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.

Perfect, thank you! I ordered a pressure pot a couple days ago. I was concerned about my choice but now I know I ordered the right tool.

Years ago I worked at a R&D company where we used vacuum chambers to remove air bubbles from small mixed batches, of long-cure-time epoxy before we applied it to our parts. So I always wondered why the guys working with resin mixed with wood for (lathe) turning always used pressure pots instead of vacuum chambers. NOW I KNOW! Thanks.

My roommate just gifted me a pressure pot as a late birthday gift. I didn't think it would be so easy to find such great info for it. Thank you so much!

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.

Thanks for that. I'm a wood turner. Most of the voids I fill are on curved and vertical surfaces. I use plastic hot glued to the wood to make a mold. If I seal the mold completely with no vent does the pressure pot still work

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.

THIS IS WHAT I NEED, BIG THANKS TO THIS CHANEL

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.

Thank you so much for the information.

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.

Great video, but I have been using Alumilite clear for 2 years and I vacuum de-gas the mixture before pouring it into the mold. Alumilite TDS recommends this. I use a 1-gallon pot, which degasses quickly. Usually under 1 min. I then have about 6 min to pour.

Hello there! first things first: GREAT VIDEO! it solved my doubts on the topic in a perfect way! thank you so much for it! then, I'm sorry to bother you, I would like to know one thing before buying a pressure pot: I cast reeeeeally small pieces for my miniatures (for example a head of a 28 mm miniature), so my moulds are often small (2 cm x 2 cm x 2 cm).. my question is: if I put them in the pressure pot, isn't there the possibility that the mould collapses for the pressure, and the result is a deformed piece? or the pressure is just enough to make the air come out without deforming the "walls" of my mould? thanks for your time, and again.. great video!

Hi there, great video! Do you think that is it possible to build a pressure form 8' long x 4' wide x 3" deep, put the wood and epoxy inside to build a river table ? Is it sounds crazy ?

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.

Couple of questions: I'm using a 24 hours epoxy for sealing burl woods, building a vacuum chamber for it now. Is it better to build the pressure chamber instead? Also, can it be made out of playwood (17mm thick) ?

Extremely useful info :)

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.

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.

Sweet right to the point, thanks brother

What if I put the final resin mold in a vacuum chamber and leave it until it hardened instead of vacuum first then put it in the mold, will it work? I just bought a vacuum chamber and I thought it's best for resin. So again if I mix my resin pour it in my mold then put the mold in the vacuum chamber suck the air out and leave it for few hours will it work? I'm using silicone mold and deep epoxy resin!

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?

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?

I'm casting really tiny parts(needles for instrument clusters) and due to the size I have found running air vents in my mold makes them unusable because they break by the time I can sand it and polish it back to smooth. One piece molds have the issue air being trapped in the small needle shaft, the pressure pot is able to overcome it for the small needles but the RPM and Speedometer needles that are longer the pressure pot can't overcome it. Is it practical in my use case to fill my silicone mold in the vaccum chamber and to run it in vaccum to force the trapped air out of the needle shaft in my mold so resin can fill that area before going to the pressure pot? I'm using alumilite amazing clear clast and my molds are platinum cure silicone

Okay this was helpful, so thank you! 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?

so a vacuum chamber should be fine then if you are using slow cure resins right? I have mainly been using art resins with a 24+ hour cure time so it seems like a vacuum pot should be fine to use on those and the silicone casts

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

Will a pressure pot help push the resin in the smaller gaps of a silicone mold?

which would you use for casting aluminum?

I use epoxy to cover tumblers that I have customized. What would you recommend for that? I assume the pressure pot but I need to be able to spread it on my tumbler before it sets up. Your thoughts?

@AlumiliteCorporation

3 жыл бұрын

Hi Diane! For tumblers, we actually wouldn't recommend either. Pressure and vacuum work great for castings, but coatings come out clear because they're thinner pours (so the air bubbles have just a quick trip to the surface!). Using a torch or heat gun after you've coated your tumbler will help pop any stubborn bubbles.

Quick question, can you use the pressure tank as a vacuum chamber? Since they are relatively small, their surface is also small. Remember pressure = force x area... the atm pressure on the walls might not be that hard and hence, you could do both pressure and vacuum with a single tank. Is it a bad idea?

Good information
