Lakshmi Vacuum Technologies manufactures specialized vacuum strip casting furnaces engineered for the rapid solidification of high-temperature alloys. These advanced systems are critical for producing thin metal strips, amorphous materials, and nanocrystalline alloys used in the aerospace, electronics, and advanced energy sectors.
By induction-melting the alloy under a high vacuum or inert gas atmosphere, our furnaces prevent oxidation and maintain exceptional material purity. The molten metal is then precisely cast onto a rotating, water-cooled copper wheel. This rapid quenching process extracts heat instantly, freezing the microstructure and producing uniform, high-quality thin strips with unique magnetic and physical properties.
Featuring robust induction heating, internal water-cooling systems for the copper wheel, and advanced PLC interfaces with touchscreen HMIs, our strip casting furnaces offer precise control over strip thickness, width, and microstructure. Whether for R&D or small-scale production, our systems deliver reliable, high-purity results.
