Making A Product From Scratch - Silicone Mold, CNC Machining & Resin Casting
Вставка
- Опубліковано 8 лют 2025
- Watch as I show the process of cnc machining the ‘master’, taking a silicone mold of the master, then resin casting into the mold to reproduce the part.
The part is a new DIY kit for mounting an air suspension controller into a vehicle interior. This kit is for the Accuair Elevel Plus controller.
Thanks for watching.
Curious why you didn't CNC machine the mold positives directly in the modeling board? It seems easier than maching the full item original and then building the mold enclosure by hand? It would also avoid issues with part flipping on the CNC, because you would machine the two halves of the mold next to each other.
Also, for us fellow resin casters, mentioning the chemicals you use would be greatly appreciated! I noticed a mold release agent, and I'm not sure what the black spray was.
Thanks for the fantastic content!
Thanks for watching and the comment! I’m assuming I’ve understood correctly, that you’re saying to machine both front and back positives from two separate model boards, then pour silicone over each to create both negative sides? If that’s the case, had originally thought to do it the way, although I did have my concerns/ reasons for not doing so. The concern was accuracy of the two silicone haves mating together, although I know we’re talking minor tolerances really, I wanted to avoid any flashing when casting the resin. There’s a 100% change of them perfectly mating together when the second pour of silicone is poured over the first set silicone half. I hope that made some sort of sense! This wasn’t the main reason, just something that crossed my mind and the following reasons eliminated the above as the way to go.
The main reasons I chose the way I did (which is the usual approach I take), is that I will always finish the part by hand, removing any machining marks. If I had machined the two halves from model board, all the text and details would have been positive, so properly finishing all of the surfaces without disturbing those details would have been tricky. The other reason was that I treated the machined part as essentially a prototype unless it was correct, then I’d treat it as a master and move forward with moulding it. I did 3D print various prototypes prior to machining, but having the physical master let me see and feel what the cast version would actually feel like. Hopefully that’s some insight to why I chose this method.
I will also primer and finish the part in Matt black paint, just so again I know what it will look like after casting. I also actually use the black paint to get a particular finish on the master and mist a few layers on, it’s not quite a wet coat, but also not just loose overspray that can be wiped off, kind of in the middle. This builds up a very very slight grain on the surface and gives it a nice uniform finish, which of course will be present on each of the cast parts.
Yes I should have listed the parts used. The release agent is brilliant, I use this while making the mould on the first side of the mould while pouring the second side of silicone as it lays on thin so won’t build and cause flashing issues while casting. Also it means I don’t have to brush anything on and accidentally disturb the master. I also use it while casting, again, it doesn’t leave a visible trace on the cast part (unless applied too heavily), so the parts surface finish remains as I intended it to look. It also keeps the mould ‘hydrated?’ and lets me get a fair few more parts cast before it’s burnt out compared to not using any. The spray for anyone reading or who missed it in the video is Mann Ease Release 200, and I believe it’s a Smooth-on product.
The resin I used in this video is called Xencast P2 polyurethane casting resin from a company called Easy Composites which I’ve added black pigment to. For this particular part it’s perfect, quick demould times and the strength properties are enough for this part, as it’s a kit that is meant to be cut down and fabricated into a vehicle interior trim. For my other products/ parts I’ll use the same resin, but add around 10% - 15% milled carbon fibre powder for better structural properties. The silicone is from a friends company called DWR plastics and I’ll be honest I cannot remember much regarding the details, as I’ve been having the same product from him for many years so I don’t even get bottles with labels anymore haha. If I find out I’ll be sure to update this comment. The model board was also from Easy Composites, the PU600 high density polyurethane model board.
I think that covers everything. Thanks for taking the time to write out your comment and thanks again for watching.

@@RTAFabrication Thank you so much for this detailed response - it is very valuable, there are so few resources for people trying to cast using polyurethane resins, especially with CNC mold machining. I'm mostly following the advice from the fantastic "Guerrilla guide to CNC and resin casting" by Michal Zalewski, but since he moved to the US, his advice on materials is mostly US-based and inapplicable in Europe.
Your explanation makes perfect sense. I am not making parts where surface finish is critical, so I never thought about hand-finishing the parts before molding.
That Xencast P2 is a fast-casting resin with a brutally short pot life! I'm even more impressed now. I'm looking at resins with a 15-30 minute work life.
Anyway, thanks for sharing all the information. I wish there was a forum specifically for people doing precision casting from CNCd molds using PU resins. The forums I've found so far were mostly about pouring epoxy on top of things (river tables, coasters, trays, ashtrays), which is entirely different.
I'll be waiting for your future videos :-)
The best silicon mold releasing agent I have found is good, old fashioned, pine sawdust. Rub it on real good and blow it off with your compressor. Much cheaper and very effective.
@@jrychter7 To add a recommendation, Robert Tolone is a mold maker with a lot of experience and with compact and informative videos, I always save that for a time when I can give it the attention it deserves. Also Rybonator makes dice making videos but some of his videos are really general required knowledge or research (he has one on the setup you need for resin casting and it's reasons) and a lot of the techniques he applies are useful for other applications of the craft, hope it helped someone!
@@jrychter7 There are quite a few vids on casting from 3d-printed molds you might find interesting, i don't remember seeing any that were PU resin specific, though i may have just missed that because it was the process i was interested in rather than the casting material.
You have captured many men's dream in a single video. Those who love crafts, those who want to create and build. The world would be so beautiful if every men could live like this, doing what they love, and share what they create.
Thank I appreciate that! I am very grateful that I’m able to make things and share the processes with people. Even more grateful people gather inspiration from it too. Very happy that I’m able to help people by sharing the work I do. Thank you for watching.
I feel you brother, life could be beautiful. We all do what we love, are nice to each other and love each other. It could be a paradise. But I don't believe it's possible.
Dude literally... My hobby is designing, manufacturing and basically everything in this video. The fact that you made this and made it in a way that was so easy to consume is just amazing. This is a masterpiece and I love it. Deserves literally 20 million views. This... UH... OMG. I literally am just amazed. This is awesome. The music was a PERFECT CHOICE!!! SO ELEGANT
Man, this guy is an artist. I never could've imagined someone can make someone fall in love with such a technical work!
This was absolutely beautiful. Watching this was like meditation.
I have been designing and making antennas for space and precision mechanical parts for 30 years and I was struck by your skill, patience, age. Truly Congratulations
Prob. the most beautifully made fabrication video I've seen, hope to see more in the future!
The beauty of doing things the accurate way, taking your time to create a master product is what I felt while watching. I have paused the video and stared at your work, once you completed it. I thought you would like to know some take the time to admire your perfection.
Watching the video it looks so simple...easy to ignore that there is a ton of design, engineering, time, investment and experience involved in the process. Well done mate, nice video, nice final product, nice music, great work! (almost 1 year after the video was posted)
Even though I have seen your videos 20-30 times now, every time I come across them, I just have to see them again. You are awesome...
I am totally impressed by a lot of things after watching this video. The skills (CNC, materials, etc), the craftsmanship, the camera work (angles) the editing (great music choice) and so on ... And I didn't even notice the connection to the automotive industry. Major props! 🙌
Man, this guy is an artist. I never could've imagined someone can make someone fall in love with such a technical work! God bless you brother!!
What a superb video! Loved the way you shot it, subject matter and manufacturing skills are superb. Well done that man!
Thanks for the feedback man! Glad you enjoyed it!
Working back from your latest I must say the decision to add a commentary to your videos was a good one. Always amazed by UA-camrs who manage to hit such high production values so early on 🙌
You make this look like a calming, relaxing experience. If I was to do something like this, the end result would turn out nice, but along the way, there'd be a bunch of screaming at inanimate objects because of my mistakes and a lot of swearing
This video (especially the intro with the machine running) along with the beautiful music is just absolutely peaceful and wonderful. Please do more like this. :)
Thanks!
Thanks for the super thanks! I appreciate the support! 👊🏻
Amazing work,the design philosophy you use on your builds and the production quality of your videos are at a very high level of execution. Im not even a car guy ....but I enjoy the fabrication aspects of your work! My basic fab work is in the region of Cosplay but your techniques transfer over just as well. If its not a secret, what material was that which was poured into the mould for the final black completed panel . Thanks again and keep up the inspiring workmanship! !
Thanks George! Haha I am very particular about pretty much everything 😂 I’m glad you enjoyed watching the video! Yeah I realised that most of the fabrication I do is inline with the cosplay/ prop making industry! The resin to make the final part is polyurethane, I’ll be honest I can’t remember the data sheet specs off the top of my head without looking though. I’ve added a pigment to it make it black too 👍🏻
It's a real fantastic, designing by drill pottering, then silicone molding then producing.
You proved you are a 3d printer, machine molding & producer of perfect product from scratch. You could brand your name on any copied products.
I design wood handy works for molding them then selling reisn products.
I am here even working since 1970 s was watching you as a student kid.
Thank you for making me trust human still can be better than machines. & machines are just a copy of a fantastic one mode of human art piece.
Enjoyed your video man, was just wondering what type or brand of silicon liquid that your using for the molds and also what type or brand of plastic your using to reproduce the parts?
I ran out of words, I kept watching the whole video without a moment of boredom.
It's so satisfying watching this video, I can't describe how I felt!
i don't usually comment on videos but I have got to say this is one of the best videos i have watched for cinematic style shots and good content. Can i ask what camera setup you are using? I am in the process of upgrading my filming equipment in the near future and the clarity of the dark areas on this without going grainy is incredible!
Thanks I appreciate that! My current setup is a Blackmagic Pocket Cinema Camera 6K (BMPCC6K) and I only used one lens for this video which was the Meike Full Frame 35mm Cine Prime. I also used a 1/4 strength Tiffen Black Pro Mist filter on the lens to take the digital edge off the image. The lights I used were the Aputure Amaran 200D and I used various modifiers throughout video on the light. I also used a few 2ft Godox tube lights as well. Thanks for watching!
The combination of the music, real sounds and the scenes were awesome
Amazing video! What type of CNC mill are you using?
Very interested in this too
The music the work and the simplicity makes you watch another video. I’m learning but I’m like watching a movie too because I’m enjoying all that I’m seeing. Thanks for the wonderful tutorial fabrication video.
All my life I have never seen anybody work to the standards I do! I am a perfectionist in my work and watching your attention to detail and pride in what you do I would genuinely like to hire you. Seriously it's nice to see a great quality product manufactured. Awesome video appreciate the thought to share and your high standards of both work and video editing👍👏👏👏👏SUBSCRIBED
Thanks Neil I appreciate the feedback and I’m glad you enjoyed watching! You’re not wrong there, I am a perfectionist and get obsessed easily to do things in a particular and meticulous way. I’m sure you can relate that there’s nothing better and more fulfilling than the process of working through a task and getting to that final result. Can I ask what type of work is it that you do? Thanks again for watching Neil and thanks for subscribing.
This might be the most esthetically pleasing video I’ve seen on UA-cam. Not only is the end-product beautiful (I don’t even know or care what it is), but the way it’s filmed is just amazing.
I could look at that CNC machine etch those fine details all day!
You’re a true artist!
Thank you Daniel! I really appreciate the feedback. I’m glad people are enjoying this video. I mentioned in another comment that when I’m doing this type of work, I find myself in a relaxed, focused state meticulously going through the process. I wanted to try to convey that same feeling into the video itself. It wasn’t the easiest task creating the part itself alongside actually filming, being mindful of composition and lighting for the video but the feedback has been great so it was definitely worth the effort.
I agree too, it doesn’t matter how many parts I machine, I always get transfixed on seeing the small details being machined. I’m the same with my 3D printers too, it takes some effort to pull myself away as I could watch both for hours haha.
Thanks again for watching!
@@RTAFabrication You’re very welcome man, am glad you saw my comment! Needless to say, subbed in hopes for more content like this!
(Oh, and the audio is just as nice as the visuals, love that you can still faintly hear the machinery do its magic underneath the soothing music)
@@crkvend Thanks for subscribing! This video in particular has suddenly had an influx of traffic with such positive feedback that it’s given me some motivation to start uploading more often.
Yes I was quite conscious of the levels when I edited this. It would have worked fine without any music to be honest, but I felt the soft music carried you through the video nicely, but you still feel connected to the visuals with the actual sounds from the environment.
Thanks again man, appreciate the feedback and you taking the time to watch it. More soon hopefully!
One of the most elegant videos I've seen on UA-cam! Brilliant! 🇬🇧
Thank you Jon, I appreciate that and thanks for watching!
¡Gracias!
Thank you Carlos! I appreciate the Super Thanks and for your support! Means a lot!
@@RTAFabrication I leave a comment, I hope can you reply ! 🙏
@@CarlosAvilesMartinez Is there a comment from you that I have missed? If there is I apologise. I have just tried looking but can’t find one. If you want to post it here in this thread I’d be more than happy to answer it for you 👍🏻
@@RTAFabrication Dont worry men, I read many aswers here and response my cuestions ! Thnks a lot ! 🙂
Absolutely blown away by the creativity and craftsmanship in this video! Can't wait to see more amazing content like this in the future! 👏👏
Whoa that was both facinating and soothing to watch!
Thanks! Glad you enjoyed it! 😄
Couple of things real fast.
You could replace the duct tape around the silicone +wood with clamps or a velcoro strap.
You could also replace those plastic disposable cups with silicone measuring cups that can be reused a thousand times for resin.
You have a beautiful process and it is a genuine pleasure to behold.
Oh man!! Everything else in my life hit pause for 13 mins while I watched this. So hypnotic!!
Haha, thanks for giving this your full attention! Glad you enjoyed it! 👊🏻
The views on this is underrated. Very beautiful but still convey a clear step by step method without even saying a word. Bravo.
Thanks for watching 🙂 Glad you enjoyed it!
I don't know what's more impressive. What you made or how clean your shop is.
not sure if I prefer the process and product or the actual cinematography, this is top quality. All of it.
Thanks Raphael! Glad you enjoyed the cinematography, as well the content itself! Thanks for watching 🙂
I'm not even really interested in resin casting but I watched this like it was an action movie. For something so "boring" you make it enjoyable to watch and attention grabbing. Aside from that the parts look beautiful, amazing work!
I insisted watching it all on normal speed even though im in a hurry just as a respect for your work... wish you more progress.
Thanks for watching! I appreciate you watching in normal speed and I’m glad you enjoyed it! Thanks for your kind words 👍🏻
That was engrossing! And love the meditative music!
Thanks! Glad you enjoyed watching!
well now, that was simply beautiful. i havent the foggiest idea what the final product was, but it looks spiffy and i want one.
Really nice part, very professional looking. Also, great music.
Bro !!!
🤯
Best most satisfying... non dialog... explaining video EVER !!!
I was looking for an idea how to build... cast or something... some screws mask rings for my speaker design.
Great video ! 👍
I'm so amazed right now. It's so relaxing and yet so pleasing to watch.
Thanks! I’m glad you enjoyed it 👍🏻
This was just beautiful, just amazing sitting here with my chin upon my hands and watching an artist. Thank You
Never thought of using hot glue for a temporary wood mold like that. Great video! And pretty music
Worth watching for the piano alone. Truly fantastic production, and a great manufacturing system.
Awesome creation with beautiful calming music. Amazing video you've produce. Greatly appreciated!!
I love your work and the way you film it ! Thank you very much. It's very inspiring!
Excellent work! I hope everyone understands how much work is actually involved to to get the product and this video done.
Kudos!
Watching this was like therapy.
Hi.
I saw lots of tricks at your video. You are very careful about the process that you did. The gloves, hairdryer, using lanset etc you are very good at your job. Completely amazing. Waiting for next video.
Thanks for watching! I do enjoy the process of making things, more than the final result most of the time. I find enjoyment in the meticulous steps you have to take and watching an idea come to life. Thanks again and I’ll have some more videos uploaded soon!
I learn from your works and you are simply great worker
Wonderful video
Congratulations to the person behind the camera too, who also has a real talent, in the cinematographic aspect of it
Thanks! I actually film and edit all of these videos myself, it’s a long process when doing the work as well but cinematography is also something I enjoy! Thanks for watching!
Wow. That made me remember my old CNC days. Nice work.
Thanks Marcelo! I’ve got such a love for CNC machining, what type of things were you machining in the past?
@@RTAFabrication First I ran sign parts when was an industrial design student, with big CNC to fit wood boards, then later on I did jewelry with a smaller 3 axis. Last was designing molds for plastic injecting shoe parts. That was 13-14 years ago. Now Iam an UX Designer, but eager to have a CNC and 3D printer at home just for fun.
Dude I have been researching ghost guns I new into 3d printing so I seen so much videos but this video was different. Around this time I fallen ill with the flew I enjoyed this calm video while in bed. This is soul. I will support this guy
Thanks for watching Hammond! I hope you’re feeling better and I’m glad you found some enjoyment in watching! Thanks for the support I do appreciate it man 👊🏻
I really love the details and the camera in this video. Great work and passion in make the mold and the video.
The attention to detail,
Is second to none!!
Beautiful 👏🏼
amen!
Thanks Paul! Glad you enjoyed it! 😃
One word, Wonderful ! Thanks for sharing this peacefull and productive production processes.
Thanks Arda! I’m glad you enjoyed watching it 😃
Know this: watching this video made me fell pure joy for as long as it lasted. Thank you for that….😊
Brilliant. Glad to have found this channel.
Thanks glad you enjoyed the video!
This vid has inspired me to take my hobbying around to the next level, actually pay a bit more attention to what I'm doing.
That’s great man! What kind of thing are you doing as a hobby? Similar sort of automotive fabrication? Thanks for watching 👊🏻
That was something else , beautifully produced and presented
the craftsmanship is on another level , really enjoyed it . keep it up !
Thanks Ahmed! I appreciate your comment and thank you for taking the time to watch!
That was relaxing AF. Brilliantly done
Thanks man, glad you enjoyed it!
outstanding accuracy. I've been mold making and casting for years but nothing on this level. NICE!!
Thanks Aaron I appreciate that! Thanks for taking the time to watch it too.
So enjoyable to watch someone expertly create, thx for the relaxing music too!
Thanks! Glad you enjoyed watching!
Hands down my favourite manufacturing process video. Felt like I was watching a scene from a Hollywood movie. 👍🤓
Thanks Joel! I’m glad you enjoyed it and thanks for watching! 😃
@@RTAFabrication I look forward to seeing more such videos Reece!
Great video, just love that there's no a single word.
wow!
I have no idea of what the product is but I really loved the video. Such a silent yet pleasant world!
Wow thank you for sharing. Very interesting. Well presented, nice sound track. Well done mate.
Most satisfying video I have seen this month. Perfect music!
Thanks for watching Steven! I'm glad you enjoyed it!
Hi, I have watched this video more than 10 times. I am so impressed by the quality you have achieved and your overall skill in that production.
Thank you Mike I appreciate that a lot!
Absolutely stunning video!
Mesmerizing video work,
stunning colour correction,
glorious choice in music,
terrific sound clips
and beautiful composision of everything together.
I am truly thankful to be able to watch this video, thank you very much!
god fucking damn dude,
the shot near the end, where you put the finished cast down on the table,
where everything is out of focus and then you put it down and its perfectly in focus gave me shivers down my spine.
i have never seen such a high quality video of a product then with yours.
Godspeed!
Thanks for the feedback on this and your kind words! I’m glad you enjoyed watching it and thanks for taking the time to write your comment. I’m working on some more videos at the minute in a similar style which I’ll hopefully have finished soon!
This is respect to talent needed to engage in the business of moulding, of which I have only begun after investing in a CNC, using Fusion 360 and now reaching Mould Tools. Thanks for sharing this very valuable video, I have given me more respect for the ART>
This was way more soothing than I expected lol
man I love your work and how precise and calm you work
Thanks Khemiri. I’m just completely obsessed with the process of making things and end up so focused meticulously doing each step. Thanks for the feedback and for watching!
I am halfway through the video but the video makes me so happy for some reason.
EDIT: I just finished the video and that is one of the best things I have ever seen. I was happy then, I am even happier now. Thoroughly enjoyed the video!
Thanks man 👊🏻 Really appreciate your feedback and I’m glad you found enjoyment in watching it 🙂
Man, I wish I could be as skillful someday. Very well done!
Nice job mate! I tend to throw thread along the seams that I glue for the mold frame, that way I've got an instant pull and break quick release of the corners. Great job!
Fascinating video, a lot of precision work for a great end result. With the well chosen background music found it to be a strangely relaxing watch!
Thank you Daryl, I appreciate the feedback! Yeah quite a lot of people have said similar things about it being relaxing which is nice to hear. I’m glad it’s been well received!
absolutely fantastic video. Could watch that a hundred times
Thanks for watching Lance! I’m glad you enjoyed it :)
I'M SO HAPPY TO SEE YOU BEING PRODUCTIVE. KEEP MAKING VIDEOS. 👍 LOVE & RESPECT FROM INDIA
Honestly, there are very few videos here on YT that I watch from beginning to end, but your video here is calm, interesting and at least meets what I needed.
Thanks for that and great work!
Thanks for taking the time to watch it through and for the feedback! I’m glad you enjoyed it :)
Just rewatching this, missing your awesome content
excellent craftmanship. great.
Just stumbled across the video. It was so surprisingly satisfying. Well done!
some of the comments about this video are bizarre and smack of "Green with envy" You have a true gift for production of products and you should exploit it at every opportunity. Having been an engineer for 40+ years I can honestly admire your ability in design, engineering and video presentation. keep doing what your are doing, you will gain a massive following.
Thanks for watching Chris. Yeah you’re right there’s been a handful of negative comments. I can only attribute those to being a projection of their own feelings towards themselves, so I never take it personally and genuinely wish them all the best. Thanks for your kind words, I appreciate everyone who’s taken the time to watch and leave a comment and I hope it’s been either entertaining and/ or informative for someone. Again, I appreciate the feedback and thanks again for watching!
sso beautifully and passionately done.
great vid man! I'm coming from the film industry and fell into the maker bubble with 3D printing a year ago. It hasn't left me since. seeing how you combine craftsmanship and a very slow but filmic video style is so refreshing in the yt space 🤙
still one of the most beautiful videos on UA-cam. I mean it
Thanks Daniel! Appreciate you coming back to watch. More soon hopefully 🤞🏻
Wow, it was a random video that i watched, and it was made perfectly!
Thanks Michael! I’m glad you found it and enjoyed watching it!
