Changshu smoothly for plastic processing factory talk about plastic extruder screw requirement for material

Plastic extruder for extrusion molding tool, the production of raw materials is different, the wear degree of plastic extruder screw is not same, equipment used in the life of the screw is not the same. Now extruder screw is made of double alloy material need meet the following requirements to normal production. Changshu well below da plastic processing factory talk about plastic extruder screw requirement for material.



the first, the mechanical properties of high: should have sufficient strength, to adapt to the working conditions of high temperature and high pressure, improve the service life of the screw. Equipment at the time of operation due to the friction between material can produce high temperature so in production must be high temperature resistant materials for production.



second, mechanical processing performance is good, want to have better performance of machining and heat treatment performance. Because the rubber in equipment in the screw tubes to the second mixer and mixing, so in the production of screw need to have a better cutting ability.



the third, corrosion resistance and anti-wear performance is good, because the device in production will be running for a long time, and some material is corrosive, so the screw corrosion resistance is required.
