Connecting rod connects the piston and the crankshaft, and transmits the force exerted by the piston to the crankshaft, transforming the reciprocating motion of the piston into the rotational motion of the crankshaft. It is one of the main transmission components of automotive engines, which transmits the pressure of the expanding gas of the piston to the crankshaft, transforming the reciprocating linear motion of the piston into the rotational motion of the crankshaft, in order to output power.

Die forging produces parts that have excellent mechanical properties, such as high strength and toughness. The process creates a tightly packed grain structure that enhances the strength and durability of the material. As a result, automotive components produced using die forging are highly resistant to wear and tear, as well as to fatigue failure.

Forged crankshafts are usually made of high-strength alloy steel, and their surfaces are usually processed by heat treatment, hardening treatment, and other processing methods to improve their wear resistance. This wear resistance can effectively reduce crankshaft wear during prolonged high-speed rotation, while also enabling the vehicle to better adapt to various working environments.

Detail Information
Advantages of Forged crankshaft

1、 High strength

Forged crankshaft is a high-strength component that needs to withstand the high pressure and high speed generated by vehicle engines. This high strength is due to the fact that the forged crankshaft undergoes multiple heat treatments and thermal deformation processes during the manufacturing process, resulting in refined grain size, improved mechanical properties, and better durability.

2、 Fatigue resistance

Forged crankshaft has certain elasticity and crack resistance, and is not easily broken during long-term high-speed rotation. Therefore, forged crankshafts have excellent wear resistance and durability in high frequency and high speed working environments.

3、 Wear resistance

Forged crankshafts are usually made of high-strength alloy steel, and their surfaces are usually processed by heat treatment, hardening treatment, and other processing methods to improve their wear resistance. This wear resistance can effectively reduce crankshaft wear during prolonged high-speed rotation, while also enabling the vehicle to better adapt to various working environments.
