Problems solved by technology

[0002] Most of the traditional pipe extrusion molding devices use a screw conveyor to make the material have a certain pressure, so that the material is extruded from the forming outlet of the mold. Recently, the market's performance requirements for metal pipes have increased, and thin-walled, high-strength The demand for pipes has increased significantly, but the extrusion pressure of the traditional screw conveyor is limited by the strength of the screw, which is no longer suitable for processing thin-walled, high-strength metal pipes; and the traditional screw conveyor is expensive and requires maintenance. high cost
