The main reason that affects the size and shape accuracy of precision stamping parts? 'Hardware'

The main reasons that affect the size and shape accuracy of precision stamping parts are springback and distortion. Since plastic deformation is always accompanied by elastic deformation, springback will occur after unloading, resulting in a decrease in size and shape accuracy. Dongguan Hardware will give you a detailed answer! The surface quality of precision stamping parts mainly refers to the scratches caused during the forming process. In addition to the unreasonable or uneven die gap and rough mold surface, the cause of scratches is often due to the adhesion of materials to the mold. For example, stainless steel deep drawing is prone to this problem. The volume of metal does not change during plastic deformation. Therefore, the thickness of the plate must be thinned during the elongation deformation, which will directly affect the strength of the precision stamping parts, so the precision terminals that require strength often have to limit their thinning rate.
