High Efficiency Single Screw Extruder Use concept

Single screw extruder principle use characteristics of the concept of parameters

Single screw extruder principle

The last thread of the mouth began to be called the transport section of the material here can not be plasticized, but to warm up, pressure squeeze, the old extrusion theory that the material is loose, and later proved that the material is actually solid Plug, that is where the material is squeezed after a solid like a plug, so as long as the completion of the delivery task is its function.

Single screw extruder principle: the second paragraph is called the compression section when the trough volume gradually larger and smaller, and the temperature to achieve the degree of plastic material, where the compression generated by the transport section of three, here compressed to a, called screw Of the compression ratio - 3: 1, and some machines have changed to complete the plasticized material into the third paragraph.

Single screw extruder principle: the third paragraph is the measurement section here to maintain the plasticization temperature of the material, just like the metering pump as accurate and quantitative delivery of melt materials to supply the head, this time the temperature can not be lower than the plastic temperature, the general Slightly higher.

Single screw extruder mainly for the extrusion of soft, hard polyvinyl chloride, polyethylene and other thermoplastic materials, and the corresponding auxiliary (including forming the head) with a variety of plastic products can be processed, such as film, Plates, ribbons, etc., can also be used for granulation.

Plastic extruder design advanced, high quality, good plastic, low energy consumption, the use of involute gear drive, with low noise, smooth operation, bearing capacity, long life and other characteristics.

Single screw extruder use

Pipe extrusion: for PP-R pipe, PE gas pipe, PEX cross-linked pipe, aluminum-plastic composite pipe, ABS pipe, PVC pipe, HDPE silicon tube and a variety of co-extruded composite pipe.

Sheet and sheet extrusion: for PVC, PET, PS, PP, PC and other profiles and sheet extrusion. Other kinds of plastic extrusion such as silk, stick and so on.

Profile extrusion: adjust the extruder speed and change the structure of the extrusion screw can be applied to the production of PVC, polyolefin and other plastic profiles. Modified granulation: suitable for a variety of plastic blending, modification, enhanced granulation.
