In the field of plastic processing, the problem of screw wear in injection molding machines has always plagued the industry. When expanding, we will deeply analyze the principle of screw damage, provide a detailed introduction to the process advantages of the Daokedao laser cladding equipment, introduce actual case data, and highlight the significant benefits brought by the equipment.
As the core component of plastic molding processing, injection molding machine screws face harsh working environment challenges when processing polymer materials such as PE (polyethylene) and PVC (polyvinyl chloride). These materials are in a high viscosity fluid state under high temperature and high pressure. During the rotation and transportation of the screw, the surface of the screw edge continues to withstand strong erosion from the material. At the same time, the hydrogen chloride gas released by PVC and other materials during processing can cause chemical corrosion to the metal screw. Under the dual action, the surface of the screw is prone to wear and corrosion pits, resulting in uneven plasticization of the material, directly causing a decrease of plasticization efficiency by more than 30%, seriously affecting production continuity and product quality.
Daokedao's automated laser cladding equipment targets the pain points in this industry by using high-energy density laser beams to accurately fuse high-performance wear-resistant and corrosion-resistant materials such as tungsten carbide and nickel based alloys onto the surface of screw edges. By optimizing process parameters such as laser power and scanning speed, a dense coating is formed that is metallurgically bonded to the substrate. After testing, its hardness reaches HRC58-62, demonstrating excellent wear resistance and corrosion resistance. The special coating structure makes it difficult for the material to adhere, and only a simple wipe is needed to restore a smooth surface during cleaning, greatly reducing the frequency of equipment maintenance.
A large plastic processing plant with an annual output value of over 10000 tons entrusted its 10 injection molding machine screws to the Daokedao team for laser cladding treatment. Before the renovation, the average service life of the screw was only 8000 molds, and the problems of raw material mixing and plasticization caused by surface wear were frequent, with a raw material waste rate of up to 12%. After melting treatment, the service life of the screw is increased to 22000 mold cycles, and the production stability is significantly enhanced; At the same time, thanks to the non stick properties of the coating, the raw material waste rate has been reduced to 7%, and the annual cost savings of raw materials alone exceed 800000 yuan. The comprehensive operation and maintenance costs of equipment have been reduced by more than 40%, creating considerable economic benefits for the enterprise.
