Lakshmi Vacuum Technologies manufactures high-purity vacuum melting furnaces engineered for the processing of reactive and refractory alloys. Our systems are available in two primary configurations: Vacuum Induction Melting (VIMF) and Vacuum Arc Melting (VAMF), catering to the stringent demands of the aerospace, medical, and advanced metallurgical industries.
By performing the melting process under a high vacuum or inert gas atmosphere, our furnaces prevent oxidation and contamination, ensuring exceptional material purity and mechanical properties. These systems are indispensable for melting superalloys, titanium, zirconium, and other advanced materials.
Equipped with advanced PLC/SCADA control systems, our furnaces offer precise control over temperature, melting rates, and vacuum stability, delivering repeatable, high-integrity ingots or castings for mission-critical applications.
