Plastic & Rubber Machinery Parts Screw And barrel For Twin
Screw Extruder
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.
Some common applications of plastic and rubber machinery parts
screw and barrel for twin-screw extruder include:
1. Compounding: The mixing and blending of different plastic or
rubber materials to create a new compound with specific properties.
2. Extrusion: The process of melting and shaping plastic or rubber
materials into a specific shape, such as a pipe, profile, or sheet.
3. Pelletizing: The process of shaping melted plastic or rubber
into small pellets for later use in manufacturing.
4. Recycling: The processing of plastic or rubber scrap materials
into new products.
5. Co-extrusion: The process of combining two or more different
plastic or rubber materials during extrusion to create a new
product with specific properties.
6. Foaming: The process of creating a cellular structure in plastic
or rubber materials to reduce weight and improve insulation
properties.
Overall, plastic and rubber machinery parts screw and barrel for
twin-screw extruder are essential components in the plastics and
rubber industries, and are used in a wide range of applications to
produce a variety of products with diverse properties and
characteristics.

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.
