What are the requirements for the production of PC material for the barrel and screw? Why do you require 270-300° PC material to be produced with our machine only 210-250° can be produced, what is its melting point? A: Production of PC materials
What are the requirements for barrel and screw for producing PC materials? Why is it required that PC materials with a temperature of 270-300° can be produced with our machines at only a temperature of 210-250°? What is its melting point? Answer: To produce PC materials, the screw and barrel materials are required to be hard, wear-resistant, and corrosion-resistant. Generally, alloy materials, stainless steel, etc. are used. The compression ratio of the screw should be greater than 1:20, usually 1:18;
It is mainly caused by the temperature deviation of the machine. Plastic is an amorphous inorganic material. It has no melting point, only softening temperature, which varies according to the characteristics of the material. That is, the grade of the material is different, and the temperature is also different. The standard is 270-300°; injection molding When processing different plastic products, the machine screw barrel needs to set specific parameters according to the specific characteristics of different plastic raw materials.
