During the movement of Dalian extruded materials, they rub and shear with the barrel, screw and materials, resulting in a large amount of heat. Combined with heat conduction, Jiake's materials are continuously melted, and the molten materials are continuously and stably transported to the die (or die) with a certain shape.

After passing through the die, the flowing material takes the shape similar to the mouth shape, and then enters the cooling setting device to solidify the material while maintaining the established shape. Under the action of the traction device, the product can move forward continuously and obtain the product size. Cut off the products by cutting for storage and transportation. Extrusion molding is also called extrusion in plastic processing.

耀彩网In the processing of non rubber extruder, the pressure of hydraulic press is used to extrude the die itself. It refers to a processing method in which materials are heated and plasticized while being pushed forward by the screw through the action between the extruder barrel and the screw, and continuously pass through the machine head to make products or semi-finished products with various sections. Pressure forming is to exert strong pressure on the metal blank placed in the mold cavity.

It is a plastic method to force the metal blank to produce directional plastic deformation and extrude it from the die hole of the extrusion die, so as to obtain the required section shape, size and parts or semi-finished products with certain mechanical properties. Compared with stamping and cold heading process, extrusion process is suitable for copper aluminum and low carbon steel, which are easy to deform and have simple shape but large deformation. Extrusion molding has great flexibility. Products with different shapes, specifications and varieties can be produced on one equipment only by replacing extrusion tools such as molds. The operation of replacing extrusion molds is simple, fast, time-saving and efficient.
