Product Introduction
The Juyi Vacuum Investment Powder Mixer is a specialized machine for preparing high-quality investment molds in the lost-wax casting process. Designed for jewelry manufacturing and precision casting industries, it combines vacuum technology with efficient mechanical mixing to ensure uniform, bubble-free, and high-density investment slurry, resulting in exceptional casting quality.

Working Principle
1. Vacuum Mixing – The mixing chamber is sealed and air is extracted to create a vacuum environment, removing trapped air from the investment slurry to prevent bubble formation.
2. Simultaneous De-Aeration & Mixing – While under vacuum, the machine thoroughly blends gypsum powder with water, ensuring even particle distribution and consistent viscosity.
3. Precision Control – Integrated control systems allow users to set mixing time and vacuum duration, guaranteeing stable and repeatable results for every batch.

Key Advantages
• Bubble-Free Molds – Eliminates air pockets for smoother surfaces and sharper casting details.
• Increased Mold Strength – Produces denser molds with less cracking during burnout.
• Time-Saving Operation – Combines mixing and vacuuming in one step, improving production efficiency.
• Consistent Quality – Ensures repeatable slurry quality for reliable casting results.
• Durable & Easy to Maintain – Built with robust components for long service life and minimal maintenance.
