I'm looking to make some vacuum casting parts for my project I got master parts. Could someone please guide me for following points (Pl. note I'm looking for advice not for quotation) :
Is it must to use vacuum casting machine to take the bubble out of silicon rubber mold? I'm seeking for any cheap alternative. I saw many hobby people using home made machines using small vacuum pump for this purpose and using microwave for curing the tool. Pl. share your experience or if any other possibilities.
Where can I buy raw material for silicon mold and different grades of PU materials to pour in the tool.
Any difference between RTV and Vacuum casting process ? Any web site dedicated for helping on these processes or book explaining these processes would be highly appreciated. Thanking you.
