same here!! since those old time videos!! i do it as a job because of this dude toooo!!! its amazing to see the evolution of all these! i wish we had easy composites in BRASIL!!!
SAME!!! been following since i was in college and couldnt afford anything. now i just started to create molds and was able to produce carbon fiber parts for my motorcycle. I owe it to this man and his company. greetings from Philippines.
Agreed with all the above, I wish we had Easy Composites in Australia. It's difficult to get all the right gear, dodgy tacky tape and peal ply, trying to make do with whatever you can find! The previous bloke with Mini bonnet absolutely blew my mind 10 years ago, this information is absolutely priceless!!
I am honestly more excited for new Easy Composites videos than Hollywood movies these days. Thanks for delivering outstanding content and making the world a smarter and more capable place.
If you are planning to use CNC machining to make the pattern, I don't see why you can't just machine the mold and skip the whole process of making the pattern. You will still need to do some hand working to remove the machining marks and prepare a suitably smooth mold surface. You may even want to apply a hard surface coat. I'm just saying I think that making a pattern is obsolete now that we can use CAD and CAM.
For very short production runs or proof of concept/prototyping, machining the mould from tooling board would be fine; however, for production runs and repeated heat cycling of the tools, you need much more durability than a machined model board tool could offer. You can also use the pattern to make a number of tools rather than machining multiple tools.
Been following since i was in college and couldnt afford anything. now i just started to create molds and was able to produce carbon fiber parts for my motorcycle. I owe it to this man and his company. greetings from Philippines. i guess learning CAD is our next goal haha
you guys are single handly describing every step of a very complex manufacturing technique in such a comprehensible and great way one video at the time. Without you guys, formula student teams around the world wouldn't be able to make the carbon fiber parts of their cars 🤣👏
Impressive the time that can be saved as well as the accuracy obtained but far too complicated for a 61-year-old man...😟 I note that manual work is still necessary and that robots are not yet doing everything, at least for now! 😊
Glad it timed in well for you, yeah the design doesn't quite stop at the component, we had a look around and realised that this was a subject that had not really been covered before.
You know, as a truck driver, that had nothing to do with anything you guys do, and consequently will never be a customer, I just want to thank you for the high quality videos you put out on the process. I'm obsessed with them. It's incredibly interesting how it all works, and I appreciate you guys being so thorough. I literally watch every video you guys come out with. The dude in the video is a great presenter. Just wanted to let you guys know that your video's reach even those who aren't potential customers, and provide a great deal of entertainment.
Impressive. I feel like you could probably teach entire courses for people/ companies who want to go into composites. A lot of the trial and error could be avoided by attending classes with hands on experience. A lot of insanely overpriced niche parts could get so much cheaper if more people had the skills to design and produce these parts. Especially if using fiberglass instead of carbon fiber, for example.
This is a super handy video! Nice work... however, I thought you might be interested in the content of this video, where Jake explains a bit about how to sketch splines and why to do it the way he shows. Jake worked on the Autodesk Shape Manager team in Cambridge for a number of years, so really knows his stuff. ruclips.net/video/bsXB-ZeM0ZI/видео.html
I've become a composites expert over the past decade thanks to your incredible video. Thanks for your passion and dedication to teaching. I haven't made a single part from composite, but I know I could thanks to you.
This was really good, im a journeyman tool and die maker with about 5 years of experience designing injection molds in solidworks. Fun watching those skills applied to carbon composites
Im a member of my university's baja sae team and I wish i had this video sooner. Making the molds has been a trial and error process for us and a lot of the tips in this video were things I found out after machining a ton of molds. Hopefully in the future our molds come out much better!
I have watched so many of your companies videos you guys made me choose motorsports over aeronautical for BEng, thankyou! Is it possible for you guys to make a video on design considerations on the final parts themselves? Like how to plan the structure for known loads and then testing with finite element analysis? I have looked around and there seems to be only a few solutions available (at huge cost lol) for composite FEA? Thanks!
Generally CAD tools with such features are only available on the higher end CAD packages or as paid add on features which makes availability not easy. You may be able to access through your uni engineering department such software.
Thanks so much for continually producing content like this. It's unimaginably informative and helpful. Now I just wish you guys had a US-based shipping hub available!
This is amazing!!!! I’m looking to 3D print molds, and this will be useful. Thank you for making these videos, the quality keeps getting better and better!!!!
Thanks for the comment, yeah you get what you pay for! I was surprised that Fusion didn't have the functionality for parting lines (that I could find) most packages do.
plug/mold is made from softer, brittle material that can be machined easily, if you damage it you need to re-cnc it and cnc stock material is quite expensive too. Much better to make a strong fiberglass mold from the soft plug which you can re-use many times without fear. Also easier to sand/finish a convex shape
Thanks for the question. While it is possible to do this for prototypes and one-offs the reason that you would make a mould from a pattern is that you want the mould to have the same CTE (thermal expansion) rate as the part you are making, so for these carbon fibre parts you want a carbon fibre mould. Another advantage it that you can quickly make more moulds from a pattern for volume production.
Incredible, man. I'm so glad y'alls business model allows and encourages free knowledge of how to use the product to it's fullest. These are invaluable videos. Thank you so much.
Superb detailed runthrough, always appreciate the effort you put into making these videos. The backcatalogue of knowledge is getting quite comprehensive.
Every single video you release is such a pleasure to watch. The work you all do is brilliant. Thank you for all the free advice and different guides and tutorials. I always leave your videos feeling inspired and with more knowledge and understanding than I arrived with. Awesome mate.
I'm mainly a 3d printing guy with no composite making experience nor appetite to do one. Making mold is so complicated I think I need a degree just to do it. But this video proves me wrong. Thank you for the free education
I used to build composite tail rotor blades for attack helicopters. This channel is always a joy to watch as the information and techniques are spot on!
The engine cover we will laminate in a future video, the component itself is something we’ve made for another RUclips channel (V8Creative). The fuselage will feature next in a video about the machining of the pattern and laminating the mould. No current plans on laminating the fuselage but you never know.
The fundamental value of knowledge you are teaching in these videos is incredible ! As a start-up maker I'm following closely. As payback, I'll be sourcing materials from you. Thanks and Regards !
Fantastic video! I would love for the next episode in this series for you to cover CAD Techniques for ply design/creation for complex parts. Thank you for all of the hard work and amazing knowledge!
Some CAD packages will have advanced composite tools within them, or available to buy, to help with some part of the design process. The same goes with FEA tools to help you analyse the design. Similar with ply template and cutting tools.
Could you guys do a video on how you went about designing the brake lever mold you used in your 3D printed mould video? I think that would pair greatly with that video!
Watch your video at the beginning of your channel years ago and just got back into carbon and wow same persone same amazing knowledge probs sir big giant props
Thanks for coming back to us after all this time. Yep as one of the founders/owners of the company Paul's been here from the very start. Although we like think we've improved the production quality of the videos a little since then, our dedicated studio has certainly helped.
Helllo ECL, really great video! I have a question, if I want the same dimensions between my orginal part on CAD and the final composite part, should I adjust the scale of the part when I create the mold? Thank you
In general no, as the pattern should be the same size as the CAD drawing, and the mould will be an exact negative of the same dimensions. For some very precise applications, scaling can be done to take into account machining tolerances, CTE during curing processes etc.
For the parts shown, we have not added dimensionally or scaled the part for machining purposes. The parts are not super critical dimensionally so no additional tolerance is needed for the CNC machining and finishing processes being used.
Loving your content 😍😍 I think after multiple tutorials, I found myself in this world😅 Just out of curiosity, can you make a suspension control arms using forged carbon? Would be it applicable on the normal car? And how would you need to reinforce it? Thank you😊🥰
It would entirely be down to specific design calculations. Its unlikely to be seen on any road cars as often cost dictates the retention of traditional steel pressed parts. It may theoretically be possible on some race parts.
Thanks for another perfectly well done video.. as someone working with CAD daily my brain hurt watching the flanges getting made.. with a direction of Z and am angle of 90° the flanges would be perfect and would turn around the whole part.. but apart from that, the video was good as always!
Thanks for your comment. In this case with this model and Fusion, we found this method worked best without causing any geometry issues or the tool failing to work correctly. Other models and other CAD packages may work in a more simple way.
I'm sorry if this is not the appropriate comment section for this question. But what are the chances that you will explore basalt fiber composites in a video or as a product? I find it really fascinating that, what's basicaly a spun natural rock can have almost as high of strength as carbon fiber, and I would love to see a deep dive from you guys into that topic.
It isn't out of the question that we'll do something in the future but currently it isn't a product we carry in our range so unlikely to be a topic covered in the very near future.
*Abstract* Composite mold design is a fundamental aspect of producing high-quality composite parts. This video outlines key design considerations within CAD environments for creating effective molds. It emphasizes the importance of features like trim allowance, flanges, parting lines, and strategic use of draft angles to ensure easy part release. Additionally, the integration of mold clamping elements for accurate alignment is discussed. The video covers both single-piece and multi-piece mold designs, with specific techniques for generating stock, creating mold cavities, and adding clamping features. While the provided instructions are tailored to Fusion 360, the underlying principles can be broadly applied to other engineering CAD software. Disclaimer: I used gemini ultra 1.0 (on 2024.02.24) to summarize the video transcript. This method may make mistakes in recognizing words
Its great to see the old video's and see how far he has come in 10+ years and what is now possible to what was possible over 10 years ago. I have spoken to this guy over messages a few times and he is always so helpful. Is there a way of doing any injection moulding with carbon fibre yet or are you just making parts on the computer for plugs?
Plastic injection moulding is not a composite process at this level yet. Resin infusion and resin transfer moulding processes do exist albeit they are slightly different in both the approach and technique. There are some overlap with some composite processes, eg infusion uses vacuum in a bag to draw resin into the mould. Forged carbon fibre is a compression moulding process between 2 tools. So there is some cross over in some areas albeit there is not injection moulding in the traditional plastics sense.
For low volume applications, prototyping etc, you certainly can use the EB700 Epoxy Tooling block as a mould. However, in general and for most uses, a proper composite mould, as shown, offers better durability and finish for the tooling.
Thank You so much for all of the information over the years. Is there any chance of a video for bladder molding into an aluminum split mold? I am on the hunt for bladder making materials at the moment. Thanks again!
Its something we might cover in a future video. The bladders are generally bespoke to each application with different people having different preferred materials and methods so it is hard to give an easy solution that works for all/most.
For very short production runs or proof of concept/prototyping, machining the mould from tooling board would be fine; however, for production runs and repeated heat cycling of the tools, you need much more durability than a machined model board tool could offer. You can also use the pattern to make a number of tools rather than machining multiple tools.
I might have missed the reason why one would choose to make a carbon fiber mould rather than a machined mould. That extra step looks unnecessary but I am sure there is a good reason for that. Any one can explain ?
Commonly it is for high temperature applications such as pre-preg. The thermal expansion of the mould is then almost identical to the expansion of the materials being used in it which can be advantageous in some situations. Machined moulds from tooling board generally have a limited lifespan and billet metal machined tools can be very expensive to produce both in material and machining costs.
i love that joystick thingy you have for moving in 3d, mind sharing what that is? been doing 3d work for years as a hobbyist and yet to see such a stand alone controller!
I was hoping to see what will be done to the backside of the engine cover. I'm trying to figure out a good way to add the parts that will be attatched to the top of the engine.
We aren't quite finished with the engine cover just yet so keep an eye out for the next installment. Generally speaking the mounting features can be one of the more complex challenges to overcome as the injection moulding process usually used for these components is allows for much more intricate geometry to be produced. Quite often it's a case of salvaging mounts off an original part and bonding them in place or fabricating a bracket in place of the original.
EU gostaria muito de aprender sobre isto, seria legal se o vídeo fosse em português, eu estou terminando a fabricação da minha Router CNC, e gosto muito de assunto de moldes
Ultimately it depends on a few factors, type of mould, use of mould and the size. They (and some other variables) can influence the design of the mould laminate you end up using.
Thanks for the feedback. Yes the features are pretty small so bridging wasn't really an issue due to the way it was lamainted. The laminating video will be ready soon so keep an eye out for that. It'll probably go live on the website first, so check back in the next week or so to see how we did it.
Спасибо. Интересное видео. Я делал прототип пятиметрового каяка в Solidworks, для изготовления формы и тоже был вариант сделать для каждой половины формы отдельный прототип или сделать модель лодки целиком и после снять с неё форму обычным способом. В итоге остановился на втором варианте, так как не был уверен, что получится сделать идеально совпадающие половины прототипов. Вернее одинаково подготовить фрезерованные половинки к снятию с них формы, ведь их поверхность нужно прежде зашпаклевать, покрасить и полировать. Вот так выглядел мой прототип перед снятием форм: ruclips.net/video/-6YI0N9QDsQ/видео.htmlsi=eHikgSHDfKySecpi
Hello. Are you planning to make a second part of this video? It would be great if you continued making the drone. Namely the wings and tail. Thanks for your work. I'm looking forward to the new videos, they're like a breath of fresh air in the world of composites.
There will be another video that features the UAV fuselage but that one will cover the machining of the pattern and the laminating of the mould sections. We do also plan to do something on wing construction so you might be in luck there!
I am confused. We use the actual finished cover and its dimentions to make the first mould. After we do the surface split, the top of the model becomes the top of the mould. and than when we make the part (use fibers), the top of mould becomes bottom/inside of the model. dont we loose the tickness and dimentions of the original part by doing all that?
The moulds are female compared to the male part. So the internal dimensions of the mould fit over the part model perfectly. When you lay up into the mould, the amount of material determines the part thickness. The external dimensions stay the same.
I love my luck and what the universe brings me. I have been trying to learn how to cut a body from a meshbody and I asked the 'experts' about it a few weeks ago, on numerous facebook groups. I was getting a lot of useless answers and my project got stalled because I had an uneven surface and I needed to use it as a tool to cut another body from. I have spend this last weekend also looking for the solution, without success (reading about b-rep and boolean stuff). So, out of boredom and frustration, I've decided to just watch some composite-related stuff and relax and vent my frustration. I thought I was going to lose consciousness when the video reached the 13th minute and I accidentally saw the solution to my 2-3-week search. THANK YOU!!!!!!!!!!!!!!!!!!!!!
Its our pleasure - we really get a kick out of making these videos and the help it can give so it is always great to hear they're working for people :)
Certainly not a stupid question! In some cases it is perfectly possible to machine the mould directly. For prepregs or resin systems needing a higher temperature cure, there are a few things to consider though. Tooling board materials only have a limited life and generally won't last as long as a composite tool. You can of course machine tools form aluminium etc but this is very costly. One other big factor is the thermal expansion of the materials. The most accurate moulding can be achieved by using the same materials in the mould that will be used in the parts. This way the CTE is aligned meaning any expansion/contraction of the part and mould happens simultaneously which therefore reduces warping and distortion and pre release of the part.
Question/suggestion: Pls show how you design the actual part figuring out the fiber layers, their shape, total thickness etc. Is there a feature in Fusion which can design a laminated object calculating for layers of thickness and their shape, split the shape into shapes that can be cut on a plane surface, create cutting stencils for the plies and so?
Some CAD packages will have advanced composite tools within them, or available to buy, to help with some part of the design process. The same goes with FEA tools to help you analyse the design. Similar with ply template and cutting tools.

Thanks for your comment. In this case with this model and Fusion, we found this method worked best without causing any geometry issues or the tool failing to work correctly. Other models and other CAD packages may work in a more simple way.
Like before even the video start 🙏✌️
what is the name of the CNC milling you used on this video ?
I'm sorry if this is not the appropriate comment section for this question.
But what are the chances that you will explore basalt fiber composites in a video or as a product?
I find it really fascinating that, what's basicaly a spun natural rock can have almost as high of strength as carbon fiber, and I would love to see a deep dive from you guys into that topic.
It isn't out of the question that we'll do something in the future but currently it isn't a product we carry in our range so unlikely to be a topic covered in the very near future.
*Abstract*
Composite mold design is a fundamental aspect of producing high-quality composite parts. This video outlines key design considerations within CAD environments for creating effective molds. It emphasizes the importance of features like trim allowance, flanges, parting lines, and strategic use of draft angles to ensure easy part release. Additionally, the integration of mold clamping elements for accurate alignment is discussed. The video covers both single-piece and multi-piece mold designs, with specific techniques for generating stock, creating mold cavities, and adding clamping features. While the provided instructions are tailored to Fusion 360, the underlying principles can be broadly applied to other engineering CAD software.

Merci pour les explications, super vidéo 😊
Merci d'avoir regardé!
Its great to see the old video's and see how far he has come in 10+ years and what is now possible to what was possible over 10 years ago. I have spoken to this guy over messages a few times and he is always so helpful. Is there a way of doing any injection moulding with carbon fibre yet or are you just making parts on the computer for plugs?
Plastic injection moulding is not a composite process at this level yet. Resin infusion and resin transfer moulding processes do exist albeit they are slightly different in both the approach and technique. There are some overlap with some composite processes, eg infusion uses vacuum in a bag to draw resin into the mould. Forged carbon fibre is a compression moulding process between 2 tools. So there is some cross over in some areas albeit there is not injection moulding in the traditional plastics sense.
Very interesting video, but why do you machine a master for the drone? can't you just machine the moulds directly?
For low volume applications, prototyping etc, you certainly can use the EB700 Epoxy Tooling block as a mould. However, in general and for most uses, a proper composite mould, as shown, offers better durability and finish for the tooling.
Amazing content, thank you!! if you have a branch in America I would only by from you guys
We can ship most of our products to the US with the major couriers.
Thank You so much for all of the information over the years. Is there any chance of a video for bladder molding into an aluminum split mold? I am on the hunt for bladder making materials at the moment. Thanks again!
Its something we might cover in a future video. The bladders are generally bespoke to each application with different people having different preferred materials and methods so it is hard to give an easy solution that works for all/most.
Great video! Why don’t you invert the cnc mold and use that as a final mold instead of making two? 😄 thanks for all the knowledge you shared 😄
For very short production runs or proof of concept/prototyping, machining the mould from tooling board would be fine; however, for production runs and repeated heat cycling of the tools, you need much more durability than a machined model board tool could offer. You can also use the pattern to make a number of tools rather than machining multiple tools.
@@easycompositestv Great response! Thank you 🙏🏻😄
I might have missed the reason why one would choose to make a carbon fiber mould rather than a machined mould. That extra step looks unnecessary but I am sure there is a good reason for that. Any one can explain ?
Commonly it is for high temperature applications such as pre-preg. The thermal expansion of the mould is then almost identical to the expansion of the materials being used in it which can be advantageous in some situations. Machined moulds from tooling board generally have a limited lifespan and billet metal machined tools can be very expensive to produce both in material and machining costs.
i love that joystick thingy you have for moving in 3d, mind sharing what that is? been doing 3d work for years as a hobbyist and yet to see such a stand alone controller!
It is known as a "Space mouse" and there are a few different models.
Spearfishing can ?????????
I was hoping to see what will be done to the backside of the engine cover. I'm trying to figure out a good way to add the parts that will be attatched to the top of the engine.
We aren't quite finished with the engine cover just yet so keep an eye out for the next installment. Generally speaking the mounting features can be one of the more complex challenges to overcome as the injection moulding process usually used for these components is allows for much more intricate geometry to be produced. Quite often it's a case of salvaging mounts off an original part and bonding them in place or fabricating a bracket in place of the original.
EU gostaria muito de aprender sobre isto, seria legal se o vídeo fosse em português, eu estou terminando a fabricação da minha Router CNC, e gosto muito de assunto de moldes
The closed caption option offers auto translation, although its ability to correctly translate complex engineering terms is limited.
Thanks for the great video!
She practical CAD technique on my mould design till I composite pattern
I was wondering, how do you consider the thikness of the matirial designing the mold?
Ultimately it depends on a few factors, type of mould, use of mould and the size. They (and some other variables) can influence the design of the mould laminate you end up using.
I think I love you
Thanks for the great videos.
Did you manage to avoid bridging on the locating features/Clamping bushes (35:00) without any radius?
Br
Thanks for the feedback. Yes the features are pretty small so bridging wasn't really an issue due to the way it was lamainted. The laminating video will be ready soon so keep an eye out for that. It'll probably go live on the website first, so check back in the next week or so to see how we did it.
@@easycompositestv Thank you for the quick reply.
I will look forward to the upcoming video.
Спасибо. Интересное видео. Я делал прототип пятиметрового каяка в Solidworks, для изготовления формы и тоже был вариант сделать для каждой половины формы отдельный прототип или сделать модель лодки целиком и после снять с неё форму обычным способом. В итоге остановился на втором варианте, так как не был уверен, что получится сделать идеально совпадающие половины прототипов. Вернее одинаково подготовить фрезерованные половинки к снятию с них формы, ведь их поверхность нужно прежде зашпаклевать, покрасить и полировать.
Вот так выглядел мой прототип перед снятием форм:

Hello. Are you planning to make a second part of this video? It would be great if you continued making the drone. Namely the wings and tail. Thanks for your work. I'm looking forward to the new videos, they're like a breath of fresh air in the world of composites.
There will be another video that features the UAV fuselage but that one will cover the machining of the pattern and the laminating of the mould sections. We do also plan to do something on wing construction so you might be in luck there!
It will be wonderful! I'm looking forward to it!))))@@easycompositestv
I am confused. We use the actual finished cover and its dimentions to make the first mould. After we do the surface split, the top of the model becomes the top of the mould. and than when we make the part (use fibers), the top of mould becomes bottom/inside of the model. dont we loose the tickness and dimentions of the original part by doing all that?
The moulds are female compared to the male part. So the internal dimensions of the mould fit over the part model perfectly. When you lay up into the mould, the amount of material determines the part thickness. The external dimensions stay the same.
@@easycompositestv Aaaaa. thanks for the answer. that makes more sence
Your flying wing likes like Skywalker X8 but smaller, also I found that the nose is a bit sharp than in original X8.
Yes it's very similar to the X8, about 20% smaller but being carbon the internal volume is larger. Thanks for watching!
I love my luck and what the universe brings me. I have been trying to learn how to cut a body from a meshbody and I asked the 'experts' about it a few weeks ago, on numerous facebook groups. I was getting a lot of useless answers and my project got stalled because I had an uneven surface and I needed to use it as a tool to cut another body from. I have spend this last weekend also looking for the solution, without success (reading about b-rep and boolean stuff). So, out of boredom and frustration, I've decided to just watch some composite-related stuff and relax and vent my frustration. I thought I was going to lose consciousness when the video reached the 13th minute and I accidentally saw the solution to my 2-3-week search. THANK YOU!!!!!!!!!!!!!!!!!!!!!
Its our pleasure - we really get a kick out of making these videos and the help it can give so it is always great to hear they're working for people :)
very cool!
Excited and expected video 🎉
Thanks for watching!
Maybe it’s a stupid question but why not machine the mold directly ? Why go through the pattern process ?
Certainly not a stupid question! In some cases it is perfectly possible to machine the mould directly. For prepregs or resin systems needing a higher temperature cure, there are a few things to consider though. Tooling board materials only have a limited life and generally won't last as long as a composite tool. You can of course machine tools form aluminium etc but this is very costly. One other big factor is the thermal expansion of the materials. The most accurate moulding can be achieved by using the same materials in the mould that will be used in the parts. This way the CTE is aligned meaning any expansion/contraction of the part and mould happens simultaneously which therefore reduces warping and distortion and pre release of the part.
@@easycompositestv That makes a lot of sense, thank you for answering !
Question/suggestion: Pls show how you design the actual part figuring out the fiber layers, their shape, total thickness etc.
Is there a feature in Fusion which can design a laminated object calculating for layers of thickness and their shape, split the shape into shapes that can be cut on a plane surface, create cutting stencils for the plies and so?
Some CAD packages will have advanced composite tools within them, or available to buy, to help with some part of the design process. The same goes with FEA tools to help you analyse the design. Similar with ply template and cutting tools.
cool to know, thanks!! @@easycompositestv
Could you please do a video about layup in such cavity moulds?
It is something we may cover in future videos.
