A crankshaft is a key automotive engine component that converts the linear motion of the piston into rotary motion. In other words, the force created by the pistons moving up and down is converted to a force that enables the wheels in circular motion to move forward. As one of the essential part of any engine, a crankshaft is used in the production of an automotive engine that can either be forged or cast. Crankshaft manufacturers have to, therefore, ensure that the manufacturing material used for the making of these crankshafts is of very high-quality ductile iron as they are the main rotating component of an engine. As one of the established players in the field of manufacturing of engine components, Cooper Corp is among the renowned crankshaft suppliers and crankshaft manufacturers in India as well as globally. The company is known for its manufacturing excellence coupled with great talent and dedicated workforce for over five decades now. With this in the background, let us now look into the on what it takes for the making of high-quality crankshafts.
About crankshafts in a nutshell:
Forged crankshafts have long been used for engines and are stronger than cast crankshafts which are now used extensively by automotive industries and other manufacturing units. Crankshafts are manufactured by forging and making of spheroid-shaped cast iron through the critical production process. The process includes a wide range of refined high strength steel that defines tolerance and tenacity of the engine in total. Cooper corp ensures that the steel specifications vary depending on industry use, size and applicability. The designing process takes into consideration that the crankshafts achieve extreme levels of strength and impact resistance to take care of the high-performance engines. Speaking about engines and engine components in entirety, the structure, and architecture of the crankshaft is a very complex geometry of sorts. It consists of the crank pins which connects the rods, the shaft parts that revolve in the bearings, crank arms or webs that connect crankpins to the shaft components. The crankshaft ‘main’ makes circular rotations with the help of the supporting bearings causing the offset rod journals to rotate and the big ends of the rods contain bearings which ride on the rod journals. Crankshaft manufacturers have to consider the structure and for the large number of load cycles that the crankshaft operates on; the design, production, and manufacturing processes are equally crucial. Being the hub of manufacturing, crankshaft manufacturers in India have to ensure that each step of the manufacturing process is standardized and as per international standards.
Manufacturing of crankshafts-from design to supply:
Crankshaft manufacturers in India ensure that the designing of crankshaft takes into account the engine requirements that can vary between single and multiple cylinders. At Cooper corp, all the crankshafts are conditioned to the optimal quality where all the internal stress is removed and the structure is stabilized to specified hardness. The crankshafts are induction hardened to main and pin diameter at 50~60 HRC and is equipped with the casting and support facilities for manufacturing S.G. Iron crankshafts. The cost-effectiveness, engine performance, and the strain analysis are well taken into consideration during the initial processes itself. In order to address the engine failure issues due to fatigue, crankshaft manufacturers have to make sure that accurate levels of stresses are applied and strain analysis is conducted on the basis of the nature of the load applied on the crankshaft. As one among the key players as crankshaft manufacturers in India, Cooper corp ensures that due care and caution is taken in the entire manufacturing process right from the ‘shaping on the lathe’ till the final inspection process. In its attempt to do so, each of the crankshafts manufactured by Cooper Corp is subjected to stresses that are potentially equivalent of several tonnes of force to test for its tenacity.
Cooper Corp has been a dominant player in the industry both as one of the key crankshaft manufacturers in India and as a crankshaft supplier nationally and worldwide. The products have wide industrial application including the manufacture of engines, generators, vehicular components, and automotive industry. The company has a wide network of the distribution chain and caters to individual industry requirements and industry specifications. Being one of the major crankshaft suppliers in India and globally, Cooper Corp produces ready-to-install crankshafts for high-performance automotive engines. The company has a supply chain across India and internationally with the broad network of client base having automotive, marine and industrial applications.
