China Custom Stamping

Description of China Custom Stamping

Cars are known as "machines that change the world". Due to its strong industrial correlation, the automotive industry is considered an important indicator of a country's economic development level. There are four major processes for automobiles, and Stamping technology is the top priority and also the top of the four processes.

1. Stamping concept

Stamping is a forming and processing method that relies on a press and mold to apply external forces to plates, strips, pipes, and profiles, causing plastic deformation or separation, in order to obtain the required shape and size of workpieces (stamped parts). Stamping and forging belong to plastic processing (also known as pressure processing), collectively known as forging. The stamping blanks are mainly hot-rolled and cold-rolled steel plates and strips. 60% to 70% of the world's steel is made of sheet metal, most of which is stamped into finished products.

The body, chassis, fuel tank, radiator, boiler drum, container shell, iron core silicon steel sheets of motors and electrical appliances of automobiles are all stamped and processed. There are also a large number of stamping parts in products such as instruments, household appliances, bicycles, office machinery, and household utensils.

2. Characteristics of stamping process

A. Stamping is a processing method with high production efficiency and low material consumption. The stamping process is suitable for the production of large batches of parts and products, facilitating mechanization and automation, with high production efficiency. At the same time, stamping production not only strives to achieve less waste and no waste production, but also can be fully utilized even if there are leftover materials in certain situations.

B. The operation process is convenient and does not require the operator to have a high level of skill.

C. Stamped parts generally do not require further mechanical processing and have high dimensional accuracy.

D. Stamped parts have good interchangeability. The stamping process has good stability, and the same batch of stamping parts can be interchanged and used without affecting assembly and product performance.

E. Due to the use of sheet metal as the material for stamping parts, their surface quality is good, providing convenient conditions for subsequent surface treatment processes such as electroplating and painting.

F. Stamping processing can obtain parts with high strength, high stiffness, and light weight.

G. The cost of mass produced stamping parts using molds is low.

H. Stamping can produce complex shaped parts that are difficult to machine using other metal processing methods.
