St. Louis #82-PT: Professional Platinum & Gold Investment Mixer
The St. Louis #82-PT is a specialized tabletop unit engineered for the high-performance demands of platinum investment mixing. Equipped with a heavy-duty 90W motor, this system is specifically designed to handle the increased viscosity of two-part platinum powders while remaining equally effective for standard gold investment. By consolidating mixing, pouring, and vacuuming into a single workstation, it eliminates the need for separate operations and ensures a high-density, bubble-free mold every time.
Specialized Platinum Engineering
Platinum casting requires precision and power; the #82-PT delivers both through a controlled vacuum environment.
- Heavy-Duty 90W Motor: Optimized for the torque required to mix dense two-part platinum investment powders without stalling.
- Adjustable Speed Control: Fine-tune the rotational speed and set the integrated timer to match the specific chemical setting times of your investment.
- Enclosed See-Through Chamber: Monitor the entire slurry preparation and pouring process through a transparent, vacuum-sealed chamber.
- Adjustable Vibration: The integrated vibration table works simultaneously with the vacuum to ensure investment settles perfectly into the finest details.
Streamlined Operation
Designed for efficiency in busy studios, this unit allows anyone to be trained for professional production in just minutes.
- Graduated Water Cylinder: Includes a precision graduated cylinder for exact water or binder measurement, ensuring the correct ratio for every batch.
- Electronic Flask Alignment: For multi-flask setups, use the electronic turntable to align each flask perfectly under the pouring valve without breaking vacuum.
- Tabletop Efficiency: Industrial-grade performance in a compact footprint suitable for professional jewelry benches.
- Reduced Casting Rejects: Automating the de-gassing and pouring variables eliminates air entrapment and surface defects.
The Professional Workflow
Operation is intuitive: place your flasks in the lower chamber and add the required investment powder. Once the vacuum pump is engaged, open the water/binder valve from the graduated cylinder and start the 90W mixing motor. As the investment fills the flasks, engage the vibration table and electronically rotate the table to fill the next flask. This sealed process ensures that no air is trapped during the critical transition from mixing to pouring.
Coast to Coast Support: Backed by Romanoff International’s extensive technical network, ensuring your high-production casting line remains operational with expert service and training across the country.
