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.

Thanks Matt.

one extra remark, If you have a 2-part mould you'll have to watch out while degassing, Like Matt said your resin will expand while degassing, that may cause your mould to dislocate or pull out some resin so your part wont be filled with enough resin anymore.
