When processing high filling plastics such as glass fiber and calcium carbonate with an extruder, the wear rate of the threaded section is fast, and the screw diameter needs to be scrapped every 0.2mm of wear, with an average replacement every 3-4 months, seriously affecting production continuity. Daokedao laser cladding uses nickel based tungsten carbide composite powder (WC content 30%) to achieve full coverage of the threaded section with a laser power of 2.5KW. The coating hardness reaches HV1200, the wear resistance is 8 times that of 45 # steel, and the bonding strength between the coating and the substrate reaches 480MPa, with no risk of detachment. A certain pipe production enterprise processed 30% glass fiber reinforced PP material by melting the 65mm extruder screw. After continuous production for 5000 hours, the screw thread wear was only 0.05mm, which still meets the extrusion accuracy requirements. After application, the screw replacement cycle has been extended to 18-24 months, saving 360000 yuan in screw procurement costs annually, and increasing the effective operating rate of the production line from 85% to 98%.
