Explanation

Also known as pressure processing. The process of making materials reach the required shape and properties through plastic deformation. Compared with mechanical cutting, plastic forming has the following characteristics: no cutting, high utilization rate of materials; When the desired shape is obtained, the structure and properties of the materials can also be improved; Suitable for large-scale production with high production efficiency; Need specialized equipment, tools, and molds. The actual use of plastic forming must consider three factors: the plastic plus property of materials, that is, the allowable plastic deformation degree of materials, which depends on the nature of materials itself (crystal type, grain size, second phase size and distribution, etc.) and deformation conditions (such as temperature, deformation rate, stress state, etc.); deformation equipment and necessary tools; Technical economy. The plastic forming methods of technology mainly include rolling, forging and pressing, extrusion, stamping, sheet metal processing, etc.
