Precision Contract Manufacturing in India — Since 1997
Radiant Precicom Industries Pvt. Ltd. is a Mumbai-registered, Daman-based, ISO 9001:2015 certified precision contract manufacturer with 29+ years of experience supplying safety-critical and high-tolerance components to Indian Railways, defence, cranes & material handling, oil & gas, and steel & infrastructure sectors. Our 1,31,000 sq. ft. (3-acre) Daman facility produces 5,000+ precision parts per month across CNC turning (up to Ø1000 mm), 3 & 4-axis milling (up to 1250 × 600 × 600 mm), press shop fabrication, plasma and oxy-fuel cutting, gear hobbing up to module 6, and sub-assembly operations across 34+ installed machines.
As an approved supplier to Indian Railways, we manufacture master controllers, earthing switches, and VCB damper sub-assemblies to RDSO specifications. Our product range includes worm gearboxes, gears/sprockets/ pulleys, locking assemblies, brass & SS pipe fittings, SS flanges, and crane & rail components. We export 65% of production — primarily to the Gulf, with expansion underway to Germany, Canada, and the USA — and serve 20–30 active clients including Rail Wheel Factory, Integral Coach Factory, BHEL, Konecranes, Jindal Steel, and Larsen & Toubro.
Every component is manufactured under a documented quality management system with full material traceability, in-process inspection, hardness testing (Rockwell/Brinell), dimensional metrology, and calibrated gauges. Our mechanical design team uses SolidWorks and MasterCAM to support design-to-delivery programmes and build-to-print contracts.
