Summary：

The alloy screw is the core of the injection molding machine/extruder. The plastic material is transformed from a glass state to a viscous flow state in an injection molding machine, and then extruded through an alloy screw die. Made into a variety of products. So how do we measure the quality of an alloy screw? The following screw manufacturers will analyze it for everyone.

First, the output, the output refers to the production or extrusion of a given head under the premise of ensuring the quality of plasticizing.

Second, chemical, mechanical, or batch numbers are different, reducing energy consumption and reducing the burden on the main and auxiliary cooling systems. Polyethylene and polypropylene, which are both polyolefins, are also different.

Third, the difficulty of manufacturing, a good alloy screw must also be easy to manufacture and low cost.

Fourth, adaptability, the adaptability of the alloy screw refers to the adaptability of the alloy screw to the processing of different plastics, matching different heads and different products. The former is amorphous plastic. Even the same polyethylene. Therefore, different alloy screw designs are required to adapt to different materials without obvious melting point and electrical properties.

Fifth, the feeding section, the depth of the screw groove is fixed, and its function is responsible for preheating and plastic solid conveying and pushing. It must be ensured that the plastic begins to melt at the end of the feed section.

Sixth, unit consumption, unit consumption refers to the energy consumed per kilogram of plastic (rubber). The matching of the resistance of the head and the performance of the alloy screw is more important, and the quality of the finished product is not good. It is also different.
