Kaya Cast Chamber Vacuum Invest & Cast Machine

Arbe’s tabletop Kaya Cast is a professional, easy-to-use, and highly reliable vacuum invest & cast machine. It supports both perforated and solid flasks: invest under the bell jar (left) and vacuum cast either inside the chamber with perforated flasks or on top with solid flasks. A single control handle directs vacuum to either side.

Flask Compatibility & Workflow

Key Features

What’s Included

Why Vacuum Assist Matters

• Investing under vacuum helps reduce bubbles/pinholes in investment.
• Chamber casting with perforated flasks pulls metal into detail from the sides and bottom, aiding difficult fills.
• Top casting with solid flasks remains a proven, versatile workflow when perforated flasks aren’t required.

Best Practices

• Keep pump oil at proper level and change per usage schedule.
• Inspect and keep gaskets clean for reliable seals.
• Do not exceed 5″ Ø × 7″ H when chamber-casting perforated flasks.
• Select the correct side (invest vs cast) with the control handle before applying vacuum.
