                In the process of cold extrusion, the deformation resistance of extruded materials is high, and the deformation resistance of steel is more than 2000mPa. The manufacturing of high-pressure die puts forward higher requirements for die structure and technology. In recent years, with the vigorous development of material science and computer technology, new die materials emerge in endlessly. Next, I will take you to understand the metal surface treatment process.

                

              The surface of metal workpiece is shot peened, and the particle size is small. The whole surface is treated with micro humidification. The surface of metal workpiece after micro humidification is rusted to form a layer of evenly distributed fluffy rust layer. After rust treatment, the surface of metal workpiece is coated with lubricant to finish metal surface treatment.


              Shot blasting is to use the high-speed rotating impeller in the shot blasting machine to throw the projectile onto the continuously rotating workpiece in the drum, so as to achieve the purpose of cleaning the workpiece. It is suitable for the sand removal and rust removal of various industries. The process of fine particle shot blasting is to put the metal workpiece into the shot blasting machine, and the high-speed rotating impeller in the shot blasting machine will throw the shot at the metal workpiece continuously rotating in the drum.


              In order to form lubricating film with different thickness, humidification effect and rust layer thickness should be controlled.
