Mumbai Vacuum Heat Treatment Unit
The Mumbai Vacuum Heat Treatment Unit, located in Vasai East (Dist. Palghar), began operations in Kandivali before shifting to its current, expanded plant. It serves the region's dense base of tooling, die-making, and general engineering customers with precise, distortion-free thermal processing.
Operating on a 24x6 schedule (with Sundays as our weekly maintenance day), the Mumbai unit delivers unparalleled technical expertise in heat treating various toolings, ensuring rapid turnaround and just-in-time deliveries.
Infrastructure
State-of-art vacuum hardening and tempering furnaces for just-in-time deliveries.
Plastic moulds, pressure die-casting dies, forging dies, sheet-metal stamping and blanking dies, tablet toolings and blades or cutters for a range of industries — the plant runs state-of-the-art vacuum hardening furnaces and vacuum tempering furnaces so that tooling goes back into production on just-in-time schedules rather than waiting in a queue.
The same unit also runs vacuum brazing, ageing, stress relieving, sub-zero treatment, low pressure and gas nitriding, and vacuum solutionizing — which means aerospace hardware, automotive parts and precision components from across the Maharashtra region can complete their whole thermal route at one address, on controlled cycles, with the record to match.
Vacuum Heat Treatment Services
Comprehensive vacuum heat treatment processes for toolings across industries.
Vacuum Hardening
Hardening in a vacuum furnace heats the part in an oxygen-free chamber, so the surface stays bright and free of scale and the part comes out dimensionally stable. Distortion is lower and the result repeats batch after batch. It is the workhorse process at our Vasai East unit. Explore the process →
Vacuum Tempering
Tempering follows hardening and takes the brittleness out of a freshly hardened part while holding the hardness you specified. Running it under vacuum keeps the surface clean, so nothing gained in hardening is lost.
Vacuum Annealing
Softens material and removes internal stress before a part is machined or formed, keeping tool life predictable and dimensions stable. A common first stop for forgings, castings and bar stock heading for a hardening route. Explore the process →
Vacuum Brazing
Joins an assembly in a single clean furnace cycle — heat exchangers, sensor bodies, tool assemblies, multi-part stacks — with no flux and none of the corrosive residue flux leaves in internal passages. Assemblies come out bright and need no post-braze cleaning. Explore the process →
Vacuum Ageing
A controlled soak that grows the strengthening phases in aluminium, nickel and other precipitation-hardening alloys without the distortion of a quench. Under vacuum the surface stays clean and properties come out uniform across the batch.
Vacuum Stress Relieving
Releases the stress locked in by machining and welding, so geometry holds through grinding, fitting and assembly. On long or thin parts — shafts, plates, weldments — it is the difference between a component that measures true and one that keeps drifting.
Sub-Zero Treatment
After hardening, some retained austenite never transforms on its own, and it keeps changing dimensions long after the part was measured. A sub-zero cycle takes the part below zero to complete that transformation, stabilising size and improving wear life.
Low Pressure Nitriding
Gives close control over case depth and surface quality by running the process at reduced pressure, cycle after cycle. That repeatability is what production lines need when the same part is treated week after week. Explore the process →
Gas Nitriding
Builds a deep, hard case with strong load-bearing support underneath — the combination that lets heavily loaded parts keep running instead of breaking down at the surface. Suits components where service load is high and the surface must resist wear and scuffing.
Vacuum Solutionizing
Takes stainless and superalloy parts to the right temperature in vacuum to dissolve the alloying elements, then quenches them into a uniform starting structure. Because it runs in vacuum, the surface stays oxide-free and the chemistry at the surface matches the core.
What Vacuum Heat Treatment Does for Your Part
Heat and cool metal inside a chamber with the air taken out. No oxygen means no oxidation, no decarburisation — parts come out bright, clean and true to size.
Bright, Clean Surfaces
No scale, no decarburisation — parts come out ready for the next operation.
Dimensionally Stable
Controlled atmosphere means lower distortion and repeatable geometry batch after batch.
