The vacuum casting process draws vacuum on the mold before the air-free metered and mixed material is dispensed into the mold. The resin materials are vacuum degassed in the vacuum casting machine’s supply tanks. The air-free mixed material is dispensed into equally air-free, open or closed molds from the top or the bottom, while the mold is maintained under constant vacuum.
