Precision Railway Components Manufacturing
Metal Craft is a trusted, long-standing supplier of high-precision electrical components engineered specifically for Indian Railways, Metro Rail networks, and traction OEMs. Backed by 50+ years of metallurgical expertise, we manufacture high-conductivity ETP copper busbars, traction motor contact links, pantograph contact strips, locomotive switchgear terminals, transformer clamping assemblies, and earthing jumpers built to withstand intense electrical loads, thermal stress, and continuous track vibration.
Our manufacturing facility integrates precision power press stamping, automated CNC copper bending, silver/tin electroplating, and vacuum insulation molding. Operating under stringent quality standards, every component undergoes micro-ohm electrical conductivity testing, plating thickness measurement, and structural fatigue checks to ensure zero-defect performance on locomotive and metro fleets.
