Do you know the difference between casting and stamping parts in Dalian

Stamping is mainly classified by process, which can be divided into separation process and forming process. The purpose of the separation process, also known as blanking, is to separate the stamping part from the sheet along a certain contour line and ensure the quality requirements of the separation section. Stamping is an efficient production method. By using compound dies, especially multi station progressive dies, multiple stamping processes can be completed on one press to realize full-automatic production from strip uncoiling, leveling, blanking to forming and finishing. High production efficiency, good working conditions and low production cost. Generally, hundreds of pieces can be produced per minute. The purpose of the forming process is to make the sheet metal plastic deformation without breaking the blank, and make the workpiece with the required shape and size. In actual production, many processes are often applied to a workpiece. Blanking, bending, shearing, deep drawing, bulging, spinning and correction are the main stamping work.

Cast parts are metal shaped objects obtained by various casting methods, that is, molten liquid metal is injected into the prepared mold by pouring, injection, suction or other casting methods, and then cooled, sand falling, cleaning and post-treatment to obtain objects with certain shape, size and performance. The difference between metal stamping parts and castings: with the characteristics of thin, uniform, light and strong, stamping can produce workpieces with stiffeners, ribs, undulations or flanging that are difficult to be manufactured by other methods, so as to improve their rigidity. Due to the use of precision dies, the workpiece accuracy can reach micron level, and the difference between heavy stamping parts and castings is that they are thin, uniform, light and strong. Stamping can produce workpieces with stiffeners, ribs, undulations or flanging that are difficult to be manufactured by other methods, so as to improve their rigidity. Due to the use of precision die, the workpiece precision can reach micron level, with high repetition precision and consistent specifications. It can punch holes, bosses, etc. Hardness testing of stamping parts, hardness testing of metal stamping parts adopts Rockwell hardness tester.
