Plastic extruder, extrusion system host one of the most important for not only the role of transport in plastic, while the plastic extrusion, plastic, lightweight shape also plays an important role in the rational use of screw structure and parameters of the desired product quality and yield important role.
To fulfill the specifications of different plastics processing, there is very much to live, usually within pursuing categories: sort gradient (the equidistance deep), gradient-based (and other deep non-isometric), mutant , mind shape, torpedo, etc.. Screw type of Plastic extruder utilized largely to decide the actual components and producing specifications extruder. (1) non-crystalline is greater than a pretty broad temperatures softening, and is also sometimes utilized equidistant screw gradient. Crystalline polymer melt temperatures assortment is instead narrow, often utilized to reside equidistant mutations. (2) within tiny plastic material extruder, that consist of φ45 extruder screw is utilized in bottom net isometric type, screw the more compact element ratio, especially for only a tiny element within of the film games within of the insulation and protection layers, the extrusion rate. (3) method and gradient-depth thread with isometric son, screws, it is bigger than only a tiny element ratio, height, same exact thread, starting using the roots shallow to deep. Screw the thread of deep and shallow roots within of the wire, so the even more the quantity of Plastic extruder, without getting the durability within of the extrusion screw speed, excellent plasticization, extrusion equipments are frequently tiny and medium-insulating layer as well as the layer perfect screw jacket.
