1, High-speed, high-yield extrusion molds with high speed and high output enable investors to obtain larger output and high returns with lower investment. However, the high speed of the extrusion die screw speed also brings a series of difficulties that need to be overcome: if the residence time of the material in the screw is reduced, the material mixing and plasticization will be uneven, and the material undergoes excessive shearing, which may cause sudden temperature rise and heat of the material. Decomposition, difficult to control the extrusion stability will cause the geometry of the extrudate to fluctuate, the accuracy of the related auxiliary devices and control systems must be improved, and the wear of the screw and the barrel is intensified. High wear-resistance and ultra-high wear-resistant materials are required. Problems such as how to improve the life of the bearing at high speeds need to be solved.
2, high efficiency, multi-functional plastic extrusion mold efficiency is mainly reflected in high output, low energy consumption, low manufacturing costs. In terms of functions, screw extrusion die has not only been used for extrusion molding and mixing of polymer materials, but its use has been broadened into food, feed, electrodes, explosives, building materials, packaging, pulp, ceramics and other fields. In addition, the "one-step extrusion process" in which the kneading granulation and the extrusion molding process are combined into one is also worthy of attention.
3, large-scale and precision to achieve large-scale extrusion molding equipment can reduce production costs, which is more obvious in large twin-screw granulators, blown film units, pipe extrusion units. The major technical equipment required for the national key construction services, and the large-scale extrusion granulation unit of one of the three key equipments for large-scale ethylene projects have long relied on imports. Therefore, it is necessary to speed up the localization process to meet the development needs of the petrochemical industry. The precision can improve the gold content of the product, such as multi-layer co-extruded composite film, which requires precision extrusion, and as an important means to achieve precision extrusion. The melt gear pump must increase the intensity of development research.
4, modular and professional modular production can adapt to the special requirements of different users, shorten the development cycle of new products, and strive for greater market share; and specialized production can arrange the production of various system module components of extrusion molding equipment Even global procurement is very beneficial to ensure the quality of the entire period, reduce costs, and accelerate capital turnover.
5, Intelligent and networked extrusion molds in developed countries have adopted modern electronic and computer control technologies. Process parameters such as melt pressure and temperature, body temperature, main screw and feed screw for the entire extrusion process. The parameters such as the rotational speed, the feeding amount, the ratio of various raw materials, the current and voltage of the motor are detected online, and the closed-loop control of the microcomputer is adopted. Some companies have adopted online remote monitoring, diagnosis and control to control the network of extrusion molding lines. This is extremely advantageous for ensuring the stability of the process conditions and improving the accuracy of the product.
