1. Cleaning and residue treatment (1) Thorough cleaning after shutdown After each shutdown, the residual materials in the screw, barrel and die head must be removed immediately to avoid carbonization or degradation of the material and corrosion of the screw surface. Use a special cleaning agent or m... read more
1. Differences in structural design and working principle (1) Number of screws and meshing method A twin-screw extruder consists of two intermeshing screws, which achieve forced conveying and shearing of materials through coordinated rotation; a single screw only relies on the rotational friction of... read more
Compared with single screw, conical twin screws and cylinders are more efficient, mainly due to their unique design and working principle. The specific advantages are reflected in the following aspects: 1. Forced conveying mechanism to reduce material backflow Single screw: Material conveying mainly... read more
1. Optimization of geometric structure design (1) Tapered channel and dynamic gap The diameter of the conical twin screw gradually decreases from the inlet to the outlet, forming a tapered channel. This design makes the material continuously subjected to the dual effects of compression and shear for... read more
The material composition of the bimetallic screw has a significant impact on its performance in the extrusion process, mainly reflected in the following aspects: 1. Wear resistance and life: The use of high-hardness, wear-resistant alloy steel can effectively extend the service life of the screw. Th... read more
