Ceramic coating alloy screw barrel

The screw and reinforcement process was developed for users of stone plastic composites and PVC rigid vinyl plank extruders with fillers above 600%. As a wear-resistant solution for twin screws, chrome plating should be familiar to users. When processing rigid vinyl plank materials such as stone-plastic PVC, a chrome-plated screw is still not strong enough to resist wear. In order to replace chrome on chrome-plated screws, we are upgrading them with a ceramic tungsten alloy that has enhanced strength and performance. In place of chrome plating, a full coating is applied to the screw’s key wear-flight areas. A complete ceramic tungsten coating covers the underside of the screw flights, including the sides and surface. The ceramic tungsten alloy screw has a more rigid metal surface and is more wear-resistant, according to user feedback.

The ceramic tungsten alloy is 0.05-0.1 mm thick and tightly coated on the screw surface to ensure that it does not flake off during use and affect the quality.

A set of ceramic tungsten alloy screws made from nitrided steel with a bimetallic alloy process to strengthen wear-prone areas. And a ceramic tungsten coating is applied to the screw’s key strengthening areas.

Advantages of HUACHEN ceramic coating alloy screw

1. Fine material reduces microcracking and porosity in chrome plating

2. Improves corrosion resistance

3. improve resistance to abrasion

4. increase the hardness of the plated layer
