Crankshaft is the core component of engine, its manufacturing process is complex, requiring high precision and high strength.
1. Material selection
Commonly used materials: forged steel, ductile iron, alloy steel, etc.
Material requirements: high strength, wear resistance, fatigue resistance.
2. Forging or casting
Forging process:
Heat billets to forging temperature (approx. 1200°C).
Use the forging press to form the crankshaft shape initially.
Advantages: dense tissue, high strength.
Casting process:
Suitable for nodular cast iron crankshaft.
Molded by mold pouring.
Advantages: Low cost, suitable for complex shapes.
