The modern technique of cold metal stamping is carried out using expensive special dies, without preliminary heating of the workpiece and with its subsequent deformation strengthening. This information was provided to us at http://www.ku-shtamp.ru/
Cold forging is today considered the most advanced method for the manufacture of high-precision and relatively small workpieces, both based on steel and non-ferrous metals. The main advantages of using this technique include the fact that with the help of its application it is possible to reduce to a minimum the percentage of waste material used, no great labor intensity is required, the cost of cold stamping is very profitable, and the final result is a high-precision part with a minimum level of roughness.
The quality of the final result and the possibility of cold forming depend on the quality of the metal used. Pre-treatment of the material used is of great importance: removal of scale, various deformations or contamination. Depending on the parameters of the stamps used and the required deformation, modern cold stamping can be sheet or volumetric. The modern metallurgical industry today actively uses the cold stamping method, as it is a rational, efficient and cost-effective approach with a minimum percentage of waste.
The percentage of material used when cold forming is equivalent to 95 percent, which is considered an excellent indicator. Also, this technique gives an excellent fatigue strength factor when exposed to dynamic loads. But for cold stamping it is necessary to have specialized and expensive equipment; from the most rational and efficient side, cold stamping can be used in large-scale production.
