The new high efficiency screw is composed of a separate screw and an optimized mixing element, and its barrel is an optimized design of a grooved barrel and an extended feeding section.
Through the combination of separate screw and grooved barrel, the following advantages can be obtained:
1) The material melting process is optimized, thus increasing the extrusion yield and realizing the extrusion of the material melt at a lower temperature.
2) Through the specific shear action in the isolation gap, the material achieves good homogenization.
3) The melt plasticization process is controlled, that is, only particles smaller than the isolation gap can enter the melt channel.
Applicable materials:
PVC(PVC-U, SPVC), PE, PP, ABS, PC, PA, PET, PTFE and so on
Scope of application:
Universal screw: water pipe, gas pipe, threading pipe, transparent hose, medical hose, PP-R pipe, POM pipe, etc
Efficient type screw: single (double) wall bellows, solid wall pipes, steel belt pipes, etc
Exhaust screw: transparent PMMA tube, PC tube, PC lampshade, ABS tube, etc
Special engineering plastic screw: PTFE tube, PVDF tube, etc
It provides a wide range of processing for different materials, which is suitable for all kinds of polyolefin raw materials, especially for HDPE, PP, ABS pipe materials.
