Hello.
I'm a relative novice at casting resin parts (from silicone molds), however I'll be needing produce quite a few parts soon, so I was thinking of purchasing a degassing chamber and vacuum pump.
But I have a few questions involved in this:
1. I know about degassing silicone, but is it ok to de-gas resin that's already been poured into a mold? (to avoid bubbles in an intricate mold)
2. If question 1 is fine, would it be ok to use Easy Composites' 26L Degassing Chamber for a small piece as well? (say around the size of a golf ball)
3. Generally speaking, what is the minimum wall thickness I can produce with EC's Fast Cast Polyurethane

Many thanks to anyone who can help with any of the questions.

Hello

Do what Matt says and I will add one more thing.

If you have a paint pressure pot put the whole thing in before it cures and use a pressure of about 30 psi ( experiment maybe 15 psi will work I have gone to 50 psi). This will reduce the size of remaining air bubbles to the point of being invisible.
