Bimetallic screws, also called bialloy screws, are accessories used in injection molding machines. They are ordinary screws with an alloy plated onto their surface. The alloy's main function is to enhance the bimetallic screw's corrosion resistance and wear resistance. Besides injection molding machines, bimetallic screws can also be used in injection molding machinery, bakelite machinery, extrusion machinery, blow molding machinery, blown film machinery, granulation machinery, extrusion machinery, pipe machinery, sheet machinery, wire and cable machinery, and other mechanical equipment.
The materials used for bimetallic screws are primarily high-quality alloy steel, chromium-molybdenum alloy steel, and nickel-based alloys. According to customer requirements, after cutting and shaping, a special alloy material is melted and then evenly sprayed onto the screw using a special method. The screw and alloy material fit perfectly and seamlessly, achieving special properties such as water resistance, wear resistance, and corrosion resistance.
Bimetallic screws are suitable for various types of plastics with added glass fiber, plastics, and special engineering plastics such as PPA, PO, PPS, LCP, ABS fire retardant, bakelite powder, magnetic powder, and PC. A good screw is essential for the proper operation of machinery, ensuring better product quality and a longer service life. Bimetallic screws, using special processing techniques, improve their corrosion resistance, wear resistance, and mechanical properties while reducing energy consumption, making them a more practical type of screw currently available.
