Fe-Base Alloy Screw and Barrel manufacturers take you to understand the characteristics of double alloy screws

The manufacturer of Fe-Base Alloy Screw and Barrel tells you that the physical properties of different materials of the double alloy screw are very different. Therefore, the processing functions are also different, and there are different requirements for the structure and geometric parameters of the single-screw extruder. The manufacturer of Fe-Base Alloy Screw and Barrel tells you that the rubber extruder screw is very different from the plastic extruder screw: such as screw aspect ratio, screw groove depth, screw structure (the plastic extruder screw has mixing elements, shear cut components), etc.

The double alloy screw is different from the rubber extruder screw: Fe-Base Alloy Screw and Barrel manufacturer tells you that the cold feed extruder screw is different from the hot feed extruder screw.
The Fe-Base Alloy Screw and Barrel manufacturer tells you that the twin alloy screw plastic extruder screws are also different. For example, there is a big difference between polyvinyl chloride and polyolefin. The former is an amorphous plastic with high viscosity, sensitive to temperature, and no obvious melting point. The manufacturer of Fe-Base Alloy Screw and Barrel tells you that the latter is a crystalline plastic with a low viscosity and a significant melting point. Even polyethylene and polypropylene, which are both polyolefins, are different. Even the same polyethylene, but due to different manufacturers, or different batch numbers, its performance is also different. The manufacturer of Fe-Base Alloy Screw and Barrel tells you that the same kind of plastic has different processing functions for powder and granular. Preheating and non-preheating also affect the processing function. Therefore, different screw designs should be adopted to adapt to different materials.
