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

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.

For Bimetallic Process we also have our own advantages:

We use special alloy powders being sprayed and welded on the screw's ridge,
and
we use different alloy and welding methods for the screw of different functions.
