The manufacturing quality of stamping parts is particularly harmful to the quality of the entire vehicle, especially cars and various passenger cars. In the production of stamping parts, the test fixture (usually referred to as a test fixture) used by technical professionals is often used as a large and medium -sized stamping part with a complex indoor spatial geometric structure, car interior parts, and welders rolled. Means to control the quality of the product between the process. This detection tool has the advantages of fast, accurate, intuitive, convenient, and is particularly suitable for the needs of large -scale production. After the mid -to -late 1980s, with the rapid development of the automobile and passenger car industries, stamping detection tools have been widely used in the Chinese automobile industry.

The total weight of the car's hardware stamping parts is relatively light, the size of the product is relatively strong, the surface is clean, beautiful and generous, and the processing and customization of precision hardware do not need to do too much surface treatment. Therefore, in the process of selecting the raw materials of the car's hardware stamping parts, the following standards should be followed:

1. The raw materials selected by the car hardware stamping part must first meet the performance indicators of automobile parts.

2. The raw materials of the car hardware stamping parts should have good performance.

3. With good rationality, it can ensure the quality of the raw material, and at the same time saves product costs
