Whether you're casting with resin or mold-making with silicone, you've probably been given the advice to use a pressure pot or a vacuum chamber.
This video explains a general overview of how pressure pots and vacuum chambers work, when to use a pressure pot and best resin casting practices, and when to use a vacuum chamber and the best practices for degassing silicones.

Hint from Nick Zametti: use a plastic bag to line your pressure pot, or at least to wrap your mould, in case of leaks!

I've used them both for a few years, now. This was a great explanation. There's a new self-contained vacuum chamber spamming all of the resin channels, recently, telling people to use it for their resin. It's too small, and there's just not enough time to work with the resin. Don't fall for the perceived convenience.

Thank you brother. That really couldn't have been much better. Why can't everyone be so easy to understand? I often give tutorials on other subjects. I am the commissioner of a top 100 league in madden mobile, and it's imperative to keep it simple when teaching my guys how to play the game and organize their teams. They don't all have the time or experience I have to figure it out, so I just teach them and tell them why we do things the way we do as I go. That part is so important, and you did that. The only thing that may make this any better would be to show more visuals such as examples of failures vs successful casts and pours. You had some visuals, and you were clear about the others. I think your target audience is following you very well though, and understand exactly what you are talking about. I think you knew that when making this video, so kudos. Have a good day.

Great video, thanks. I'm in the process of casting a part that has a closed mold, there's a small opening in which I end up putting a bolt, the part is casted on the bolt and that's that so there's little space for any air to move around. My question is, if the pressure pot compresses the air, does a closed mold collapse, reshape etc and will the air inside the closed mold shrink just the same? I'm about to pick up a pressure pot but thought I'd ask to see what your take is on this.

Good advice. One thing I've never seen is the use of a magnetic laboratory stirrer with a teflon coated magnet bar. One could add the resin in the mixing container, turn on the stirrer and then slowly add the hardener, being careful to avoid making bubbles. I imagine that it would be thoroughly mixed with few or no bubbles. Of course, when filling in around small objects such as wood blocks or pine cones, that air may become trapped under/around the objects, so a pressure pot may be till necessary.

I was very interested in your Pro Tip on pouring silicone into the bottom of your pressure pot. I hadn't thought about that and was recently watching another video where they recommended using an HDPE disc in the bottom. They linked to a relatively cheap one so I ordered one and, although I haven't used it yet, it should work fine. I am intrigued by the silicone though as I have another pot that I don't have a bottom for. Are there any downsides to pouring silicone in the bottom of the pot when my only use will ever be for casting? Thanks.

This was very clear, thank you! My biggest confusion is that the internet is super divided on whether "pressure-potting" the silicone before casting is appropriate, with advice ranging from "never pressure cure your silicon because the bubbles will spring back" to "it's perfectly fine, I do it all the time". I'm not going to lie, money is a huge issue to me, and I can't afford to buy both a pressure pot AND a vacuum chamber, with their associated pumps. If I need a vacuum chamber (and pump) to make the pressure pot work, then I best not invest in a pot right now. But... I really need to get these bubbles out of my casts. I may be SOL, but any thoughts you might have would be appreciated.
@AlumiliteCorporation
@AlumiliteCorporation 3 жыл бұрын
We totally understand! It's tough because every maker has a different method. If your castings have bubbles in the resin and that's what you're most concerned with, pressure pot all the way. It entirely depends on what you're making and what preventative steps you can take. For example, mixing slowly, pouring into one corner, etc. all helps bubbles in silicone molds release, so that when you cast with resin you'll have smooth castings.

I had a question regarding silicone molds. I recently used Thi-Vex to thicken silicone and spread it over a master to save cost, but found air bubbles trapped between the mold and master. I have a pressure pot, but was wondering if it would be effective in forcing those air bubbles out of the mold while it cures. The vacuum chamber seems to expand the silicone which I would not want since it would already be encasing the master.

What are your thoughts on casting in vacuum? As in pouring 3/4 of the way up the mold, putting it in the vacuum chamber, de-gassing it, then pouring the rest of the resin, then degassing that and letting it set in vacuum? Would that work? I'm asking because I have a vacuum pump and chamber, but if I can make it work with that, I prefer to not buy a compressor and pressure pot as well.

Hello! Could you please advice - no matter how hard we try, we still couldn't get bubblesfree cast. I suspect that plastic gets hard just too fast, after hardener is added it would take just 5-8 mins for it to get already hard and I just can't securely close chamber and add 4 bars of pressure in that time😅 Should we consider "longer living" plastics?

Hello, I discover your channel because I am interested to create my knife handles with wood and resin. I congratulate you for your videos and thank you already for your sharing. Also, I don't speak much English (I use an application for written English) and I would like to be sure of what I understood. the vacuum chamber allows all the air to be evacuated from an object such as wood. We dip it in resinel (which one?), colored or not, so that it fills all the free space. For the pressure pot, we can put the object in the prepared epoxy (mixture A and B, which one?), and this allows to trap the air in the object and to harden the epoxy around this object.no? so if I want to color heartwood, and marry it with resin, I first pass it in the vacuum, with a bath of colored resin, then in the pressure pot to make a handle with epoxy? thank you for your return, and your information on the products to use. good continuation Xavier

But I mostly use UV Resins NOT 2 Part Resins, (mainly because the cure time is so much faster and it's easier to keep things suspended in place in my resin) And I don't know how what you taught me in this video correlates to the use of UV resins...? Any and tips or tricks, for the use of UV resin in these two devices would be helpful.... And is there such a thing as a clear pressure pot? That might fix my issue because then I could UV light cure while my molds are in the pressure pot?

I’ve got a question, can you talk about open face degassing versus closed face (with ports) degassing of molds in a pressure pot. I recently was trying to degass Performance 80d with a 3D resin printed mold for my part I was going to cast, but it unfortunately foamed in the mold.

If you use a slow cure resin, would you still be able to use the vacuum tank instead of the pressure pot?

I’ve heard mixed opinions on a problem I run into. Of course I came to the channel that always gives the best description and process, so here I am. I use your Mold Maker (amazing btw) but when I cast in polyurethane I get ‘zits’ on the cast. Some have said cure the silicone at the same psi I use for casting the resin in. Assuming I do both in the pressure pot at the same psi (40) I’m wondering if this would fix the issue. I get the silicone will expand and the air bubbles will come back but if hammered with the same psi in the pressure pot when casting resin they should theoretically shrink back to the original cure. Very informative video as always and greatly appreciated!

Hey, where did you get the pressure relief valve for your pressure pot? Is it a 5/8”? I’m having trouble finding a chonker that big.

So the compressed air bubbles that get trapped in the resin remain pressurized after curing? So the resin object will be slightly pressurized after curing?

Hi guys! I want to start mold making, doni need a vacuum chamber? I have seen some people say that a pressure pot works fine, and others say that you need a vacuum chamber. I can't seem to find a definitive answer on the topic! Any advice?
