Price of single screw extruder

Price of single screw extruderIt is mainly used for extruding thermoplastic materials such as soft and hard polyvinyl chloride, polyethylene, etc. It can be used in conjunction with corresponding auxiliary machines (including molding heads) to process various plastic products, such as films, pipes, plates, ribbons, etc. It can also be used for granulation.

Price of single screw extruderAdvanced design, high output, good plasticization, low energy consumption, using involute gear transmission, with characteristics such as low noise, smooth operation, high bearing capacity, and long service life. DM screws can also be made according to the requirements of permanent use.

Principle:

The thread behind the material mouth is called the conveying section where the material is required not to be plasticized, but to be preheated and compressed. In the past, the old extrusion theory believed that the material here was loose, but later it was proven that the material here was actually a solid plug, which means that the material here is solid like a plug after being compressed. Therefore, as long as the conveying task is completed, its function is fulfilled.

The principle of a single screw extruder: When the second stage is called the compression stage, the volume of the screw groove gradually decreases from large to small, and the temperature needs to reach the degree of material plasticization. Compression occurs in this stage from the conveying stage three, where it is compressed to one, which is called the compression ratio of the screw -3:1. Some machines also have changes, and the material that has completed plasticization enters the third stage.

Principle of single screw extruder: The third stage is the measuring stage, where the material maintains the plasticizing temperature, but it is likemetering pumpIn order to accurately and quantitatively transport molten materials to supply the machine head, the temperature should not be lower than the plasticizing temperature, usually slightly higher.
