Crankshafts

The crankshafts are mainly manufactured from forging and spheroidised cast iron and machined with very critical machining process. Crankshafts are designed based on the engine requirement, those are from single cylinder to multiple cylinders. The pin diameter, main diameter, throw, pin & main width, surface finishes are the critical parameters of crankshaft. All crankshafts are induction hardened to main & pin diameter at 50~60 HRC. We supply crankshafts both in India and to an international client base for Automotive, Marine and Industrial applications. The Cooper Corporation is equipped with casting and facilities to manufacture S.G. Iron Crankshafts. We use a CNC Sander and Super-finishing Machine in our production process and expect to install an Induction Hardening Machine.
