UCAR COATING

This coating is typically applied on seaming chucks and rolls and it extends their life up to three times. Surfaces coated with DIAMOND 98HRC have a very low friction coefficient, and as a consequence they have very high anti pickup features. Therefore, rubbing is reduced, and seams can avoid peeling.

PVD coating is commonly used on seaming chucks made of steel.

Seaming chucks and rolls made from tool steel are generally considered the industry standard for can factories, while canneries generally use stainless steel. Other types of steel are commonly used in the production of seaming chucks for Easy open covers, especially for those chucks that suffer from a weak chuck lip.

Depending on the client’s needs, seaming chuck lips can be provided with the following superficial finishing features smooth, sandblasted or knurled.
