How did Lakshmi Vacuum start?
Lakshmi Vacuum began in 2003 as a vacuum heat treatment service in Bengaluru, when the technology was new to India. It later added vacuum furnace manufacturing, spares and service, and thermocouple calibration.
What vacuum furnaces does Lakshmi Vacuum manufacture?
The range has 14 product lines: vacuum brazing, sintering, hardening, degassing, carburizing and melting furnaces, vacuum ovens, autoclaves, thermo-vacuum simulation chambers, vacuum hot presses, low-pressure nitriding, vacuum strip casting, pack aluminizing furnaces and rare earth magnetic mineral processing equipment.
What is a thermo-vacuum simulation chamber (TVAC)?
A TVAC reproduces the high vacuum and extreme temperature cycling of space on the ground. Lakshmi Vacuum builds TVAC chambers that reach 5×10⁻⁶ mbar with LN₂-cooled thermal shrouds, used to qualify satellites, payloads and flight hardware.
Does Lakshmi Vacuum make equipment for rare earth magnet processing?
Yes. Lakshmi Vacuum manufactures rare earth magnetic mineral processing furnaces for NdFeB and SmCo materials, along with vacuum strip casting and vacuum sintering furnaces used in rare earth magnet production.
What is vacuum heat treatment and why use it?
Vacuum heat treatment heats metal parts inside a vacuum chamber, so there is no air to cause oxidation or decarburisation. It gives clean, bright parts, uniform heating with controlled cooling to limit distortion, and programmed cycles that repeat from batch to batch.
Can I get vacuum heat treatment done without buying a furnace?
Yes. Our vacuum heat treatment centres across 9+ locations in India process your components on our own furnaces.
Do you service furnaces made by other manufacturers?
Yes. We offer genuine spares, service and annual maintenance contracts for every furnace we build, and for third-party vacuum furnaces too.
Do you deliver vacuum furnaces outside India?
Yes. Lakshmi Vacuum has delivered furnaces to customers in 10+ countries, with installation, commissioning and operator training handled by our own team.
What is the Versatreat range?
Versatreat is Lakshmi Vacuum's range of vacuum furnaces. New features are validated through six months of on-site trials before they are introduced into the range.
Which industries use Lakshmi Vacuum furnaces?
Aerospace, space, automotive, tooling, medical implants, powder metallurgy, rare earth magnets, specialty alloys, composites and ceramics, surface engineering, electronics and research institutions.
