With continuous development of manufacturing industry, metal stamping has become an indispensable part of it. Metal stamping is a manufacturing process that uses stamping molds to form metal sheets, with the advantages of high efficiency, high accuracy, and low production costs. This article will introduce in detail the process flow, equipment and application of metal stamping, quality control and detection technology analysis, as well as market trend and future development prospects.

1.Process flow, equipment, and application of metal stamping

1) Process flow

The process flow of metal stamping includes steps such as sheet cutting, forming, punching, bending, shaping, cleaning, and surface treatment. Among them, forming is the core step of stamping parts processing, and corresponding stamping molds need to be made according to the product design drawings to form and process the metal sheet.

2) Equipment and Applications

The equipment required for metal stamping includes punching machines, stamping molds, cutting machines, bending machines, shaping machines, cleaning machines, and surface treatment equipment. Metal stampings are widely used in industries such as automotive, electronics, and mechanical manufacturing, and the products are automotive body parts, electronic housings, and mechanical components etc.

2. Quality Control and Inspection Technology Analysis of Metal Stamping

1) Quality control

The quality control of metal stamping needs to be controlled from aspects such as material selection, mold design, processing technology, and equipment maintenance. Among them, the quality of materials has a crucial impact on the quality of finished products, and it is necessary to choose high-quality metal sheets. Mold design requires accurate calculation and production based on the product design drawings to ensure that the size and shape of the processed products meet the requirements. The processing technology needs to follow standardized operating procedures to ensure stable quality of the finished products. The maintenance of equipment is also an important link in ensuring processing quality.

2) Detection technology

The quality inspection of metal stamping requires inspection from multiple aspects such as appearance, size, and material. Common testing methods include appearance testing, size testing, hardness testing, physical performance testing, and chemical composition testing. Among them, appearance inspection is the most basic detection method, which can be carried out through naked eye observation, photography, microscopy, and other methods. Measurement tools such as micrometer, caliper, height gauge, etc. are required for dimension inspection. Hardness testing can be carried out by means of a hardness tester, physical property testing can be carried out by means of tensile testing, impact test, twist test, etc., and chemical composition testing can be carried out by means of spectral analysis, etc.
