Pin type rubber extruders are generally used for the production of rubber pipes. Pin type extruders can perform secondary mixing when the material enters the material barrel, which not only ensures pressure, but also makes the quality of the produced products more uniform and stable.

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 metering section where the material maintains the plasticizing temperature, just like a metering pump that accurately and quantitatively delivers the molten material to the head. At this time, the temperature cannot be lower than the plasticizing temperature, usually slightly higher.

The single screw extruder 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, tubes, plates, ribbons, etc. It can also be used for granulation.

The plastic extruder is designed with advanced technology, high quality, good plasticization, low energy consumption, and adopts involute gear transmission. It has the characteristics of low noise, smooth operation, large bearing capacity, and long service life.
