Very impressive: great video. Can i ask? would you say it would be possible to make a silicone mould of a bee honeycomb ? seeing it has hundreds of chambers, how would it be possible with the silicon rubber?
Why on earth are you pouring the silicone all over the master? That's a sure fire way to get bubbles in your mold. Pour into one corner away from the model and allow the silicone to find it's own level.
Thank you for the video. Your opening sequence is cool. BUT, when you get to the beginning of your project you are rolling through it at breakneck speed suitable for someone who has already been deep in the project: yet none of us has! To add to the speed issue, the constant pounding of what is supposed to pass for music makes you want it all to end! Your work is good. slow it down. Let concepts register in the viewer's mind and give the viewer time to store them visually before you move on to the next piece. The whole ABC thing landed on the screen in less than 5 seconds and was soon gone before those of us unfamiliar with this work could "get it". Nothing worse than watching a video or sitting in a class feeling like you are behind! Great approach to a technical problem! Just work a little more on taking us there with you! thank you again!
Hi again. I believe I've viewed this 100 times by now. My stumbling block is the inner core. Is this at all sculpted or just a piece to fit the inner core. If so how much room does one leave. And did you place keys on the inner core. Sorry this step has me perplexed and confused. Thanks and hope all is well. I enjoy your videos
For the inner core, it was a sculpted piece made from aluminum foil inside and then a shell of epoxy clay/magic sculpt. The keys follow up the core vertically in the form of channels on each face and fin-type structures on its sides. The core itself should have some taper to it for ease of removal. The wall thickness of the inner mold was around 3/8", in retrospect 5/16 - 9/32" spacing would have made it easier to demold without compromising its strength.
Your video really helped me out! Thank you so much ! I modify your method and am using it to make a wax model for a complicated ring design I came up with. Before I came across your video I had to hand form the ring which is time consuming so thank you once again ! You are great inspiration! I already made my first mold and am now working on my second 3 part mold.
Thank you for the kind words, I'm glad you took the ideas and ran with them. Would love to see what you came up with! Feel free to hmu on my Instagram @jasonpond.artist and send pics if you don't mind. Be well.
@@jasonpond.artist7833 thanks for the reply ! I’ll share some photos of the results I have made with the first mold. I’m on my second mold and warming up the wax pot to see how it molds. I’ll contact you on Instagram and send pictures there.
I made it using aluminum foil to rough out the shape and magic sculpt (epoxy clay) over the foil. Be aware that for a core everything has to taper to some degree or you're going to have a mess of a time removing it.
ah I'm a bit confused. description says used mold star, but video says mold max. 2 very different products. I know you said mold max has a good library life, but what about mold star? how different are they really? (I've only used mold star. dont have the $$$$ for degassing) especially for this 3 part injection mold?
Seems really complicated to apply this but it's a very good technique. I want to cast something like a bottle where the hollow inner body is wider than the neck so I think an approach like this might be needed. P.S. I love the Freddie Mercury reference lol
If the wall of the piece/part your trying to make are relatively thin and there’s no detail on the inside of the part, if you haven’t already look into rotocasting. May end up being a easier solution.
As of right now I don’t, the pandemic has left me without the budget to do personal/private work. However I’m always up for giving advice and or strategies for approaching a mold for a part.
9jan2021 at covid pandemic... i see this video and i subscribe.... great video great tutorial no talk to much 👍 music ?? eee.... i dont like it btw.... THANKS !!!
Thank you, it’s funny when you look at all the things that are produced on a daily basis that have wild complexity and try to reverse engineer it. Obviously this process isn’t flawless but it gets the job done.
Sadly no, it would set that mold on fire on contact. However you could do a wax casting and use that to do a lost wax casting. Hopefully I will get to do some aluminum/bronze castings in the future.
Thanks Jason, really appreciate you sharing this. I want to make a hollow mold for like a cap of my head- how would you recommend i go about that? would it be the same as the three part silicon mold as shown here?
Wow, this is amazing! Loved that you went into detail on how to do everything. The rib cage reminds me of a part I'm trying to figure out how to mold as it would be a 3 part mold I'm guessing but not sure. Any chance I can email you to show you?
Sure, it may take some time to get back at you as we are all juggling many a thing right now. With that said, I’m always up for sharing my insight on how to approach a project.
No idea if you've considered this already, but the best approach in pouring the silicone should be adding it only in one place, and maybe tilting the box to have it slide over the rest of the surface, as the more places you have silicone coming from, the easier it is for air bubbles to get trapped in the material.
I'm not sure this qualifies as "injection molding"... seems like regular resin casting to me. Also, the pressure chamber clearly says "max 50 psi", so pushing it to 60 is a bit too much. 😂 Anyway, cool project.
Hi. I have a question. After removing the clay with mineral spirits, is there any need for further action? I hear that the ingredients of mineral spirits affect silicone. Is it okay to pour silicone while mineral spirits remain?
vurtne that is great question. So it really depends on the product you’re working with. As a general rule of thumb most tin cure silicones are resistant to the typical chemicals that are often used in mold making/casting applications. However platinum cure silicone is very sensitive to chemicals during and after the mold process. However platinum silicone has a better print/register and a longer library life. It’s a give and take with those two primary products depending on the needs of the part and it’s application. In context to tin cure (which this mold is made of) mold making any residual chemicals such as mineral spirts, alcohols etc. should be pulled from the first few casting and you’re left with the typical library life that comes with tin cure products. I hope this helps. Be well stay safe.
@@jasonpond.artist7833 Does it mean that it is better to use a silicone that requires a little hardening agent rather than A: B = 50:50 type silicone?(Generally)
vurtne honesty that is a little past my expertise. I would refer to each individual products specifications and try to abide within what they are capable of. I like the 10/1 for no greater reason than I’ve had great/consistent results. In the future I look forward to exploring different products at different price points for the channel.
@@jasonpond.artist7833 Okay. I'm studying silicone mold casting and I've seen a lot of videos on RU-vid, but I got the most hints from your video. I'll keep watching.
kfame227 thank you I look forward to exploring different techniques and making new videos ASAP. Sadly in lieu of our shared situation it will be some time. Be well stay safe.
Great video and what an interesting project. For a mould that size I would have made a brush on silicon mould with a outer support shell. This would have saved you 50-75% of silicone with out compromising the casting result. Sorry Smooth-On, this will not help your sales.... ;-) And looking at the closeup shots I noticed the number of bobbles in your silicone is insane. So either degas the silicone before pouring (you can use your preasure tank for this), or brush on the silicone in a thin layer first and then pour in the rest. And when doing the casting under preasure will drive the resin into the small airholes. But boy what a great project. It is a sham, that I cant click the "like" multiple times here..... cheers.
Yeh I agree, I think it deserves extra praise 😊,I just had a little trouble with the text boxes but I’m gonna back you up and share this video with my other device (with a different account) so I can boost the amount of love given for a such a great demo 💓 ;xD
