Precision Contract Manufacturing in India — Since 1997
Radiant Precicom Industries Pvt. Ltd. is a Mumbai-based, ISO 9001:2015 certified precision contract manufacturer with over 25 years of experience supplying safety-critical and high-tolerance components to Indian Railways, defence, oil & gas, automotive, crane, and infrastructure sectors. Our 3-acre manufacturing facility produces 5,000+ precision parts per month across CNC machining (3-axis and 4-axis), press shop fabrication up to 200 tonnes, plasma and oxy-fuel cutting, SS pipe & tube forming, gear hobbing, and sub-assembly operations.
As a major approved supplier to Indian Railways, we manufacture master controllers, VCB damper sub-assemblies, and air-suspension components to RDSO specifications. Our product range includes rail clamps, crane components, spring buffers, custom worm gearboxes, raising & lowering systems for high-mast lighting poles, custom door hinges, and stainless steel tubes (ASTM A269/A312, grades 304/316). We export to Saudi Arabia and serve 20–30 active clients including large public sector undertakings.
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.
