Compared to castings and forgings, stamped parts are thinner, more uniform, lighter, and stronger. Stamping can produce workpieces with reinforcing ribs, ridges, undulations, or flanges that are difficult to manufacture using other methods, thus improving their rigidity. Due to the use of precision dies, workpiece accuracy can reach the micrometer level, with high repeatability and consistent specifications; features such as recesses and bosses can be stamped out. Cold-stamped parts generally require no further machining or only minimal machining. Hot-stamped parts have lower accuracy and surface finish than cold-stamped parts, but are still superior to castings and forgings, requiring less machining.
Stamping is a highly efficient production method. Using compound dies, especially multi-station progressive dies, multiple stamping processes can be completed on a single press (single-station or multi-station), achieving fully automated production from uncoiling, leveling, blanking to forming and finishing. It boasts high production efficiency, good working conditions, and low production costs, typically producing hundreds of pieces per minute. Compared with other methods of machining and plastic forming, stamping has many unique advantages, both technically and economically.
