The 25kW Vacuum Gold Bar Casting Machine is a high-performance, industrial-grade solution designed for precise and defect-free casting of gold and other precious metal bars. Engineered for continuous production environments, this machine combines powerful induction heating with advanced vacuum technology to deliver dense, smooth-surface bars with minimal porosity and oxidation.
Equipped with a 25kW high-frequency induction power supply, the machine ensures fast and uniform melting of gold, silver, copper, and alloy metals. The integrated vacuum casting chamber removes trapped gases during pouring, resulting in superior bar quality and consistent weight accuracy. This makes it ideal for refineries, bullion manufacturers, mints, and large jewelry production units.
The system features a robust water-cooled induction coil, heavy-duty graphite crucible compatibility, and a precision-controlled pouring mechanism for safe and repeatable operation. A PLC-based control panel allows operators to monitor temperature, power, and vacuum levels with ease, reducing human error and increasing productivity.
Built with a strong MS/SS body and high-quality electrical components, the 25kW Vacuum Gold Bar Casting Machine offers long service life, low maintenance, and reliable performance even under demanding industrial conditions.
