Twin Screw Extruder

Introduction

Twin screw extruder is the classic machine used for the plastic extrusion process when two or more ingredients are blended or Twin Screw Extrudercompounded. The process is greatest suited when extruding reactive polymeric materials. Twin screw extruder is particularly helpful in the production of rigid PVC and wood fiber blends. In this technique two screw rotates with or against each other and have special mixing feature equivalent to kneading block and forward and reverse capabilities, etc.

Types of Machines

Numerous range of screw extruder are manufacture from premium quality materials. Machine with sophisticated features are available at reasonable rates. Customized twin screw extruders are additionally manufactured as per the requirement of consumers in numerous industries. Machines are available which can be designed to be easily synchronized with drives of extruder and haul off leading to high output at low screw pace and less consumption of power, straightforward operation, etc.

New and advanced range of twin screw extruder are equipped in the market. One such modern product is the conical twin screw extruder for dual conduit pipe that is capable of producing twin pipe out of one mould. And hi-tech machine is the kneading extruders which can be crucial as a result of their various applications in industries and seriousness economic. This type contains single-screw and multi-screws.

Advantages

In a twin screw or multi screw extruder there are screws. Even is a modestly sized extruders, these screws are highly environment friendly Twin Screw Extruderdevices capable of process a number of tons of plastic per hour. The flexibility of dual screw extrusion equipment allows this operation to be designed specifically for the formulation being processed. For instance, the 2 screws may be corotating or counterrotating, intermeshing or nonintermeshing. In addition, the configurations of the screws themselves could also be diversified utilizing forward conveying elements, reverse conveying parts, kneading blocks, and different designs as a way to achieve particular mixing characteristics.

Application

Twin-screw extruders are applicable in industries because of their high capacity. Extruders with twin-screw and quick distance between screws have high capacity and good thermal and mechanical stress. Twin screw machines are used for manufacturing RPVC pipes, RPVC dual conduit pipe, PVC profile and PVC compounding. These machines has high output and low energy consumption features.
