Ship & boat forging: Crank shaft, shaft forging, diesel engine crankshaft, axis, bend shaft, marine shaft

Quick Detail:
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

Description:
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

Applications:

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.
