Hi, I’ve been thinking of buying a perforated flask vacuum casting
machine. I’ve vacuum cast with solid flask for many years. I’m
wondering if anyone here has gone from solid to preforated flask. I
often cast with only one item in a flask. Two and three items are
common as well. I cast mostly 14 and 18k gold, white and yellow.
acasionaly I cast 22 and 24k and sterling silver.
Is there an improvement in casting quality considering the small
batches I cast in?
