1. Ship & boat forging: Crank shaft, shaft forging, diesel engine crankshaft

2. The largest crankshaft supplier in China, the factory is a China central enterprise;

3. The crankshaft used for heavy diesel engine

The diesel engine crankshaft has following characters:

1. The metal grain is continued and same direction as metal grain flew, fatigue of component is increase more than 25%;

2. Material saving. By our manufacture , material saving is more than 30%;

3. Large batch supply. With worldwide new heating and production technology, we can save more power;

4. Low machining needed;

Material ready—–Ingot billets, slab, round bar—-Chemical analysis—-cutting—-Forging—-Heat treatment—-Inspection—-Stock of un-machined forgings—-Lathe—-test—-Marking—-Packing after machining finished

The crankshaft is used for heave diesel engine, it transmit the torque through its moving. The heavy diesel engine is used in many industries, such as ship & boat industry.

The factory has been certified by ABS, DNV, BV, GL, LR, KR, NK and CCS.
