Problems solved by technology

[0002] At present, the production capacity of domestic extruders is very large, but the technical content is not high, and the added value of the products is not high. The key technology of extruders lies in the screw. Now the screws at home and abroad are all single-angle (threaded) in the manufacturing process. The sheet and the screw body are set at an inclination, and the formed inclination angle), although this kind of screw is easier to process, but the efficiency of the extruder is not high, and the output is limited by the physical characteristics of the material. If you need to process the material The components are complex, containing oily components, which slip in the screw. Therefore, it is necessary to design different pushing angles, that is, the above-mentioned inclined angles, in the feeding part, in the middle of the screw and in the final pressure extrusion part. Different push angles to increase output
