Product Description

Barrel contains materials and screw. The twin-screw is the heart of the extruder, divided into the charging section (solid conveying zone), compression section(melting zone) and the homogenization section (the melt conveying zone) three parts. Put the material into the hopper ,under the action of a rotating screw, material was pushed on to direction of the nose. Material endures strong shear, mixing and calendaring in the barrel, In this process, Meanwhile, the physical states of material the evolve from glass state to the high elastic state ,eventually become sticky flow pattern .Because of its rotation, the powder or particle shape plastic was pushed to the former, so as to achieve compaction, melting and mixing purpose of homogenization,
