Introduction of cold processing technology in sheet metal processing

Sheet Metal Processing manufacturers have more than ten years of production and processing experience in sheet metal processing. Sheet metal processing belongs to a kind of metal processing, but its use is not limited to metal processing. Sheet metal processing generally uses hot processing and cold processing. How to choose the two processes needs to be used according to specific requirements and regulations. Sheet metal processing uses various cutting tools and equipment to cut off the excess metal, and then uses various forming molds to cast the metal into the shape we want. Sheet metal processing requires relatively high shape and size of sheet metal parts, so drawings will be drawn in the early stage to determine the order of each processing process. Cutting methods include turning, drilling, milling, planing, grinding, broaching, etc. In the metal processing technology, cold working is the corresponding to hot working. Cold working refers to the processing technology that causes plastic deformation of metal at a temperature lower than the recrystallization temperature, such as cold rolling, cold drawing, cold forging, stamping, cold extrusion, etc. Cold working technology can increase the resistance to deformation of metals. While forming metal parts, various metal fusion can be used to improve strength and hardness. However, cold working will reduce the plasticity of metals. Generally, the metal will be made into a suitable model first and then cold working process. Cold working is suitable for processing metal parts with small cross-section size and high processing size and surface roughness requirements.
