The method of billet crankshaft manufacturing is mainly decided according to the crankshaft material selected by our customers. Meanwhile, different kinds of machining craft can be customized.

Cast crankshaftManufacturing of nodular cast iron crankshaft usually adopts casting because this kind of material features low cost and high cost performance. Nodular cast iron crankshaft has the following performances: wear resistant, impact resistant and stress resistant etc. It can be widely used for equipment sets requiring transmission crankshaft such as air compressor and refrigerating machine.




Forged crankshaftWhen the crankshaft selected by our customer is made of carbon steel or alloy steel, we usually adopt forging. Thus, this kind of crankshaft can have stronger resistance to impact, tensile force and resistance to stress. It can be widely used on automobile and compressor.

Superior material, precise machining equipment and rich experience should be equipped in order to produce a superior crankshaft. Nazhen has all these features.
