Corrosion-Resistant Screw Bushings for Rubber Particle Modification Production Suitable Spare Parts

The extruder bushing is a key accessory installed in a specific part of the extruder. It is usually located inside the barrel and fits closely with the screw. Its main function is to reduce the friction between the screw and the barrel, protect the barrel from wear, ensure that the screw rotates in a stable environment, and achieve efficient material conveying, plasticizing and extrusion processes.

Question 1: Does your company have any issues with the inner walls of machine barrels or liners that come into contact with materials being not wear-resistant, and the replacement frequency of threaded components being fast, which seriously affects production efficiency?

Our solution: Using our independently developed alloy material BLM60 (Ni60Tungsten Carbide), the hardness can reach HRC62-64 Mainly used for processing liner or spray welding liner inner walls, for materials and industries that require ultra-high wear resistance.Why we choose BLM60?
BLM60, the nickel based alloy materials with excellent wear resistance and corrosion resistance have significantly improved compactness; The metallographic structure is more detailed; A significant increase in hard wear-resistant phase carbides! Thus achieving twice the wear resistance of vacuum sintered alloys; The alloy layer has been changed from an 8-shaped alloy layer to a waist shaped elliptical 8-shaped alloy layer! Sharp corners provide better wear resistance and support.
(The wear resistance test shown in the following figure)
