Machine configuration, cooling equipment and optional temperature and touchscreen controls.
The matching water chiller supplies stable cooling for the induction coil and power system during melting and casting.
Optional infrared measurement provides non-contact temperature monitoring for high-temperature metal casting.
The optional Siemens PLC touchscreen displays operating data, workflow settings and machine status.
The machine melts the metal under vacuum and transfers it into the flask by controlled centrifugal force.
Confirm these supporting requirements when planning installation of the platinum centrifugal casting machine.
Cooling water pressure should be at least 0.2 MPa to protect the induction coil and power system.
View water chillers →Air pressure of approximately 0.4–0.8 MPa is required for automatic furnace-lid operation.
Prepare argon or nitrogen supply for vacuum-protected melting and casting.
Quartz crucibles, flasks and investment powder should match the metal, batch size and casting process.

Feature of centrifugal vacuum casting machine:
Centrifugal vacuum casting machine coil rise and fall controlled by operation panel
After metal completely melted in a vacuum, the metal comes out of the crucible by spinning and into the flask.
Specially designed for small volume platinum, palladium, stainless steel casting
A: This machine is specifically designed for casting high-grade jewelry and is perfectly suited for various precious metals and alloys, including stainless steel, platinum, palladium, Karat gold, and silver.
A: The designed capacity range for this machine is between 300 grams and 1 kilogram, making it highly suitable for small to medium-batch jewelry production.
The common standard flask size is φ 3.5 x 4 inches. To accommodate diverse production needs, we support customization of other, larger flask sizes, such as φ 5 x 7 inches.
Please refer to the specification parameters for specific machine models for precise capacity, or inquire about custom machine options.
A: Vacuum Centrifugal Casting involves conducting both the metal melting and pouring processes within a vacuum chamber. Subsequently, centrifugal force generated by high-speed rotation propels the molten metal from the crucible at high velocity, forcing it to fill every intricate detail of the investment mold, ensuring sharp definition and defect-free castings.
A: *Superior Mold Filling Power and Feeding Capability: Centrifugal casting holds a natural advantage for components requiring extreme density and superior mechanical properties.
*Ideal for Highly Reactive and High-Melting-Point Metals: Such as platinum, palladium, and stainless steel.
*Higher Casting Purity, Better Inclusion Control: Due to density differences, inclusions tend to be pushed towards the casting’s inner surface by centrifugal force, making them easier to remove during subsequent machining.
*Smoother Mold Filling, Lower Risk of Gas Entrapment: The laminar flow filling characteristic of centrifugal casting promotes smooth surfaces and minimizes gas porosity in the castings.
A: The machine utilizes a #100 type vacuum pump, capable of achieving a vacuum level of 0.1 MPa. The maximum rotation speed is steplessly adjustable from 0-700 rpm.
A: Infrared temperature measurement control and a Siemens PLC touchscreen control system are available as optional features.
A: It is equipped with a latest-generation Japanese transistorized medium-frequency generator with continuously adjustable output power, this centrifugal casting machine achieves high production efficiency of 4-5 minutes per batch (melting time approximately 1-3 minutes, centrifugal casting time approximately 1-2 minutes).
A: Yes, you will also need a water chiller, an air compressor, and an inert gas supply:
Water Chiller: Required for cooling the machine’s induction coil to prevent overheating. Water pressure requirement is ≥ 0.2 MPa.
Air Compressor: Needed for the automated opening and closing of the machine lid. Required air pressure range: 0.4 – 0.8 MPa.
Inert Gas: Argon or Nitrogen can be used.
A: The main consumables for this machine are quartz crucibles, investment powder, and flasks. Quartz crucibles are fragile items subject to high wear; their typical service life is around 2-5 uses. The specific service life depends on the customer’s operating environment and daily maintenance practices.
A: Applying vacuum serves two core purposes:
① Prevents Metal Oxidation: Precious metals in a molten state are highly reactive and readily form oxide slag when exposed to oxygen, compromising casting quality and aesthetics. The vacuum environment eliminates this issue.
② Removes Gases from the Plaster Mold: Evacuating the air removes gases trapped within the investment mold surrounding the wax tree, ensuring the molten metal perfectly replicates the finest details and avoiding gas porosity in the final castings.
A: After casting is finished, use tongs to remove the flask. Then, submerge the entire flask in water for “quench cleaning.” The investment mold will disintegrate upon contact with water, revealing the casting tree inside. Finally, cut the individual castings from the sprue and proceed with subsequent finishing steps, like polishing.
A: *Cleaning: After each use, thoroughly clean any spilled metal debris and investment material, especially from the centrifugal arm and bearing areas.
*Consumable Replacement: Monitor the condition of quartz crucibles and replace them promptly when needed.
*Vacuum Pump: Regularly check the vacuum pump oil level and oil condition. Change the oil according to the manufacturer’s schedule to maintain specified vacuum levels.
*Rotating Components: Periodically inspect the balance of the rotation arm and the flexibility of the release mechanism. Lubricate bearings as appropriate.
*Electrical System: Keep the equipment dry and clean. Regularly inspect power cords and connections.
