After more than 100 years of development, plastic extruders have been derived from the original single screw twin screw, multi-screw, and even no screw. Plastic extruder (main machine) can be used with pipes, films, materials, monofilaments, flat yarns, packing belts, extruded nets, plates (sheets), profiles, granulation, cable coating, etc. Matching, forming a variety of plastic extrusion molding lines to produce a variety of plastic products. Therefore, plastic extrusion molding machines are one of the most widely used models in the plastics processing industry, now or in the future.
In China’s plastic machinery market, plastic extruders, as an important processing equipment, play an important role in the processing of packaging belts, plates, films, granulation, profiles and other products. The development of extruder processing technology has always been the focus and hot spot of the development of plastic processing industry. For a long time, the development of its processing technology has directly affected the development of the plastics processing industry.
After decades of accumulation and precipitation of technology, China’s plastic extruder technology has made certain breakthroughs. With the development of the plastics processing industry towards the limit, precision and high speed, the related plastic extruders also exhibit the characteristics of high efficiency, multi-function and low energy consumption.
Modular specialization
Nowadays, with the development of plastic extruders, there are different types and functions of extruders in the plastics processing market. A wide variety of extruders can be dazzling. As a result, the factory has adopted a modular production method for the extruder. This production method not only can adapt to the requirements of different plastic products, but also can meet the special needs of different users, so that users can get the products they want in the first time. In addition, this production method can shorten the development cycle of new products and strive for a larger market share. The specialization in the production process can arrange the various system module components of the extrusion molding equipment to be fixed-point production or even global procurement, which is very beneficial to ensure the quality of the whole period, reduce the cost and accelerate the capital turnover.
High efficiency
At present, the characteristics of high output and low energy consumption of plastic extruders have led to the development of high efficiency and high speed. Take the same direction twin screw extruder as an example. The extruder uses a high torque gearbox. This type of gearbox has stable performance, long life and large load carrying capacity. The gearbox has a specific torque of 14 Nm/cm3 and a maximum output speed of 1800 r/min. In addition, increasing the diameter of the screw can also increase the productivity of the extruder. When the screw diameter is doubled, the productivity of the extruder can be increased several times, thereby increasing the productivity of the extruder.
Intelligent network
Today, plastic extruders in many developed countries have been artificially intelligent, and modern electronic and computer control technologies are widely used. The addition of smart technology not only enables high product precision, but also makes the entire processing process more stable. Although China’s current extruders are not as intelligent as foreign countries, with the continuous innovation of technology, in the field of intelligence, China’s extruders have also achieved certain results. For example, the application of an intelligent temperature control system and an intelligent monitoring system for an extruder.
In the future, China’s plastic extruders will continue to follow the international development trend, innovate and upgrade their own technology, and strive to develop more efficient, stable, safe and quality extruders according to market demand.
