Extrusion is mainly used for forming metal, and can also be used for forming nonmetal such as plastic, rubber, graphite and clay blanks. The French person of the 17 th century uses a manual screw press to extrude a lead pipe which is used as a water pipe and starts cold extrusion. The cold extrusion of zinc, copper and copper alloys was achieved at the end of the 19 th century, expanding to the extrusion of aluminum and aluminum alloys in the early 20 th century. The German people in the 30 s invented phosphorized and saponified surface antifriction lubricating treatment technology to make cold extrusion of steel successful, and originally used for extruding steel cartridge case. After the second world war, cold extrusion of steel has been generalized to other countries and expanded the range of applications. In the 50 s, molten glass lubrication was used, hot extrusion of steel was used and developed in the metallurgical and mechanical industries, and post-extrusion de-molding required manual pulling by hand, which was laborious, difficult, and somewhat obstructive in some corners and also prone to damage.
