Varroc has proven its mettle globally in the metallic business by the impeccable design, development, manufacturing and supply of high performance and cost effective components through environment friendly practices.


Forging and Machining Business

Our metallic forging division has three manufacturing plants (in addition to the integrated plant at Pant Nagar) and an R&D center in Aurangabad, India. Our forging business supplies precision-forged and machined parts for engine and transmissions to two-wheelers, besides also manufacturing four-cylinder crankshafts for commercial vehicles and stationary engines. We also supply key products for two-wheelers, three-wheelers and four-wheelers, including crank pins, connecting rods, flanges, ring gears, crankshafts, camshafts, knuckles, front axle beams and hydraulic components to leading OEMs, tier-one suppliers in India and for export to Europe. The manufacturing capabilities of forging include hot, warm and cold forging, heat treatment, post heat treatment machining and soft machining. The division has a crankshaft facility to cater to the commercial vehicle segment. The manufacturing capabilities of the crankshaft facility include forging and testing, and the engineering capabilities include design and drafting, simulation, post processor tool path as well as product design.

Engine Valves Business

Our metallic valves division has two manufacturing plants and one R&D center in India. R&D centers are involved in the development to realisation of high performance technologies like sodium filled valves, hollow engine valves and titanium valves, and provide developmental support to customers in North America, Europe and Asia. We supply to all segments of the automotive industry and have access to major clienteles in the international market given that nearly half of the engine valves we produce are exported. Our metallic valve manufacturing capabilities include forging, heat treatment, induction hardening, pattern hardening, precision machining, hommel inspection and ultrasonic inspection.
