Metal ball head brackets are made by applying external force to sheets, strips, tubes and profiles through punching machines and dies to plastically deform or separate them to obtain the desired shape and size. Forming and processing methods of workpieces (stamping). Plastic working (or pressure working), collectively referred to as casting. Stamping is a forming process in which a workpiece (stamping) of the required shape and size is obtained by applying an external force to the sheet, strip, pipe and profile by a stamping machine and a die to cause plastic deformation or separation. Stamping and forging are both plastic processing (or pressure processing), collectively referred to as casting. Stamping blanks are generally hot-rolled and cold-rolled steel sheets and strips. In many areas, 60-70% of the steel of ball bracket manufacturers is sheet metal, most of which are stamped into finished products. Body, chassis, fuel tank, radiator sheet, boiler drum, container shell, motor, electrical iron core silicon steel sheet, etc. are all stamping processing. There are also a large number of stampings in products such as instrumentation equipment, household appliances, bicycles, office machinery, and living containers.
