KWS Investment Mixing Machine: 30 kg Capacity / 8-Flask System

The KWS Investment Mixing Machine is a versatile high-capacity system designed to bridge the gap between boutique designer studios and high-output industrial casting houses. Capable of mixing up to 30 kg of investment compound under a full vacuum, this machine allows for the simultaneous filling of up to 8 flasks. Engineered for precision, the KWS system ensures that every mold produced features a high surface quality and sharp contours, significantly reducing post-casting cleanup and rejection rates.

Advanced Process Control

Achieve professional-grade results through a controlled environment that prioritizes metallurgical integrity and bubble-free filling.

  • Variable Speed Mixing: Features a fully adjustable mixer speed to ensure the correct setting for every type of investment powder and process requirement.
  • Vacuum with Vibration: Combines powerful vacuum suction with integrated vibration to ensure a dense, precise, and bubble-free fill every time.
  • Visual Monitoring: A heavy-duty Plexiglass lid allows the operator to monitor the entire mixing and pouring process in real-time.
  • High-Definition Casting: Specifically engineered to produce sharp contours and superior surface finishes, even when processing small quantities.

Built for the Production Floor

Maintenance and longevity are at the core of the KWS design, featuring corrosion-resistant materials and smart filtration systems.

  • Corrosion Protection: All critical components are manufactured from stainless steel or aluminum to resist the harsh environment of water and gypsum exposure.
  • Pump Protection: Includes a specialized vacuum pump filter system designed to catch debris and moisture, significantly extending the life of your pump.
  • Special Alloy Taps: Filling taps are crafted from a proprietary alloy that resists damage and buildup from gypsum and water.
  • Rapid Servicing: Uses long-lasting gaskets (2–3 year lifespan) that can be replaced quickly without the need to dismantle the entire unit.

Simplified Operation & Cleaning

The KWS system is designed to provide a clean and pleasant working environment. For post-production maintenance, the mixer swivels effortlessly over a dedicated drain bowl, allowing the entire tank to be rinsed with an integrated spray nozzle. This rapid-clean design minimizes downtime between batches and prevents investment buildup. With its 30 kg capacity and 8-flask turntable, this machine represents a significant upgrade for any shop looking to scale their production without compromising on the fine details of their jewelry or industrial components.

Technical Support: Romanoff International ensures your studio setup remains operational with expert service and training from coast to coast.
