Resin Casting Tutorial – How to Cast Resin

Things I cover: pressure casting resin using a pressure casting pot (pressure casting chamber) with Smooth On resin, pouring two part resin, cast resin mold, demolding, and mold release for resin. This is geared towards designer toys, but can be applied to anything like resin jewelry or resin crafts. This is part of a series where I go over the mold making and resin casting process.

Here are links to the tools and materials used in this video:

RESIN:

PRESSURE CASTING SET UP: Pressure pots are made for spray painting and have to be modified for this process. I have the 5 Gallon but also linked the 2.5 if you’re doing smaller work. I actually wish I had a larger unit:

RESPIRATOR: I use a North respirator with a gas and vapor cartridge. Make sure the mask fits your head size: Small/Med/Lrg.

The silicone I used for the mold is:

Thank you so much for tutorial. Also for the great tips for crafters that do not have all that fancy equipment and in any case don't need it for the scale that we do molds and casting, but really need to know the essential stuff to still mold and cast successfully! I'm greatful for people like you on YouTube!

[caletherault]

This is the chemistry I like. To the point and practical!

Amazing new series of tutorials. The explanations are very detailed. As someone who’s thinking about starting sculpting and casting I can’t thank you enough!

Great series of videos on casting and mold making - can’t wait for the fuller video on negative and positive pressure utilisation in molding and casting. Thanks a bunch

A different world to the world of resin casting that i worked in for 35 years. No use of the degas chamber, that was always my go to, the way i was taught. And such abundance of rubber and resin. Here in the uk it is very expensive, so we make the smallest molds possible, using the smallest amount of resin possible, no guesing in plastic beakers, all of our resins are weighed out gram for gram. I liked the elastic bands, that is the way i always held my molds together.

Yours are some of the absolute best tutorials on YouTube of any topic, Steve: concise, informative and very clear instructions 👍 (some folks ramble, mumble or a combo thereof ). You get right to the point! 🙏😊

I'm already scared.

This is an awesome video! Incredibly thorough explanation – thank you! I've saved it for future ref & will be back to watch again. Keep up the great work!

A good tip for getting rid of flashing in the mold after casting, I use masking tape to grab all the little bits of flashing. Works fast and grabs all the little bits that tend to stick because of static I just found your videos and I’m totally impressed with your skill and your ability to teach.

this is an extremely thorough tutorial, great video

Another fantastic video. I've found Steve's mould making and casting videos to be the best on YoutTube.

Regarding the depressurization, I use a yellow plastic coil hose (with quick connect) and set it up to degas out the window. It saves on hauling the pressure pot outside since my studio is far from any doors.

This video was more informative than the video Smooth On made for casting

[crystalbernard]

Very cool video. I love that the resin turns white, it looks so good. I think I just might try this.

Great video. I have to confess that this is the first time when, seeing one of these, I've realized that "pressure casting" actually means what it says. I always assumed that it was actually vacuum, which would (in my mind) motivate the air to work its way out. Thanks for making it obvious enough that even I realized what was being said.

This is the best tutorial I have seem about casting, and your way of explaining the process is also very relaxing and easy to digest. Thank you so much for such a hard work 😊

Toujours au top je vous suis depuis la france. C’est un vrai plaisir !! J’attends la prochaine video avec impatience.
