Talking about the beauty of extrusion technology

  There are many kinds of processable polymers in Dalian extrusion molding, and the products are more diverse. There are many differences in molding process, but the basic process is roughly the same. The more common process is the solid state feeding extrusion products. This extrusion process is: granular or powdered solid materials are added to the hopper of the extruder, the extruder barrel outside a heater, through heat conduction will be generated by the heater to the material in the barrel, temperature rise to the melting temperature.


  The machine runs, the screw in the barrel rotates, conveys the material forward, the material rubs and shears with the barrel, the screw and the material and the material in the movement process, produces a large amount of heat, and the heat conduction interaction causes the Gaco material to melt unceasingly, the melted material is continuously and steadily conveyed to have the certain shape. The shape of a die (or die). After passing through the die, the material in the flowing state takes the shape similar to the mouth shape, and then enters the cooling and setting device, so that the material solidifies on one side and keeps the fixed shape on the other. Under the action of the traction device, the product moves continuously, and the size of the product is obtained. Cut products by cutting, so that they can be stored and transported.


  Other extrusion products, with material characteristics, product size and output requirements, the structure, type and specifications of the extruder can be different; die structure, shape, size according to the specific product design and manufacturing; cooling and molding methods depend on the product variety and material performance; the rest of the auxiliary machine will also have many different points. However, the process links in the above block diagram are basically the same.
