Description

technical field [0001] The invention discloses a PPS plastic bar production equipment and process. Background technique [0002] PPS rod extrusion molding is to add granular materials into the barrel of the extruder from the hopper. Under the extrusion force of the screw rotation, the materials are conveyed and compacted forward through the friction between the inner wall of the barrel and the surface of the screw. The heating device and friction preheating on the outside of the barrel melt and plasticize under high temperature and high pressure conditions. Then, the continuously rotating screw pushes the molten material into the mold of the die, and the molten material extruded from the die is cooled and shaped into the desired PPS product. [0003] The previous PPS rod extrusion production line consisted of two parts: the main machine and the auxiliary machine, which are called extruder units; the main machine is an extruder, which consists of the following three parts: e...

AI Technical Summary

Problems solved by technology

[0005] The problems of the above process are: 1. The impact resistance of the bar is low; 2. The surface is not smooth and there are melting seams; 3. The internal stress of the bar is large; 4. The processing is easy to crack; 5. The production efficiency is low
