Cold stamping

During the stamping process, the material surface is not damaged, so it has good surface quality, smooth and beautiful appearance, which provides convenient conditions for surface painting, electroplating, phosphate, powder spraying and other surface treatment. Advantage Of Metal Stamping (1) The stamping parts have high precision sizes and are consistent with the die size. General assembly and use requirements can be met without further machining. (2) Generally, cold stamping parts are no longer machining, or only need a small amount of machining. (3) During the stamping process, the material surface is not damaged, so it has good surface quality, smooth and beautiful appearance, which provides convenient conditions for surface painting, electroplating, phosphate, powder spraying and other surface treatment. (4) The stamping parts are manufactured by stamping on the premise of low material consumption. The parts are light in weight and have good rigidity. After plastic deformation, the internal structure of the metal is improved, so that the strength of the stamping parts is improved. (5) Compared with castings and forgings, stamping parts are thin, uniform, light and strong. Stamping can produce workpieces with stiffeners, ribs, undulations or flanging that are difficult to manufacture by other methods, so as to improve their rigidity. Quality Control In Yonglihao, every staff emphasizes quality is first. Testing report and samples of all products will be kept by our quality control department. All materials must be provided with suppliers' certificates, and have to pass the receiving inspection before starting production. Occasionally,
