In metal technology, corresponding to hot working, cold working refers to the processing technology that can cause plastic deformation of metal below the recrystallization temperature, such as cold rolling, cold drawing, cold forging, stamping, cold extrusion, etc. Cold working has great deformation resistance. While forming metal, work hardening can be used to improve the hardness and strength of the workpiece, but it will reduce the plasticity. Cold working is suitable for processing metal auto parts with small section size and high requirements for machining size and surface roughness.

The automobile sheet metal processing industry is facing the pressure of reducing manufacturing costs year by year. In addition to seeking improvement and reform in management, technological innovation is also one of the important methods.

Due to the characteristics of the new sheet metal process, advanced sheet metal equipment software support and design, laser cutting process, bending process.

Metal plastic forming is a process that uses the plastic properties of metal materials to make them have the required shape. After forming, the structure and properties of metal materials are improved. The components subject to alternating load or bad stress conditions generally need plastic forming process to meet the use requirements. Plastic forming is a chip free forming method, which can make the workpiece obtain good streamline shape and reasonable material utilization. The plastic forming method can make the workpiece size reach high precision, and the automobile sheet metal parts have high production efficiency.

Plastic forming includes cold forming, warm forming and hot forming. The influence of temperature on material properties should be considered in warm forming, and the creep effect of materials should also be considered in hot forming. Metal plastic forming includes block forming, sheet metal forming and rolling (see Plastic Mechanics). All kinds of plastic forming are based on the premise that metal materials have plastic properties, all of which require external forces, all of which have the influence of external friction, and all follow the common rules of metallurgy and plastic mechanics.
