The characteristics of injection screw barrel for PC products

‌ The main features of injection screw barrels for PC products include high wear resistance, corrosion resistance and proper heating control. ‌
The characteristics of injection screw barrel are mainly reflected in the following aspects:
‌ high wear resistance ‌ : In order to cope with the high viscosity and easy decomposition characteristics of PC material, injection screw barrel is usually made of high wear resistant materials, such as stainless steel quenched parts, SKD61 nitriding and quenched parts, etc., to ensure that the efficient plasticizing effect ‌ in long-term use.
Corrosion resistance ‌ : Because PC material is sensitive to water and easy to hydrolyze at high temperature, the surface treatment of injection screw barrel is very important. It is usually treated with hard chrome plating to prevent corrosion and ensure the durability of the barrel ‌.

‌ Proper heating control ‌ : In order to prevent the PC material from breaking down at high temperatures, the design of injection screw barrels requires precise temperature control. The feeding section is long, the homogenizing section is short, and the compression ratio is moderate to ensure that the plasticizing process is completed in the appropriate temperature range ‌.

Through these features, the injection screw barrel can effectively handle PC materials to ensure product quality and production efficiency.
