Common operations in metal processing such as cutting, stamping, rolling and heat treatment all require the transport of metal sheets or sheets to the processing area. Rubber rollers protect the metal surface during the transport process to prevent scratches, dents or other surface defects. Therefore, the transport rollers are usually made of wear-resistant and high-temperature resistant rubber materials and are precision-processed to ensure that their surfaces are flat and smooth.

Forming and Extrusion:

During the forming and extrusion of sheets and sheets, rubber rollers are used to provide the necessary pressure and support to ensure that the metal material can be formed evenly without breaking or deforming. The elasticity and hardness of the rollers are essential to ensure the forming accuracy, while its pressure resistance and wear resistance determine the service life and stability of the rollers.

Surface Treatment:

Rubber rollers are also used for grinding and polishing metal surfaces to help remove surface defects and improve the finish of the metal. These rollers are usually made of wear-resistant rubber materials and are designed to adapt to different metal surface shapes to ensure uniform grinding and polishing effects.

Rubber Rollers in Plastic Processing

In the plastic processing industry, rubber rollers are widely used in various process flows, such as extrusion, calendering, coating and die-cutting. The diversity of plastic materials and the complexity of processing conditions have put forward various requirements for the performance of rubber rollers.

Extrusion and calendering:

During the plastic extrusion and calendering process, rubber rollers are used for the molding and transmission of plastic sheets or films. During the extrusion process, the plastic material is extruded from the mold and formed into the required sheet or film by high temperature and high pressure. The rubber roller needs to have high heat resistance and good wear resistance to cope with high temperature and high friction conditions, while ensuring the smoothness and uniformity of the finished surface.

Coating and lamination:

In the plastic surface coating process, rubber rollers are used to evenly apply the coating material to the plastic substrate. The coating roller is required to have good surface flatness and moderate hardness to ensure the uniformity and adhesion of the coating. In addition, the rubber material must have a certain chemical resistance to resist solvents or additives in the coating material.
