Application & Characteristic :
The screw of the extruder equipped with barrer unit and mixing structure , and the barrel owns new style grooves . All of these offer good plastification and mixing effect . Special design of basket die head for HDPE(PP,ABS) large diameter pipe with thick wall offer lower melting temperature , good mixing , lower pressure of cavity and stable production .
Special design for sizing and cooling system by using film and water ring to cool HDPE (PP , ABS)material , which can fit for the requirement of HDPE . And the design can ensure the stabilit of diameter and roundness when producing the pipe with thick wall . Special design vacuum sizing tank can ensure the stability of size and roundness , speed controllers are used in extruder , haul off to offer stability and precision .
The whold line adopts PLC control system and large liquid crystal screen , which makes the operation very convenient . The line can be equipped with another extruder used for exruding the mark line .
