Injection screw heads play a vital role in the injection molding process. They include rubber head, rubber ring and meson, these parts together to complete the sealing, mixing and plasticizing functions, has a direct impact on the quality of plastic products .
Specifically, the importance of injection screw heads is reflected in the following aspects:
Influence product quality : screw head group in the whole screw group plays the role of sealant mixing plasticization, many plastic products quality problems and screw head three small parts have a close relationship. If the details of these parts are not handled well, it will lead to a substantial increase in the scrap rate of plastic products, and even require downtime .
affects production efficiency : The role of the rubber ring is to stop the reverse, to avoid the leakage of plastic melt during injection. The speed of the check action of the rubber ring and the rubber meson directly affects the weight accuracy and production efficiency of the injection molded product. The combination of good glue head, rubber ring and glue meson can complete high-precision injection volume control, especially in the molding of transparent products and fine products, the role of these three is particularly obvious .
impact on equipment maintenance : improper handling of the details of the three small parts of the screw head will not only lead to product quality problems, but also increase the maintenance cost and downtime of the equipment. For example, the dead Angle of the right Angle is easy to crack and accumulate materials, resulting in poor flow of raw materials, and easy to produce black spots and yellowing after a long time .
To sum up, injection screw heads are indispensable parts in the injection molding process, and their quality and treatment directly affect product quality, production efficiency and equipment maintenance costs. Therefore, the maintenance and maintenance of the three small parts of the screw head is very important.
