I have been making a lot of molds out of QC-7 aluminum and have been very happy with the outcome. Up till now I have gotten away with the ejector pin holes as vents but now I need to vent a cavity to help it fill. The parts are run in ABS and I dont want a flash point. Just wondering how deep i can go till it will flash. My shutoffs are around .0005 to .00075 and they have never flashed. Plus I'm doing all this on manual machines Thanks :wave:
