Casting resin with pressure pot!

casting resin with pressure pot

In today's post I'll talk a little bit about how I cast resin using a pressure pot.

The pressure pot I'm using is a 10 liter tank with internal Dimensions Height of 22cm and diameter of 26cm; it's got 60 Psi working pressure. Remember your pressure pot have to be specifically designed for resin casting!

How does pressure pot work?

Pressure pot compresses air bubbles to sizes so small that you will not be able to see them. That way you are able to achieve a fantastic high quality clear casting. I have pressured cast with silicone, plastic, pvc moulds and have not experienced any problems with those. Also it comes really handy when you're casting with difficult recesses and complex moulds.

So, let's get some casting done!

In my video I'm using two part resin from Resin Pro. I highly recommend their products - I've used them for quite a while now and their resin is really good quality and price is competitive, which is always a bonus.

The mould I'm using in this casting I've made myself from the pvc sheet and secured with sellotape and hot glue to prevent any spilage. For more information on DIY moulds, please check the video on moulds for resin casting and another one on how I'm making HDPE moulds!

Once the resin is mixed and poured into your mould, insert your mould into the pressure pot. Apply positive air pressure from any regulated compressor and leave to cure under pressure. Yes, when pressure casting you're going to need a compressor. If you have a good seal on your pot, the compressor will only be running at the beginning and then the pot will keep the resin under pressure the entire time while curing.

To see how my casting came out, please check out the video below! If you have any questions, please drop me a line below and will answer asap.
