Vacuum Investment Mixer

The Secret to Silky Smooth Castings The Imtex Vacuum Investment Mixer is designed to eliminate the most common cause of rough castings: air bubbles in the investment slurry. This integrated workstation allows you to mix the powder and water and pour it into the flasks under a powerful vacuum.

By removing air before and during the pouring process, the Imtex Mixer ensures that the investment plaster hugs every curve of your wax model perfectly. The built-in vibration table settles the slurry instantly, resulting in a dense, rock-hard mold that captures even the finest microscopic details of your design.

Key Features

  • Vacuum Mixing & Pouring: The entire mixing and pouring operation happens inside a sealed vacuum chamber, guaranteeing that no air is trapped in the mixture.

  • High-Torque Planetary Mixing: The heavy-duty wiper blade rotates through the entire bowl volume, ensuring a lump-free, creamy consistency in minutes.

  • Integrated Vibration Table: A variable-speed vibration platform is built directly into the base, helping to de-gas the flasks and settle the investment tightly around the wax tree.

  • See-Through Chamber: The high-clarity acrylic or polycarbonate hood allows the operator to visually monitor the mixing consistency and pouring level.

  • Variable Capacity: Interchangeable mixing bowls allow you to mix small batches (for 1-2 flasks) or large batches (for mass production) without waste.

  • User-Friendly Controls: Features a digital timer for the mixing cycle and simple valves for vacuum release and pouring control.

Ideal Applications

  • Jewellery Casting: Essential for Gold, Silver, and Brass investment molds.

  • Dental Labs: Perfect for creating precise dental molds where accuracy is critical.

  • Precision Prototyping: Used for high-fidelity reproduction of 3D printed resin masters.
