Stamping product

Compared with castings and forgings, stamped parts have the characteristics of being thin, uniform, light, and strong. Stamping can produce workpieces with reinforcing ribs, ribs, undulations, or flanges that are difficult to manufacture by other methods to improve their rigidity. Due to the use of precision molds, the workpiece accuracy can reach the micrometer level, with high repeatability and consistent specifications, and can be punched out with holes, protrusions, etc.

Product Description

Stamped parts are formed and processed by applying external forces on plates, strips, pipes, and profiles using a press and mold, resulting in plastic deformation or separation to obtain the desired shape and size of the workpiece (stamping part). Stamping and forging belong to plastic processing (also known as pressure processing), collectively known as forging. The stamping blanks are mainly hot-rolled and cold-rolled steel plates and strips.

Cold stamped parts generally do not undergo cutting or require only a small amount of cutting. The precision and surface state of hot stamping parts are lower than those of cold stamping parts, but they are still better than castings and forgings, and the cutting amount is less.
Stamping is an efficient production method that uses composite molds, especially multi-station progressive molds, to complete multiple stamping processes on a single press, achieving fully automatic production from strip uncoiling, leveling, punching to forming and finishing. High production efficiency, good labor conditions, low production costs, typically producing hundreds of pieces per minute.
Stamping is mainly classified by process and can be divided into two categories: separation process and forming process. The separation process, also known as punching, aims to separate the stamped part from the sheet metal along a certain contour line while ensuring the quality requirements of the separated section. The surface and internal performance of stamping materials have a significant impact on the quality of stamping products, requiring accurate and uniform thickness of stamping materials; The surface is smooth and clean, without spots, scars, scratches, surface cracks, etc; Uniform yield strength without obvious directionality; High uniform elongation; Low yield strength ratio; Low work hardening.
