Product Specification

Bimetallic Extruder Screw Element for Wood Plastic Extruder for Twin Screw Extruder

1 . Factory introduction

Bimetallic extruder screw elements are made by bonding two or more metals together to create a single piece of equipment. This is done because different metals have different properties, and by combining them, you can create an element that has the best of both worlds.

For example, a bimetallic screw element for a wood plastic extruder might be made with a steel core and a layer of tungsten carbide on the surface. The steel provides strength and durability, while the tungsten carbide provides wear resistance and extends the life of the screw element.

Twin screw extruders use two screws that rotate in opposite directions to mix and melt materials. Bimetallic screw elements for twin screw extruders can be customized to meet the specific needs of the application, such as using different metals or coatings to optimize the mixing and melting process.

Overall, bimetallic extruder screw elements can improve the performance and longevity of extruders in various industries, including wood-plastic composite, food processing, pharmaceuticals, and more.

2 . The usage of Bimetallic Extruder Screw Element for Wood Plastic Extruder

Bimetallic extruder screw elements can be used in wood plastic extruders and twin screw extruders to improve the performance and durability of the extrusion process. These screw elements are made by welding together two different alloys, typically a high-wear resistance alloy and a high-corrosion resistance alloy, to create a composite structure that can withstand the harsh conditions of extrusion.

In wood plastic extrusion, bimetallic screw elements can improve the mixing and dispersion of wood fibers or particles in the plastic matrix, leading to a more homogeneous and consistent product. In twin screw extrusion, bimetallic screw elements can improve the conveying and melting of the polymer materials, as well as the mixing and homogenization of additives and fillers.

Overall, the usage of bimetallic extruder screw elements can lead to improved productivity, reduced downtime, and longer service life of the extruder equipment.

3 . The advantages 

The use of bimetallic extruder screw elements for wood plastic extruders offers several advantages, including:

a . Improved wear resistance: The tungsten carbide layer on the surface of the screw element provides excellent wear resistance, allowing it to withstand the abrasive nature of wood fibers and other materials.

b . Increased strength and durability: The steel core of the screw element provides strength and durability, allowing it to withstand the high temperatures and pressures involved in the extrusion process.

c . Better mixing and melting: The bimetallic screw element can improve the mixing and melting of the WPC materials, resulting in a more uniform and consistent output.

d . Longer lifespan: The combination of wear resistance and strength/durability can lead to a longer lifespan for the screw element, reducing maintenance costs and downtime for replacement.

e . Customizable options: Bimetallic extruder screw elements can be customized to meet the specific needs of the application, such as using different metals or coatings to optimize the mixing and melting process.

Overall, the advantages of using bimetallic extruder screw elements for wood plastic extruders can improve the efficiency and performance of the extrusion process, resulting in higher-quality WPC products with better mechanical properties.
