Hosur Facility
We at Lakshmi Vacuum offer various vacuum heat treatment solutions and services. Along with efficient metallurgists with continual improvement on process and the furnace by coordinating with customers as well as various experts to provide better service on vacuum heat treatment in the market.
With sophisticated automated in-house laboratory and fully automated vacuum heat treatment furnaces, our Hosur unit delivers precision thermal processing for diverse industrial applications across South India.
The Hosur unit is IATF 16949 certified, backed by an ISO-aligned quality system, in-house metallurgical laboratory and documented process control for automotive supply chains.
Infrastructure
State-of-the-art vacuum heat treatment facility equipped with fully automated controls, in-house laboratory, and precision inspection capabilities.
Service Centre Entrance
Our Hosur service centre at Sidco 3rd Phase, Zuzuvadi, welcomes customers for direct consultation, job processing, and component pickup. The facility is designed for easy access for delivery vehicles and walk-in customers, with dedicated reception and metallurgical consultation areas where engineers review drawings, discuss process routes, and confirm hardness specifications before any job is committed.
Inspection Facility & Equipment
Our in-house inspection laboratory is equipped with Rockwell, Vickers, and micro-Vickers hardness testers for surface and case-depth measurement, metallurgical microscopes for microstructure analysis and retained-austenite quantification, and dimensional metrology equipment to verify post-treatment geometry. Tensile testing and grain-size analysis capabilities allow us to validate mechanical properties against customer specifications. Every batch leaves with documented evidence that the thermal cycle met the metallurgical requirement.
Dies Processed at LVH Hosur
Dies processed at our Hosur unit come out bright, clean, and dimensionally stable — ready to go straight back into production. The images show typical vacuum-hardened and tempered dies with oxide-free surfaces, controlled distortion, and repeatable hardness batch after batch. The close-up view highlights the surface finish that vacuum processing delivers without any post-treatment cleaning or pickling required.
Vacuum Heat Treatment Services
We specialize in a wide range of vacuum heat treatment services at our Hosur unit at Sidco 3rd Phase, Zuzuvadi.
Vacuum Hardening
Bright, scale-free hardening run on fully automated vacuum furnaces for tool steels and engineering components — lower distortion, repeatable batch after batch.
Vacuum Tempering
Tempering straight after hardening to relieve internal stress and hold the specified hardness — running it under vacuum keeps the surface clean.
Vacuum Annealing
Controlled atmosphere annealing for stress relief, grain refinement, and improved machinability — parts come out bright and clean, ready for the next operation.
Vacuum Solutionizing
Takes stainless and superalloy parts to the right temperature in vacuum to dissolve alloying elements, then quenches them into a uniform starting structure — oxide-free surface with chemistry matching the core.
Vacuum Aging
A controlled soak that grows the strengthening phases in aluminium, nickel and other precipitation-hardening alloys without the distortion of a quench — surface stays clean and properties come out uniform.
Vacuum Stress Relieving
Removes residual stresses from machining, forming and welding so dimensions hold through grinding, fitting and assembly — vital for long or thin parts.
Vacuum Brazing
Clean, flux-free joints for metal assemblies — heat exchangers, sensor bodies, tool assemblies — with excellent strength and corrosion resistance.
Vacuum Precipitation Hardening
Age-hardening vacuum heat treatment for precipitation-strengthened alloys to achieve peak mechanical properties — controlled soak that grows the strengthening phases for maximum strength and toughness.
Sub-Zero Treatment
Treats metals below zero to complete retained-austenite transformation, stabilising size and improving wear life — tooling, gauges and high-precision components benefit most.
And many other specialized heat treatment processes.
