Unimech Aerospace

What Unimech Aerospace does

Unimech Aerospace is an Indian precision engineering and contract manufacturing company, founded in 2016 in Bengaluru and publicly listed on Indian stock exchanges under the ticker UNIMECH. The company operates three facilities in the Hi-Tech Defence and Aerospace Park near Bengaluru — a registered and corporate office with a precision engineering unit, the Innomech Aerospace Toolings manufacturing facility in the Aerospace SEZ, and a separate fabrication unit — collectively spanning 270,000 sq.ft. with 155+ CNC machines and temperature-controlled environments. It serves four verticals: aerospace, defense, energy (including nuclear and gas turbine), and semiconductors, with named customers including global aerospace OEMs, defense organizations, NPCIL for nuclear power systems, power generation OEMs, and semiconductor equipment manufacturers across India, the UK, Europe, the USA, and (via a 2026 JV) Saudi Arabia.

The core technology stack is built around high-precision CNC machining with 5-axis capability, advanced metrology (CMM, VMS, contour measurement), and a proprietary in-house ERP platform that integrates quotation through final inspection with real-time monitoring. Manufacturing tolerances of ±5 microns for positional accuracy, 10 microns for flatness/parallelism, and 8 microns for runout support the company's positioning in build-to-print and build-to-specification contracts. Capabilities extend across 3/4/5-axis machining, HMC, VMC, turn-mill, surface grinding, multiple welding processes (TIG, MIG, GTAW, GMAW, SMAW), assembly, and in-house testing. Quality credentials include AS9100D, NADCAP, ISO 9001:2015, ISO 14001, ISO 45001, and Cyber Essentials certifications; the recently acquired Hobel Bellows facility additionally holds IATF 16949:2016.

The business model is B2B project-based contract manufacturing: revenue is generated through quote-based, multi-year contracts for precision components, aero tooling, ground support equipment, and turnkey electromechanical systems (notably nuclear). Pricing is customized to part complexity, tolerance, material, and volume rather than standardized tiers. The customer mix is dominated by enterprise and government buyers with long qualification cycles — the company has completed over 200 first-article qualifications. Recent strategic actions include a Rs 250 crore Steadview Capital-led private equity round (July 2024), a 51%-controlled JV with YBAK in Saudi Arabia (January 2026, ~$30 million phased investment), and the Rs 450 crore Hobel Bellows acquisition (April 2026), alongside a tripling of the consolidated order book to Rs 314 crore as of May 2026.
