The KWS EB-10/16 investment mixing machine (220 V/3 PH/60 Hz, no vacuum) is used to blend large batches of investment material for mold preparation in casting workflows where vacuum degassing isn’t required. Its robust, high-capacity design supports efficient mixing of up to 10–16 flasks or equivalent volume, helping produce consistent, lump-free slurries for detailed molds.

Romanoff KWS EB5: Precision Tabletop Vacuum Investing System
The Romanoff KWS EB5 is a high-performance investment mixing machine designed for jewelry manufacturers who require industrial-grade precision in a compact, tabletop footprint. Whether you are running a high-output production line or a specialized designer studio, the EB5 offers the flexibility to mix up to 16 kg of investment powder. Engineered for maximum efficiency, this system allows you to achieve exceptional surface quality and contour sharpness with a minimum amount of manual labor.
Key Performance Features
The EB5 integrates advanced vacuum mixing technology to eliminate air bubbles and ensure the structural integrity of every flask.
- 6-Flask Capacity: Capable of holding and filling up to 6 flanged flasks simultaneously for streamlined production.
- Vacuum Mixing Technology: Both mixing and flask filling occur under a full vacuum to prevent air entrapment and surface defects.
- Variable Speed Control: Features an adjustable mixer speed, allowing you to select the exact rotational speed required for your specific investment process.
- Simultaneous Vibration: Filling occurs under simultaneous vibration and vacuum, allowing for the highest-density flasks and sharpest detail.
Durable Construction
Built for longevity and minimal maintenance, all critical components are manufactured from premium, corrosion-resistant materials.
- Corrosion Protection: All parts are made of stainless steel or aluminum (Al), resulting in minimum wear and tear.
- Pump Protection: An integrated filter system protects the vacuum pump, substantially extending its industrial life cycle.
- Specialized Alloy Taps: Filling taps are crafted from a unique alloy that is completely resistant to the corrosive effects of gypsum and water.
- Easy Gasket Service: Corrosive-resistant gaskets typically last 2 to 3 years and can be replaced by loosening just two screws—no full dismantling required.
Technical Process & Operation
The Romanoff KWS EB5 is engineered for a "clean-room" experience with a simple, intuitive workflow. To operate, place up to 6 flanged flasks in the mixer and swivel the stirring unit into position. Add measured water and weighed investment material into the stirring container and seal with the transparent Plexiglass lid for full surveillance of the mixing process. Once mixed under vacuum, open the filling taps to fill the flasks. After the cycle, simply swivel the mixer over the drain bowl and clean using the integrated spray nozzle.
Professional Quality: The EB5 provides a clean and pleasant working environment, ensuring that even smaller quantities of castings meet the highest industrial standards for contour sharpness.
