3 . The advantages of using the D2 material to make extruder screw elements
a . Wear resistance: D2 material is a high carbon high chromium tool steel with excellent wear resistance. During extruder operation, threaded elements frequently contact and rub against plastic material, so good wear resistance is required to prolong service life. The high hardness and wear resistance of the D2 grade make it an excellent choice.
b . Corrosion resistance: D2 material also has good corrosion resistance, which can resist chemical corrosion caused by contact with plastic materials. This is very important for the long-term stability and reliability of the extruder screw elements.
c . High strength: D2 material has high strength and toughness, and can withstand the stress under high pressure and high temperature conditions in the operation of the extruder. This helps reduce deformation and breakage of threaded elements and improves production efficiency and product quality.
d . Processing performance: D2 material is easy to process and manufacture, and the required hardness and performance can be obtained through heat treatment. This makes it possible to manufacture custom-made extruder thread elements with complex thread structures.
4 . Screw elements made of D2 material are widely used in the following industries
a . Plastic extrusion industry: D2 screw elements are often used in plastic extruders to extrude various thermoplastics, such as polyethylene, polypropylene, polyvinyl chloride, etc. These threaded elements are used to melt and extrude plastics, and are widely used in the production of plastic products, such as pipes, plates, profiles, etc.
b . Rubber extrusion industry: D2 screw elements are also used in rubber extruders to extrude rubber products, such as seals, pipes, rubber bands, etc. During the rubber extrusion process, the screw element plays the role of heating and plasticizing the rubber for extrusion.
c . Papermaking and textile industry: D2 screw elements are widely used in papermaking and textile equipment. In the papermaking process, threaded elements are used to extrude the pulp, forming the fibrous structure of the paper. In the textile industry, threaded elements are used to extrude fibrous materials such as yarns, filaments, etc.
d . Food processing industry: In food processing equipment, D2 screw elements are often used to extrude food materials such as dough, candy, and chocolate. These threaded elements help heat, plasticize and extrude food materials for use in food production and processing.
