Will material residues be deposited on the injection machine after it has been working for a long time?

It is indeed possible for material residues to deposit on injection machines after prolonged operation. During the injection molding process, plastic materials melt at high temperatures and are injected into the mold. Some materials may leave residues in the nozzle, screw, barrel, and even cooling system. The accumulation of these residues not only affects the operating efficiency of the injection machine, but may also lead to poor flow inside the machine, affecting the quality of injection molding. When different types of materials are alternately used multiple times in the machine, the deposition of material residues becomes more pronounced, especially under high temperature conditions, where certain plastic materials may degrade or carbonize, forming more difficult to remove deposits. If these residues are not cleaned up in a timely manner, they may increase the frictional resistance of the screw, clog the nozzle, and even affect the accuracy and surface quality of the mold. In addition, long-term accumulation of residues may also cause corrosion or damage to machine components. Therefore, it is necessary to regularly clean and maintain the injection machine to prevent residue accumulation, maintain the good working condition of the machine, and ensure production efficiency and product quality.
