Chennai Facility
The Chennai unit runs from Plot No. 8, Aerospace Park, Vallam Vadagal, Sriperumbudur, under Lakshmi Vacuum Services Pvt. Ltd. That address places it inside Tamil Nadu's automotive and heavy-engineering belt, minutes from the Sriperumbudur and Oragadam corridors.
Vacuum processing means no oxygen at the surface, so components come out bright, clean and true to size. The unit runs vacuum hardening, tempering and brazing for tooling, transmission components and press-shop dies, backed by an automated in-house laboratory.
Vacuum Heat Treatment Services
Vacuum Hardening
Oxygen-free hardening for tooling, dies and transmission parts, bright and dimensionally stable with repeatable hardness.
Explore process →Vacuum Tempering
Runs straight after hardening to relieve internal stress and hold the specified hardness without brittleness.
Vacuum Brazing
Flux-free, leak-tight joints in one clean furnace cycle, with no post-braze cleaning or scale to remove.
Explore process →Age Hardening
Builds peak strength in age-hardenable alloys through a controlled soak, without quench distortion.
Dewaxing & Sintering
Integrated binder removal and high-temperature sintering for powder-metal and MIM components.
Explore process →One address, the whole thermal route: tooling, transmission components and press-shop dies from the Sriperumbudur and Oragadam corridors complete every step on controlled cycles, with the record to match.
Infrastructure
An automated in-house laboratory and fully automated vacuum heat treatment furnaces sit behind every batch processed at Sriperumbudur.
The equipment is the same class of vacuum furnace that Lakshmi Vacuum builds for its own units and for customers. Process parameters are recorded and repeatable, which is what keeps hardness and case depth consistent across repeat orders.

Which processes run at the Sriperumbudur unit?
Vacuum hardening, vacuum tempering, vacuum brazing, age hardening, and integrated dewaxing and sintering for powder-metal components.
Do you treat tooling and press-shop dies in Chennai?
Yes. Vacuum hardening and tempering return moulds, press-shop dies, blanking dies and cutting tools to production with bright, scale-free surfaces and stable dimensions, on just-in-time schedules.
What do I need to send for a quotation?
Part drawing or sample details, material grade, required hardness or specification, quantity and required delivery date are enough for us to quote.
Which industrial corridors does the Chennai unit serve?
The unit serves Sriperumbudur, Oragadam, Vallam Vadagal and Ambattur, along with customers across Chennai and the wider Tamil Nadu manufacturing belt.
Is vacuum brazing available in Chennai?
