Adaptor Plates for Vacuum Casting

These aluminum adapter plates are designed to work with standard vacuum casting machine chambers, including the Arbe Kaya Cast, the Grobet Procraft, and similar vacuum casting machines. You can also use these plates with silicone gaskets to build your own vacuum casting metal chamber capable of accommodating 3–3/8" and 4" diameter casting flasks.

Each plate measures 7–1/2" in diameter with a 5–1/2" diameter lip. The solid-wall plate (121.801) features a 5/8" center hole for casting on top of the chamber. The two cutout plates (121.802 and 121.803) are sized to accept standard 3–3/8" or 4" diameter perforated flasks, allowing the perforated flask to sit down inside the vacuum chamber. Use with heat-resistant silicone gaskets to seal the chamber while under vacuum.
