The shape of each part of the automobile is unique, which is almost the same in the processing of automobile parts in Dalian. Many people find it strange: what kind of technical method can turn metal and plastic into auto parts. In fact, this involves a very complex subject: automobile manufacturing technology.

These parts are part of the automobile manufacturing process, which is called the automobile parts manufacturing process. The first step from raw materials to parts is to manufacture part blanks. The common types of automotive parts include castings, forgings, stamping parts, welding parts and powder metallurgy parts. Therefore, the processing technology of auto parts includes casting, forging, stamping, welding, powder metallurgy, plastic molding and so on.

The connecting rod is one of the main force transmission components in the automobile engine. Its small end is connected with the piston through the piston pin, and its large end is connected with the crankshaft connecting rod journal. The compressed oil-gas mixture in the cylinder combustion chamber expands rapidly after ignition and combustion, and is pressed to the top surface of the piston with great pressure. The connecting rod transmits the force on the piston to the crankshaft and drives the crankshaft to rotate.

Connecting rod components are composed of connecting rod body, connecting rod cap, bolts, nuts, etc. During the working process of the engine, the connecting rod shall bear the alternating pressure of expansion gas and inertial force. In addition to sufficient strength and stiffness, the connecting rod shall also minimize its own weight to reduce the inertial force. The cross section of the connecting rod body is I-shaped, and the size gradually decreases from big end to small end.
