Overview
Induction melting furnaces
ENRX Induction metal melting systems provide high-efficiency, safe, and clean melting solutions for a wide range of metals including ferrous and non-ferrous alloys. All systems are powered by ENRX advanced Sinac converters (IGBT or thyristor), offering high uptime, automatic load matching, and excellent energy efficiency. The product range includes:
- FIB – Single-axis tilting furnaces for capacities up to 6,000 kg, featuring high-efficiency coil design and easy-change crucibles or rammed linings.
- DAB – Dual-axis tilting furnaces ideal for precision casting applications with optional inert-gas lids and capacities up to 300 kg (ferrous/copper alloys) or 100 kg (aluminum/silicon).
- FIM – Moving-coil furnaces designed for precious metals (gold, silver), copper, bronze, and aluminum alloys. The static crucible design avoids contamination.
- LAB – Laboratory melting furnaces for education, research, and sample casting with capacities from 7 to 40 kg, available with manual or hydraulic tilting.
- FAR – Roll-over furnaces offering 180° tilting, ideal for investment casting with high-power converters to minimize oxidation.
These systems can be customized for vacuum melting, glass melting, graphite coating and other specialist applications.
The process supports a wide range of brazed joint types—such as butt, lap and tube joints—and is applicable to metals including copper, brass, aluminum, steel, stainless steel, nickel alloys, hard metals, carbides and noble metals. Induction systems can be compact handheld Minac units, stationary Sinac generators, or fully customized automated brazing machines with robotics, controlled atmospheres and advanced process monitoring. ENRX provides complete brazing solutions covering system design, coil engineering, controlled atmosphere brazing, automated loading/unloading, precision filler feeding, flux management and quality control. Applications span electricity generation, automotive, HVAC, tools, appliances, aerospace and specialist manufacturing sectors
