What is the dimensional accuracy of metal stamping parts?1

Metal stamping parts are widely used in civil and industrial applications. However, according to different industries and products, the dimensional accuracy requirements of metal stamping parts are different. For precision industries such as watches, automobiles, and medical care, metal stamping is used. The dimensional accuracy of the pieces is high. Many people don't know much about the dimensional accuracy of metal stamping parts. Introduction to the dimensional accuracy of metal stamping parts: The dimensional accuracy of metal stamping parts refers to the difference between the actual size of the stamping part and the basic size. The smaller the difference, the higher the dimensional accuracy of the metal stamping part. The dimensional accuracy of metal stamping parts is measured by tolerance registration. The national standard stipulates that it is divided into 20 levels, from IT01, IT0, IT1, IT2 to IT18. The larger the number, the lower the tolerance level (processing accuracy), and the allowable change in size The larger the range (tolerance value), the smaller the processing difficulty. The dimensional accuracy of stamping parts can generally be divided into two types: precision level and ordinary level. The precision level is the accuracy that can be achieved technically in the stamping process, while the ordinary level is the accuracy that can be achieved by more economical means. When the mold manufacturing accuracy is high, the external dimension accuracy of the metal stamping parts can reach IT10 level, and the inner hole size can reach IT9 level. The factors that affect the dimensional accuracy of metal stamping parts during the production process include: the manufacturing accuracy of the metal stamping die; the assembly process of the metal stamping die; the elastic recovery of the material after stamping; and other accidental factors during the production process, such as inaccurate positioning and material performance. Instability, etc., will affect the dimensional accuracy of metal stamping parts. Therefore, the high dimensional accuracy of stamping parts that you want to produce must be considered from these aspects.
