• ELIMINATE BUBBLES WITH VACUUM INTEGRATION – Unlike standard furnaces that leave castings with porosity and burrs, this 3-in-1 unit integrates a powerful 1/3HP, 4CFM vacuum pump directly into the base. The suction casting system effectively removes air pockets from the molten metal and mold, ensuring high-density, smooth-surfaced jewelry results specifically for professional lost wax casting
• 1500W RAPID MELTING POWER – Built for efficiency. While competitors lag at 1400W, our upgraded 1500W heating element reaches a maximum temperature of 2102°F (1150°C) significantly faster. Combined with the high-thermal-conductivity graphite crucible, it melts 2kg (4.41 lbs) of gold, silver, or copper in record time, streamlining your production from scrap to ingot
• PRECISE PID INTELLIGENT CONTROL – Stop guessing temperatures. The machine features an advanced PID digital control system that maintains heat within a narrow error margin of ±5°C. The intuitive pressure gauge and adjustment lever allow you to monitor vacuum levels in real-time, giving you total control over the casting environment for repeatable, professional-grade quality
• HEAVY-DUTY & SAFETY DESIGN – The body is constructed from durable iron and aluminum with a heat-resistant spray finish, while the vacuum hood uses thick aerospace-grade acrylic to withstand pressure. A protective steel bell and rubber pad ensure a tight seal during suction, preventing leaks and ensuring safe operation for freestanding installation
• VERSATILE FOUNDRY SOLUTION – A complete workshop in one device. Ideal for jewelry factories, art studios, and DIY hobbyists recycling scrap metal. It expertly handles gold, silver, lead, copper, brass, and bronze. Whether creating intricate rings, pendants, or casting simple bullion nuggets, this machine reduces defects and polishing time
