Double Barrel for Conical Twin Screw Extrusion Machine

Product Overview

Description

Techincal Advantages of  

 Double barrel for parallel twin screw extrusion machine :

1.Advanced Nitriding Technology
2.Anti-corrosion and Wear-resisting Duplex Metal Spraying Technoloy

3.We use special alloy powders being sprayed and welded on the screw's ridge,and 

 use different alloy and welding methods for the screw of different functions.

 

 

Especially application:

 

 

Rubber,various high glass fiber, mineral fiber and PPA,PPS, PA6T, LCP,VO fire protection, ferrous power, magnetic powder and etc. Meanwhile,Used for PVC + 30% CaCo3, recylced plastic material,etc

Advantages

1. Parallel twin screw and barrel has the advantage of lower rotation speed, smaller shear   stress between the  small screw

2. Good plasticization, high productivity, small shear force, stable pressure , less wear and tear and low cost.

3. Parallel twin-screw and barrel is widely used in PVC products processing, especially for the production of PVC products with the output over 350Kg / h, because the parallel twin-screw and barrel costs less than conical twin-screw and barrel while it has more mature technology.

4. Parallel twin-screw and barrel is successfully applied in PVC plate, pipe, profile, pellet and mould, at the same time, it solved the technical problem of low foaming, high foaming, high filling, wear and corrosion.
