Arbe's tabletop Kaya Cast is a professional, easy-to-use, and highly reliable vacuum invest & cast machine designed for serious jewelers and metalsmiths. It supports both perforated and solid flasks: invest under the bell jar on the left side, then vacuum cast either inside the chamber with perforated flasks or on top of the chamber with solid flasks. A single control handle directs vacuum to either side, keeping the workflow intuitive and efficient. Powered by a German-made dual-stage vacuum pump and built in the USA, the Kaya Cast is engineered for consistent, reliable performance in a professional studio environment.
