Factors affecting the service life of Screw and Barrel for Horizontal Injection Molding Machine

The manufacturer of Screw and Barrel for Horizontal Injection Molding Machine tells you that the barrel screw is an important part of the injection molding machine. It is often used in the injection molding industry, but it will inevitably cause wear during use. Wear makes the gap too large and cannot be normal. Squeezing, injection and scrapping further shortens its service life. Today, the manufacturer of Screw and Barrel for Horizontal Injection Molding Machine will briefly introduce several factors that affect its service life.

1. Operating conditions
The manufacturer of Screw and Barrel for Horizontal Injection Molding Machine tells you that it will shorten its service life when it is operated in a relatively harsh environment. For example, if the temperature reaches 200℃ or higher, the barrel and screw must withstand high temperature and high pressure, especially Withstand the abrasion effect of the molten material, the load starting during pre-molding, and the huge torque and pressure, naturally these will cause wear and shorten its service life.
2. Failure mechanism
The manufacturer of Screw and Barrel for Horizontal Injection Molding Machine tells you that the main reason for the failure of most barrel screws is abrasive wear. When plastics and fillers are plasticized under high temperature conditions, they often disassemble corrosive media. These corrosive The medium will corrode the appearance of the barrel and screw. After corrosion, it is easy to be carried out by the plastic, causing material loss. Whether it is corrosion or abrasion, it will accelerate its failure time.
3. Factors of production
The manufacturer of Screw and Barrel for Horizontal Injection Molding Machine tells you that when the barrel and screw are manufactured, the material selected and the surface gold-plated material will affect their service life. At the same time, when it is running, both the speed and the back pressure will affect its service life.
How to extend the service life of the barrel and screw of the injection molding machine? When the customer is choosing, the manufacturer of Screw and Barrel for Horizontal Injection Molding Machine tells you that the compression ratio, aspect ratio, and edge width should be determined first according to the nature of the plastic being processed. Wait for the parameters to ensure that the parameters meet the actual application requirements. Secondly, you should pay attention to regular maintenance during use.
