The dimensional accuracy of Ruishuo precision metal stamping parts is measured by tolerance registration. The national standard 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 size. The larger the allowable range of variation (tolerance value), the less difficult the machining.

The dimensional accuracy of hardware stamping parts refers to the difference between the actual size of the stamping parts and the basic size. The smaller the difference, the higher the dimensional accuracy of the hardware stamping parts. The main factors that cause the dimensional error of hardware stamping parts are: the manufacturing precision of the convex and concave molds; the gap between the convex and concave molds; the elastic recovery of the material after stamping; accidental factors in the production process, such as inaccurate positioning and unstable material performance.

The surface quality of metal stamping parts cannot be higher than the surface quality of the raw materials, otherwise it needs to be increased by subsequent processing to increase the production cost.

The dimensional accuracy of metal stamping parts can generally be divided into two types: ordinary and precision. Ordinary level is the accuracy that can be achieved by more economical means. Precision grade is the precision that can be achieved by stamping technology. The hardware company mainly engaged in precision stamping needs to control the product size at +/- 0.02mm.
