The purpose of the rough grinding stage is to remove large scratches, oxide layers and other obvious stains on the surface of the industrial chrome plated roller. Use coarser sandpaper (such as 200 mesh or lower) and a polishing machine for preliminary grinding.

The hardness range of hydrogenated nitrile rubber rollers is usually between 50A and 90A. Specifically, hydrogenated nitrile rubber rollers with lower hardness (such as 50A-60A) are mainly used in situations requiring higher elasticity and better adaptability, while hydrogenated nitrile rubber rollers with higher hardness (such as 80A-90A) are suitable for environments with greater pressure and high temperature.

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.
