Detailed Product Description

Twin Screw Extruder Screw and Barrel Converying Element for Famous Brand Machine / Professional Plastic Machine

1 . Description
An extruder screw element, also known as a screw segment, is a key component of an extrusion machine. It is responsible for melting and conveying the raw material (such as plastic pellets) down the barrel of the extruder where it is melted, mixed, and transformed into the desired shape or form. The screw elements are typically designed with varying pitch, depth, width, and channel geometry to optimize the melting, mixing, and conveying functions. Different types of screw elements are used depending on the specific requirements of the extrusion process and the properties of the material being processed.

Plastic and rubber machinery parts screw and barrel for twin-screw extruder are used in a variety of applications in the plastics and rubber industries. These components are designed to convey, mix, and melt plastic or rubber materials, and are crucial to the performance and efficiency of twin-screw extruder machines.

Twin-screw extruder screw and barrel conveying elements are used in a variety of professional plastic machines and are designed to convey plastic materials through the extruder while providing proper mixing and melting. These conveying elements are specifically designed for use in twin-screw extruders and are often made from high-quality materials such as nitride steel, bimetallic alloys, and other wear-resistant materials.

Many famous brands in the plastic processing industry use twin-screw extruder screw and barrel conveying elements as part of their machines, including:

1. Coperion: A global leader in compounding and extrusion systems, Coperion offers a range of twin-screw extruders for use in the plastics and rubber industries.

2. KraussMaffei: A German manufacturer of plastics processing equipment, KraussMaffei produces a range of twin-screw extruders for use in various applications.

3. Leistritz: A leading manufacturer of twin-screw extruders for the plastics and pharmaceutical industries, Leistritz offers a range of high-performance extruders and components, including screw and barrel conveying elements.

4. Bühler: A Swiss company specializing in process engineering and equipment for the food, feed, and advanced materials industries, Bühler offers a range of twin-screw extruders for use in plastic processing.

Overall, twin-screw extruder screw and barrel conveying elements are essential components in many professional plastic machines and are used in a variety of applications to produce high-quality plastic products.

5 . Comparsion of the output (LDPE)

Pressure is generated if resin passes over the barrier, forcing any air in the melted resin back to the feed side and effectively preventing the intrusion of air bubbles on the sub flight side. This is highly effective with resins that generate bubbles such as PS, PA, PET and EVOH.

Bimetallic Treatment of Screw

The bimetallic screw for extruder twin screw is a kind of screw spray welding a 2~3mm-thick alloy coat on the screw flight of output area for the screw . The Bimetallic treatment has excellent corrosion resistance, abrasion resistance and high working temperature. And its useful service life is greatly improved contrast to the common nitrided screw.
