The St. Louis 82-6 Investment Mixing Machine automates mixing and pouring investment under a controlled vacuum environment to help reduce bubbles and casting defects. With throughput up to 18 flasks per hour, a two-speed mixer, and a built-in vibration table, it consolidates what are typically separate mixing, pouring, and vacuuming steps into one streamlined workflow.

Features

  • Vacuum mix & pour: Mix and pour investment under vacuum for consistent, low-porosity results — vacuum pump not included.
  • Two-speed mixing with timer: Set your cycle and let the machine handle agitation.
  • Enclosed mixing drum: Place flasks inside the chamber beneath the mixing blades.
  • Integrated vibration table: Vibrates flasks during pour to help release trapped air.
  • High throughput: Process up to 18 flasks per hour with trained operators.
  • User-friendly operation: Simple, repeatable steps designed for fast operator training.

How It Works

  1. Load flasks into the enclosed drum under the mixing blades.
  2. Measure investment and water; close the chamber and start your vacuum pump (not included).
  3. When vacuum is achieved, start the two-speed mixer and set the timer.
  4. Position a flask under the valve, apply vacuum to the lower chamber, and open the valve to pour.
  5. Activate the vibration table under the flasks during the pour.
