Product Description

Principle of single screw extruder:   The last thread of material port is called conveying section   In the past, the old extrusion theory believed that the material here was loose. Later, it was proved that the material here was actually a solid plug. That is to say, the material here was a solid like a plug after being extruded. Therefore, as long as the transportation task was completed, it was its function.     
The second section is called compression section. The volume of screw groove changes from large to small, and the temperature should reach the plasticizing degree of materials. The compression produced here is from conveying section 3 to one, which is called the compression ratio of screw - 3:1. Some machines also change, and the plasticized materials enter into the third section.     
The third section is the metering section, where the material maintains the plasticizing temperature, just like the metering pump to accurately and quantitatively transport the melt material to the machine head. At this time, the temperature should not be lower than the plasticizing temperature, generally slightly higher.    

SXT-I single screw extruder is mainly used for extruding soft, hard PVC, polyethylene and other thermoplastic plastics. It can process a variety of plastic products, such as film, pipe, plate, ribbon, etc., and can also be used for granulation in combination with corresponding auxiliary machines (including molding head).    

Main application of high speed single screw extruder    
Pipe extrusion: suitable for PP-R pipe, PE gas pipe, PEX cross-linked pipe, aluminum plastic composite pipe, ABS pipe, PVC pipe, HDPE silicon core pipe and all kinds of coextrusion composite pipe.   
Plate and sheet extrusion: suitable for extrusion of PVC, pet, PS, PP, PC and other profiles and plates. Other kinds of plastics extrusion, such as wire, rod, etc.    
Extrusion of profile: adjust the speed of extruder and change the structure of extrusion screw, which can be used to produce PVC, polyolefin and other plastic profiles.   Modified granulation: suitable for blending, modification and strengthening granulation of various plastics

This equipment is a small extruder for laboratory use, with its own motor and data measuring device, can be used independently, installation of different molds and with other auxiliary machines can be completed in the laboratory casting film, blowing film, pressure light or flow type impurity measurement, plastic granulation and other functions.
