Noida Vacuum Heat Treatment Unit
The Noida Vacuum Heat Treatment Unit, located at Ecotech 11 in Greater Noida, is Lakshmi Vacuum's newest facility — extending our pan-India vacuum heat treatment network to nine locations. It is built to serve the National Capital Region's growing base of aerospace, automotive, and precision engineering customers.
The unit is equipped with modern vacuum hardening and tempering furnaces, following the same process discipline and quality standards as our other facilities across the country.
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 NCR can complete their whole thermal route at one address, on controlled cycles, with the record to match.

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. Because nothing in the atmosphere reacts with the steel, distortion is lower and the result repeats batch after batch - which is what aerospace and precision-engineering drawings demand. It is the workhorse process at our Greater Noida unit and, in most routes, the step before tempering. 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. The result is the balance most drawings ask for: hard enough to resist wear, tough enough to survive shock and fatigue.
Vacuum Annealing
Annealing softens material and removes internal stress before a part is machined or formed, which keeps tool life predictable and dimensions stable on the shop floor. In vacuum the part comes out clean and ready for the next operation instead of needing pickling. It is a common first stop for forgings, castings and bar stock heading for a hardening route. Explore the process →
Vacuum Brazing
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. The vacuum cleans the surfaces as the temperature rises, so the filler flows into tight joints and produces a strong, leak-tight connection. Assemblies come out bright and need no post-braze cleaning. Explore the process →
Vacuum Ageing
Ageing is how strength is reached in aluminium, nickel and other precipitation-hardening alloys: a controlled soak that grows the strengthening phases without the distortion of a quench. Under vacuum the surface stays clean and the properties come out uniform across the batch. It is often the final step that locks in the numbers on the drawing.
Vacuum Stress Relieving
Machining and welding leave stress locked in the material, and that stress is what makes a part move after the last cut. Stress relieving in vacuum releases it, 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. Tooling, gauges and high-precision components benefit most.
Low Pressure Nitriding
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 and case depth is a drawing requirement rather than a suggestion. Explore the process →
Gas Nitriding
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. It suits components where the service load is high and the surface must resist both wear and scuffing.
Vacuum Solutionizing
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. Everything after it - ageing, machining, service performance - depends on this step being clean and even. 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
Vacuum heat treatment means heating and cooling metal inside a chamber with the air taken out. With no oxygen present the surface cannot oxidise or decarburise, so parts come out bright, clean and true to size instead of scaled and out of tolerance. That is why vacuum processing has become the default for aerospace hardware, precision components and tooling, where a finished surface must not be disturbed.
Our Greater Noida unit brings that capability to the eastern side of the National Capital Region - vacuum hardening, tempering, annealing, brazing, ageing, stress relieving, sub-zero treatment, low pressure and gas nitriding, and vacuum solutionizing, all at one address.
Materials and Parts We Treat at the Noida Unit
We treat tool and die steels, alloy and stainless steels including PH grades, nickel and cobalt alloys, aluminium and titanium alloys, copper and brass, and powder-metal or sintered parts.
Typical work arriving at Ecotech 11: aerospace hardware, automotive and transmission parts, precision machined components, moulds and dies, gauge and instrument parts, and brazed assemblies that have to come out clean and leak-tight.
