HOT FORGING 630T 20Cr engine rocker arm 0.4kg

Engine rocker arm: The engine rocker arm is one of the important components in the automobile engine. It connects the camshaft and the valve and plays the role of transmission, control and adjustment of the valve switch. It withstands the pressure and impact under high-speed operation and ensures the normal operation of the engine. The design and build quality of the rocker arm are critical to engine performance and reliability.

Company Profile

Nanjing Liju Precision Forging Co., Ltd. was established in 1998. It has been engaged in the development and manufacturing of automotive, forklift parts, electric power, aviation, industrial and mining, petrochemical metal and non-ferrous metal structural parts for many years. The process includes forging, casting, stamping, die-casting and other metal forming.

Forging process

Liju's Forged Components Division specializes in precision machine forging processes.

Forging is a manufacturing process in which metal is hammered, pressed, or rolled under high local pressure and shaped into high-strength parts called forgings. This metalworking method has been used for centuries and has been traditionally used to make tools, weapons, kitchen utensils and jewelry.

During the machining forging process, the coarse grain structure of the metal is broken down into finer grains, and a grain structure better aligned with the required directional strength can be obtained; in addition, pores may be removed during this process and low-density/empty spaces, and seal cracks.

As a result, forged parts are much stronger than parts produced by any other metalworking process. Therefore, forgings are widely used in applications where high strength is required, reliability and personal safety are crucial.
