[0002] Stamping for parts production is a common metal processing process, which is usually used to produce various metal parts, such as automotive parts, electronic equipment housings, furniture accessories, etc. Stamping is the process of processing metal sheets or wires into parts of the desired shape through dies and stamping machinery. Stamping usually requires high dimensional accuracy of parts, especially for parts that need to cooperate with other parts, accurate positioning is essential. If the positioning is inaccurate, it may lead to dimensional deviation or assembly difficulties, affecting product quality. Accurate positioning plays a vital role in the stamping process, which can ensure the dimensional accuracy, shape accuracy and production efficiency of parts. Therefore, manufacturers usually take various measures, such as using precision positioning systems, optimizing mold design and adjusting stamping parameters, to achieve accurate positioning and obtain high-quality stamping parts.
