Twin Screw Extruder

Introduction

Twin screw extruder is the traditional machine used for the plastic extrusion process when or more ingredients are mixed or Twin Screw Extrudercompounded. The process is greatest suited when extruding reactive polymeric materials. Twin screw extruder is especially useful in the production of rigid PVC and wood fiber blends. In this method screw rotates with or against each other and have special mixing function comparable 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 options are available at reasonable rates. Custom-made twin screw extruders are additionally manufactured as per the requirement of consumers in several 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 speed and less consumption of energy, simple operation, etc.

New and advanced range of twin screw extruder are provided in the market. One such modern product is the conical twin screw extruder for dual conduit pipe that’s capable of producing twin pipe out of one mould. And hi-tech machine is the kneading extruders which might be crucial resulting from 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 two screws. Even is a modestly sized extruders, these screws are highly environment friendly Twin Screw Extruderdevices capable of process several tons of plastic per hour. The flexibility of dual screw extrusion equipment permits this operation to be designed specifically for the formulation being processed. For example, the 2 screws could also be corotating or counterrotating, intermeshing or nonintermeshing. In addition, the configurations of the screws themselves could also be assorted using forward conveying elements, reverse conveying components, kneading blocks, and different designs with the intention to achieve particular mixing characteristics.

Application

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