Twin Screw Extruder

Sharing is caring!

Introduction

Twin screw extruder is the traditional machine used for the plastic extrusion process when two or more ingredients are mixed or Twin Screw Extrudercompounded. The process is greatest suited when extruding reactive polymeric materials. Twin screw extruder is particularly useful within the production of rigid PVC and wood fiber blends. In this technique screw rotates with or in opposition to one another and have particular mixing feature such as kneading block and forward and reverse capabilities, etc.

Types of Machines

Diverse 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 also manufactured as per the requirement of shoppers in different industries. Machines are available which are designed to be easily synchronized with drives of extruder and haul off resulting in high output at low screw velocity and less consumption of energy, straightforward operation, etc.

New and advanced range of dual screw extruder are provided within the market. One such revolutionary product is the conical twin screw extruder for twin conduit pipe that’s capable of producing twin pipe out of 1 mould. And hi-tech machine is the kneading extruders which are crucial on account of their varied 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 permits this operation to be designed specifically for the formulation being processed. For example, the 2 screws may be corotating or counterrotating, intermeshing or nonintermeshing. In addition, the configurations of the screws themselves could also be diversified using forward conveying components, reverse conveying parts, kneading blocks, and different designs with the intention to achieve specific mixing characteristics.

Application

Twin-screw extruders are applicable in industries because of their high capacity. Extruders with twin-screw and short 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.
