The importance of screw barrel to plastic machinery

Por Cathy Lin September 25th, 2024 vistas 6
‌ The importance of screw barrel to plastic machinery is mainly reflected in the process of conveying, compacting, melting, stirring and pressuring plastics. ‌

The screw barrel is an important part of the injection molding machine, and its function is to realize the transportation, compaction, melting, mixing and pressure of the plastic in the barrel through the rotation of the screw. This process is completed through the rotation of the screw in the barrel, wherein the plastic and the inner wall of the barrel, the bottom surface of the screw groove, the thrust surface of the screw edge and the friction between the plastic and the plastic produce friction and mutual movement, this combination of motion causes the plastic to push forward, and the heat generated by the friction is absorbed to increase the temperature of the plastic and melt the plastic. This process is essential for the proper operation and efficient production of plastic machinery ‌.

In addition, the design and performance of the screw barrel have a great impact on the production efficiency of the injection molding machine. A screw barrel with good design and performance can reduce machine failures and downtime and improve production efficiency. At the same time, its heat transfer performance can help maintain a stable screw temperature and reduce energy consumption ‌.

In summary, screw barrel is not only the core parts of plastic machinery, its performance and design directly affect the quality of plastic products, production efficiency and energy consumption, so it occupies an extremely important position in plastic machinery.
