This Romanoff KWS investment mixing machine can mix up to 70 kg of investment powder and is also suitable for smaller output capacity (designer studios). This machine can hold 8 flasks at a time. This machine uses the standard voltage available in 220/60/3.


  • - High-quality casting with a minimum amount of work
    The Romanoff KWS EB5 investment machine tabletop is designed to mix 70 kg of investment compound under vacuum and to simultaneously fill 8 flasks.
  • - High surface quality and contour sharpness on castings
    It is now also possible to produce smaller quantities of castings with high surface quality and contour sharpness.
  • - Pleasant and clean work through simple operation
    This mixer is simple to operate and ensures a clean and pleasant working environment. The variable speed mixer guarantees that the correct rotational speed for the specific investment process can be selected at all times. Drive motor and mixing chamber are fixed to each other. This construction avoids the malfunction of the machine.
  • - Minimum maintenance needed to maintain the mixer
    All parts of the machine are made of stainless steel or of aluminum (Al). This results in minimum maintenance as well as wear and tear. To protect the vacuum pump a filter-system has been installed which improves the life cycle of the pump substantially. The filling taps are made of a special alloy that is not affected by gypsum and water.


Technical Details
  1. 1. 8 flasks are placed in the mixer and the stirring unit is swiveled over them.
  2. 2. An adequate measured quantity of water is poured into the stirring container.
  3. 3. The weighed investment material is filled into the stirring container. The mixer is sealed with a plexiglass lid which allows surveillance of all procedures. Now the investment material is mixed with the water under a vacuum. Through the opening of the filling taps, the underneath placed flasks are filled while still under vacuum. This procedure and simultaneous vibration allow flasks of the highest quality to be produced.
  4. 4. To clean the machine the mixer is swiveled over the drain bowl and then cleaned with a spray nozzle.

  • - Filtering system for the protection of the vacuum pump improves the life cycle of the pump substantially.
  • - The taps are made of a special alloy that is not affected by gypsum and water. 
  • - Gaskets which are affected by the corrosiveness of the gypsum and are used daily, have a life cycle of 2 - 3 years. Through loosening two screws they can be removed for maintenance or replacement (no dismantling). 
  • - Perfect protection against corrosion since all parts are made of aluminum (Al) or stainless steel.
