Parallel Compounding Twin Screw Extruder For General Plastic HPL77 Model

High output Co Rotating Parallel Twin Screw Extruder Machine of HPL77

1 . Introduction :

Twin screw extruder machine is widely used for plastic pipe extrusion line , plastic profile extrusion line and

plastic sheet extrusion machine line . It is used for feeding , transporting , melting plastic material and make

sure that plastic material out from different extrusion moulds .

2 . Aplication :

For Co-rotating parallel twin screw extruder :

a . general plastic

b . ABS , PA , PC , PE , PET , PP , PS , etc

c. PA + GF ( glass fiber )

d . modified enginnering plastics

e . flame - resistant reinforced plastics

3 . Main Component :

Gearbox : It's used for connecting the screw and motor . when the twin screw extruder machine is running

at high speed , we need the gearbox to control the speed of the machine . It's neccesary that choose a

good brand .

Screw and barrel : The design of screw structure of screw should be paint capacity and quality , now

design of screw is becoming standardization and homogenization on the market , quality of screws are

stable for most suppliers now .

Casting heater : It is used for heating barrel and screw which ensure mixed PVC resin material can be

plasticizing and melting under the suitable temperature when mixed PVC resin material comes into inside of

barrel and transported forward by screw.

Control cabinet : It is used for control whole twin screw extruder running by switchs or PLC programes

according to different circults control required .
