ALMAS Releases New 1KG Full-auto Vacuum Pressure Casting Machine – Reliable Casting Equipment for Gold & Silver Jewelry
2026/10/02
Key Product Features
1. Fully Automatic Vacuum & Pressure Casting Integration
This 1KG vacuum pressure casting machine combines vacuum melting and pressure casting in one unit. It creates an oxygen-free melting environment to effectively prevent metal oxidation, eliminating pores, inclusions and discoloration on cast jewelry surfaces. With automatic pressure filling, molten metal can fully flow into every detail of gypsum molds, delivering smooth and high-density castings for intricate jewelry designs.
2. Dual Thermocouple Temperature Monitoring & Precise Temperature Control
Equipped with two thermocouple types: K type for up to 1150°C and R type supporting 1450°C high temperature measurement. It can accurately monitor real-time melting temperature for gold, silver and copper. Stable temperature control avoids overheating or insufficient melting, guaranteeing consistent metal fluidity and reducing casting failure rates for jewelry workshops.
3. Compact Body with 1KG Melting Capacity
The machine supports maximum 1KG metal melting, perfectly suited for small-to-medium batch jewelry casting for rings, pendants, bracelets and custom ornaments. The integrated design occupies minimal workshop space. It is ideal for independent goldsmith studios, small jewelry factories and jewelry repair workshops.
4. Stable Power & Robust Construction
Working under 220V / 50Hz single-phase power supply with 4KW power output, it fits common workshop power grids without extra modification. The solid frame structure ensures stable operation during high-temperature melting and pressurized casting. The total weight of 95KG reduces machine vibration, keeping production stable for long continuous working hours.

Why This Matters for Jewelry Manufacturers
Vacuum pressure casting is the core step in lost wax jewelry production. Traditional manual casting often brings air bubbles, shrinkage cavities and low finished yield. ALMAS’s new fully automatic vacuum pressure casting machine simplifies the casting workflow, lowers technical requirements for operators, and greatly improves casting quality and yield.
Whether you own a small goldsmith workshop, medium jewelry studio or jewelry casting factory, this machine meets daily demands for custom jewelry, mass production of gold/silver ornaments and copper art casting.
Paired with ALMAS full jewelry equipment lineup including jewelry 3D printers, wax injector, polishing machines and laser welders, ALMAS supplies complete one-stop jewelry manufacturing solutions for global jewelry businesses.
