1. Common errors in the operation: Operators used to come to the factory in the morning to warm up the double screw extrusion extruder, and then go to do other things. This allows the twin screw plastic extruder to sit idle for several hours after being heated up to the designed temperature. This operation will cause the polymer to adhere to the screw and barrel, and the polymer material will continue to degrade and carbonize. Then, it is difficult to completely remove these materials when cleaning the machine. What is worse, once the two screw extruder starts to produce products, black spots will periodically exist in the materials extruded from the screw and barrel, polluting the products and leading to substandard product quality.

The mixing of plastics is to use an effective means or polymer compounding equipment to process multi-component raw materials into more uniform and practical particles. This process needs to go through, raw material pretreatment, feeding, plasticization, mixing, dispersion and distribution, exhaust, molding, etc. Some raw materials may occur chemical or physical reactions in the process. For twin screw machine, it has friendly operability, applicability and versatility.

The water-cooled twin screw extruder barrel is a heat exchanger. Like all heat exchangers, the water channel is prone to scaling and deterioration. Many operators notice that the cooling performance of a new extruder is much better than that of a twin screw extruder that is three or four years old.

There are many types of twin screw extruders, which can be classified from different angles, such as whether they have meshed or not, whether the grooves of the two screws are open or closed in the meshing area, whether the rotation directions of the two screws are the same or different.

The twin screw extruder machine is one of the core equipments for the production of plastic products, and is put into use in more and more plastic product manufacturers, and has played a huge role in it. With the advantages of high production efficiency, high yield and low energy consumption, the twin screw extruder machine, very popular among customers, is favored by more and more enterprises.

To improve consumption efficiency is one of the important purposes of the development of twin screw extruder, which is achieved by increasing screw speed, strengthening plasticization and mixing ability.
