Jewelry Vacuum Pressure Gold Platinum Casting Machine

Dual Chamber Application

Fully automatic vacuum jewelry casting machine adopts a revolutionary new dual chamber concept. Its melting chamber and casting chamber are completely independent. When casting, the machine can control the injection of metal into the mold by applying a pressure difference during the pouring process.

Creates a high vacuum environment for jewelry casting under a pressurized pressure of 10 – 120 kPa. Precious metals will not contact air to cause oxidation, and the cast jewelry will be free from bubbles, pores, and defects.

PID temperature control panel maintains temperature accuracy within ±1 °C.
Mitsubishi PLC human–machine interface enables one-click fully automatic operation.

The casting chamber uses air‑pressure automatic lifting, convenient for loading/unloading castings. This increases chamber volume and pressure, significantly enhancing casting results.

Max temperature: 2100 °C.
At 1600 °C can cast gold, silver, and other low‑temp metals.
At 2100 °C can cast high‑temp refractory metals like platinum, palladium, and rhodium.
