Plastic extrusion and film production are among the most common applications for industrial chill rollers. In these production processes, plastic materials are usually extruded by heating and then need to be quickly cooled before forming and final shaping to ensure a smooth surface and uniform thickness of the product.

If the roller surface is not clean enough or there are pollutants such as oxide layer and oil before electroplating, it is difficult for the chrome layer to firmly bond with the substrate. In this case, the chrome layer of the chrome plated roller is prone to shedding during use.

The high hardness of the chrome plating layer enables it to maintain a good surface state when facing high-intensity friction, and it is not easy to be worn or scratched. Even after long-term use, the surface of the chrome plated roller can still remain smooth and uniform.
