Quality control and inspection of metal stamping parts is an important part of ensuring product quality. In the process of making metal stamping parts by metal stamping process, it is necessary to strictly control the properties of the products, such as strength, stiffness, corrosion resistance, high temperature resistance, etc., in order to meet the needs of different application fields. For example, the materials of metal cold stamping parts used in oil presses should meet the requirements of drawings and comply with the requirements of relevant documents.

In the quality control of metal stamping parts, factors such as material selection, tolerance and post-processing need to be considered. In material selection, the materials should be selected in accordance with the standard and strict quality control should be carried out on the materials to ensure that the quality and performance of the materials meet the requirements. In terms of tolerance control, a reasonable tolerance range should be formulated according to the requirements of the product, and the tolerance in the production process should be strictly controlled to ensure that the size and shape of the product meet the requirements. In post-processing, necessary surface treatment and heat treatment should be carried out to improve the properties of the products such as corrosion resistance, high temperature resistance and strength.

In the testing technology of metal stamping parts, a variety of testing methods can be used, such as appearance testing, size testing, mechanical properties testing, chemical composition testing and so on. Appearance testing is mainly to test the appearance quality of the product, including surface quality, grounding mark, burr quality, weld joint quality and allowable appearance defects. Dimension testing is mainly to test the dimensions of the product, including structural design, stamping part dimensions, welding dimensions and assembly quality. Mechanical performance testing is mainly to test the strength, stiffness, corrosion resistance, high temperature resistance and other properties of the product. Chemical composition testing is mainly to test the chemical composition of the product to ensure that the quality and performance of the product meets the requirements.

In short, the quality control and testing of metal stamping parts is an important part of ensuring product quality. In the production process, it is necessary to strictly control the various properties of the product and use a variety of testing methods to ensure that the quality and performance of the product meet the requirements.
