Bimetallic Nitrided Conical Twin Screw Barrel For WPC PVC PE Industry

Bimetallic Nitrided Conical Twin Screw Barrel For WPC PVC PE Industry

1.Product Introduction

Conical twin-screw extruder is composed of barrel, screw ,gear transimission system,measurable feeding,vacuum system,heating,cooling and electronic control components.

It is mainly used in plasticizing,extruding and forming PVC pipe ,plate,sheet,film,profile,and granule,etc

2.Main Advantages

1– Low shearing rate, uneasy degradation,plasticization uniform and agglomeration.

2– Reliable quality ,wide application range and long servicing life.

3– Automatic temperature control, vacuum gas exhaustion, oil cooled screws.

4— forced feeding and self-cleaning mechanism.
