Product Introduction
Second hand extruder machine can be divided into single-screw extruder, twin-screw extruder and multi-screw extruder according to the number of screws. SJ 65C Single-screw extruder occupies an important position both as plasticizing granulation machinery and molding processing machinery. In recent years, single-screw extruder has developed greatly.
The twin-screw extruder has good feeding characteristics, is suitable for powder processing, and has better mixing, exhaust, reaction and self-cleaning functions than the single-screw extruder. It is characterized by its advantages when processing plastics and blends with poor thermal stability.

Features
● Modularity and specialization
Second-hand extruder machine. 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 a larger market share; and specialized production can arrange fixed-point production and even global procurement of various system module components of extrusion molding equipment, which is very beneficial to ensure the quality of the entire period, reduce costs, and accelerate capital turnover.
● Efficient and versatile
The high efficiency of plastic extruder is mainly reflected in high output, low energy consumption and low manufacturing costs. In terms of function, screw plastic extruder has not only been used for extrusion molding and mixing processing of polymer materials, but its use has been broadened to food, feed, electrodes, explosives, building materials, packaging, pulp, ceramics and other fields.
● Large-scale and refined
Realizing the large-scale plastic extruder can reduce production costs, which has more obvious advantages in large twin-screw plastic granulation units, film blowing units, and pipe extrusion units. The major technical equipment required for national key construction services, and the large-scale extrusion granulation unit, one of the three key equipment supporting large-scale ethylene projects, have long relied on imports. Therefore, the localization process must be accelerated to meet the development needs of the petrochemical industry.
● Intelligence and networking
Second-hand extruder machine in developed countries have generally adopted modern electronic and computer control technology to detect the process parameters of the entire extrusion process such as melt pressure and temperature, the temperature of each section of the fuselage, the speed of the main screw and the feeding screw, the amount of feed, the ratio of various raw materials, the current and voltage of the motor and other parameters online, and use microcomputer closed-loop control. This is extremely beneficial to ensure the stability of the process conditions and improve the accuracy of the product.
