Shanghai Songjiang hardware stamping parts exporter, stamping process classification + stamping accuracy up to 0.01mm

The employees of Shanghai Songjiang Hardware Stamping Parts Exporter once introduced that stamping is mainly classified by process, which can be divided into two categories: separation process and forming process. The following Xiaoshuo will take you to understand: The separation process is also called blanking, its purpose is to separate the stamping parts from the sheet along a certain contour line, while ensuring the quality requirements of the separated section. The purpose of the forming process is to make the sheet metal plastically deform without breaking the billet to make a workpiece of the required shape and size. In actual production, multiple processes are often applied to one workpiece. Blanking, bending, shearing, stretching, bulging, spinning, and correction are the main stamping processes. Separation process (punching): refers to a basic stamping process that uses molds to separate materials. It can be directly made into flat parts or prepare blanks for other stamping processes such as bending, deep drawing, and forming. It can also be used in formed stamping Cut, trim, etc. on the piece. The blanking process accounts for about 50% to 60% of the entire stamping process. Bending: A plastic forming method of bending metal sheets, pipe fittings and profiles into a certain angle, curvature and shape. Deep drawing: Deep drawing is also called drawing or calendering. It is a stamping method that uses a die to make a flat blank after punching into an open hollow part. Stretching: Tensile force is applied to the sheet by the stretch die, which causes uneven tensile stress and tensile strain on the sheet, and then the mating surface of the sheet and the stretch die gradually expands until it is fully fitted with the stretch model surface, etc. . Hardware, 15 years of ingenuity focused on metal stamping parts processing, 20000+ sets of stamping die customization production experience, monthly 100+ sets of mold processing capacity, daily production capacity of 3 million punching times, stamping accuracy up to 0.01mm, 16 quality inspection layers are strict check. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve production quality problems. Choose, choose rest assured!
