The Plastic Extruder Industry Presents Three Major Development Trends

Pulished on Sep. 15, 2020

In recent years, the high speed and high output of extruders can enable investors to obtain larger output and high returns with lower investment. The high efficiency of plastic extruders is mainly reflected in high output, low energy consumption, and low manufacturing costs. In terms of function, the Single Screw Extruder is not only used for extrusion molding and mixing processing of polymer materials, but its use has been expanded to food, feed, electrodes, explosives, building materials, packaging, pulp, ceramics and other fields. In addition, the one-step extrusion process that combines the mixing and pelletizing and extrusion molding processes into one is also worthy of attention. After years of development, my country's plastic extruder industry has shown three major development trends:

Large-scale and sophisticated:

The realization of large-scale extrusion molding equipment can reduce production costs, which has more obvious advantages in large-scale Double Screw Plastic Extruders, film blowing units, and pipe extrusion units. The major technical equipment required for national key construction services, and the large-scale extrusion pelletizing unit, one of the three key equipment supporting large-scale ethylene projects, has long been dependent on imports. Therefore, the process of localization must be accelerated to meet the development needs of the petrochemical industry. Precision can increase the gold content of products. For example, multi-layer co-extruded composite films require precision extrusion. As an important means to achieve precision extrusion, melt gear pumps must increase their efforts in development and research.

Modularity and specialization:

Modular production can adapt to the special requirements of different users, shorten the research and development cycle of new products, and strive for a larger market share; while specialized production can arrange fixed-point production and even global procurement of various system module components of extrusion molding equipment. Ensuring the quality of the entire period, reducing costs, and accelerating capital turnover are all very beneficial.

Intelligent and networked:

Extruders in developed countries have generally adopted modern electronic and computer control technology. The process parameters of the entire extrusion process, such as melt pressure and temperature, temperature of each section of the fuselage, main screw and feeding screw speed, and feeding volume, are widely used. The parameters such as the ratio of the raw materials and the current and voltage of the motor are detected online, and the microcomputer closed-loop control is adopted. Some companies have adopted online remote monitoring, diagnosis and control, and network control of extrusion molding production lines. This is extremely beneficial to ensure the stability of the process conditions and improve the accuracy of the product.

Companies engaged in the Plastic Extruder Industry should fully understand the characteristics of the industry and the development trend of the industry, combine the advantages and disadvantages of their own companies, spot the industry development trend, create development opportunities, and always prepare for the transformation and upgrading of the company. In addition to the three development trends mentioned above, the industry also pointed out that cold-feed extruders will also become the development trend of the extruder industry, because compared with hot-feed extruders, cold-feed extruders are technically And the operation is more advanced and convenient, and the quality of the products produced is relatively good. However, the design of the extrusion process of the cold feed extruder is still complicated at the moment, and it requires professional operators to judge and analyze.
