What You Can Request a Quotation For
One form covers the whole range. Tell us which applies and the team that owns that work picks it up.
Vacuum furnace manufacturing
New vacuum furnaces engineered and built at our Bengaluru works — brazing, sintering, hardening, degassing, carburizing, melting and more, plus custom-built research and pilot systems.
See the 14 product linesCustom-engineered furnaces
Working area, hot-zone material, maximum temperature, vacuum level, quench pressure and control system are matched to your workload — with factory acceptance testing, installation and commissioning.
Furnace range and specificationsVacuum heat treatment as job work
Vacuum hardening and tempering, annealing and solutionizing, brazing, stress relieving and normalizing, high-pressure gas quenching, degassing, low-pressure nitriding and tool steel treatments.
Vacuum heat treatment servicesSpecialized spares & services
Genuine spares and consumables for the furnaces we build — hot zone graphite, ceramics, molybdenum, CFC, seals and gaskets, pump maintenance kits, sensors, valves and machined parts — plus refurbishment and AMC proposals.
Spares and servicesCalibration
Vacuum furnace, thermal equipment, controller, vacuum sensor and pressure and compound gauge calibration — on-site at your plant or in our lab, with ISO 17025 traceability on a sub-contract basis and certificates you can file.
Calibration divisionThermocouples, cables & RTDs
Base metal thermocouples, noble metal Types R, S and B, special-purpose coated and washer-type thermocouples, RTDs, compensation cables, connectors and colour-code references — manufactured in-house.
Thermocouple divisionHow the Quotation Process Works
The form mirrors our internal route: your contact details first, then the requirement.
You send the requirement
Two short steps: contact details, then the furnace type or the process you need. Drawings and specifications travel with the enquiry — PDF, DWG, DOCX or image files up to 10 MB.
Engineering review
Process engineers and metallurgists study the requirement and decide the route, fixturing and quench parameters best suited to the material.
Feasibility, unit and price
You get a clear answer on feasibility, the unit that will run the job, scheduling and price before anything is committed — in writing.
Production and dispatch
Once approved, the job is scheduled and parts are dispatched from the unit nearest you. Every batch follows a documented cycle with recorded parameters and a test report.
What to Include for an Accurate Quotation
The more you can tell us up front, the closer the first quotation will be. Send what you have; we will ask for the rest.
For a new furnace
Working area, hot-zone material (graphite or all-metal), maximum temperature, vacuum level, quench pressure and control system. Because every furnace is engineered to the workload, we quote per configuration.
For a vacuum heat treatment job
Part drawing or sample details, material grade, required hardness or specification, quantity and required delivery date. We treat alloy and tool steels, stainless and PH steels, nickel and cobalt alloys, titanium and aluminium alloys, copper, brass and beryllium copper, and powder-metal and sintered parts.
For spares, calibration or sensors
For spares, send the furnace brand, model and serial number, the part name or a photograph, and the quantity. For thermocouples, send the application or type, temperature range, protection tube, immersion length, quantity and when you need it.

Industries We Quote For
We serve aerospace, automotive, electrical and electronics, tool steel, medical, pharmaceutical and general engineering — with 3000+ satisfied customers globally. Our units also run work for tool and die hardening, energy and power, medical devices, electronics and semiconductor, and research and development. You can see the detail on our industry applications and track record pages.
Nine Vacuum Heat Treatment Units Across India
Vacuum heat treatment runs at nine locations, coordinated with the vacuum furnace manufacturing facility in Bengaluru. Using the unit nearest your plant shortens transit time, and scheduling is confirmed when the enquiry is reviewed. See the unit network or the full list of locations and addresses.
The Quality Behind Every Quotation
Tell us the standard, the specification or the customer requirement at enquiry stage and the cycle, inspection and records are planned around it rather than adjusted afterwards. Cycles are validated to AMS 2750-grade requirements with full traceability, and the instrument chain is calibrated as part of the system. Inspection covers hardness testing (Rockwell, Vickers, micro-hardness), microstructure analysis, non-destructive testing and residual stress measurement, supported by CMM inspection in a temperature-controlled metrology lab. Our quality management system is ISO 9001:2015 certified. More detail is on the quality page, including the calibration division.
