the container necks
Blow molding is a real art. Having a good blow pin, shear ring, and neck blocks means absolutely everything. Best of luck to you!!
Hi Bro, Our blow molding machine will not damage the container necks.Do you want to try?
this can be adjust by the machine supplier, next time, you choose the right supplier with good quality machine.
I’m interested
What are the tests that the product should pass by the quality team? Please can you do a video about that?
Have you ever made holiday decorations, like Santa's, snowmen, or jack-o-lanterns?
Can I make a blow mold plastic slide like a step 2 slide?
That’s how they are made
Sir what mold temperature of pp blowing and pet blowing? Same @ plastic injection?
Very different from injection molding. Totally different process
@@dansproshop as I said what temperature?
Hey Dan, I noticed when you were showing the control/operation screen, I noticed an American flag and a Chinese flag. Was this machine made as a joint venture between both countries?
Yes. It’s made in China. That button changes languages
Please how do set the carve line in blow machine my carve line is not showing
do you ever try to produce 5 gallon by PP instead of PC or PET?
Poly pro is a strange material. I haven’t had much experience injection it. I know it is widely used for blow molding, but I don’t see why you couldn’t.
Pretty cool, but was hoping for a wheel machine... those shuttle types put me to sleep!! Good video though.

This is wheel machine as you want.
How long did it take you to get good with that machine? Im looking for a new job and i hate HR saying you dont know anything when even someone in the field for 5 years will have to learn the ins and out of a unique machine
I would say it toke me at least two years to really know everything in and out of this machine. The machine itself is hard enough to learn, but then you need to know all about processing the product. There is a lot involved in blow molding that people don't understand. It really is an art.
Im used to seeing trim tooling and punch cylinders. That sucks you have to hand trim them!
Timers are the Honeywell timers?
All the timing is integral of the PLC
@@dansproshop When I had 4 timers they was big bulky , 4x4 you set the arrow to the minutes or seconds . Im sure they come out with a small timer the size of a pancake compositor by now
i want to buy a blow molding machine. Is it available for sale?
Hi Bro, Have you bought the blow molding machine ?
Should that door be opened with the machine on?
Is that the normal operating speed? It seems pretty slow
This is just for setup
What brand of machine is that
Akei
@@dansproshop cool I have hesta and sinco for blow molding and arburg for injection at my place
Our latest supplier can't get the threads right, so after they are filled the caper can't put them on properly, gets very messy very quickly.
I have a video if anyone is interested.
Trader horn? I'm not sure if that was a joke but to the best of my knowledge trader Horn went out of business
Sadly, that’s true. That’s why I did it. To pay respects to the best darn hardware store there ever was
@@dansproshoptruth is I miss them too.
He to change blowing pin down
But onc stetson not active
Why only running one side ? Would you be interested in working for a Succesfull growing blow molding company ? I can help you.
