Advantages of plastic extruder:
1. Large scale and precision
The large-scale plastic extruder can reduce the production cost, which is more obvious in large-scale twin-screw plastic granulation unit, film blowing unit, pipe extrusion unit and so on. The major technical equipment required by the state's key construction services and one of the three key equipment for large-scale ethylene project, large-scale extrusion granulation unit, which is one of the three key equipment for large-scale ethylene project, has been imported for a long time. Therefore, it is necessary to accelerate the process of localization to meet the development needs of petrochemical industry.
2. Modularization and specialization
The modular production of plastic extruder can adapt to the special requirements of different users, shorten the research and development cycle of new products, and strive for more market share; while the specialized production can arrange the fixed-point production and even global procurement of various system module components of extrusion molding equipment, which is very beneficial to guarantee the whole period quality, reduce costs and accelerate capital turnover.
3. Intellectualization and networking
Modern electronic and computer control technology has been widely used in plastic extruders in developed countries. The process parameters of the whole extrusion process, such as melt pressure and temperature, body temperature of each section, rotational speed of main screw and feeding screw, feed rate, ratio of various raw materials, current and electric pressure of motor, etc., are detected on-line, and closed-loop microcomputer control is adopted. This is very beneficial to ensure the stability of process conditions and improve the accuracy of products.
4. High efficiency and multi-function
The high efficiency of plastic extruder is mainly reflected in high output, low energy consumption and low manufacturing cost. In terms of function, screw plastic extruder has not only been used for extrusion molding and mixing processing of polymer materials, but also has been extended to food, feed, electrode, explosive, building materials, packaging, pulp, ceramics and other fields.
