Chucks - Import export

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

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.

This set of calibration wires is used to adjust the correct position of the seaming rolls in relation to the seaming chucks.

Ceramic ball bearings are fully resistant to corrosion as both the external and internal races are made of stainless steel, while the inner cage is made of plastic material, which is resistant against high temperatures. Thanks to the low friction of the ceramic balls, the seaming rolls require a reduced lubrication – up to five times less than standards. This saves time for the operators and the machine downtime, allowing increased production.

Thanks to our experience in this industry, Imeta has developed new assemblies for some older seaming rolls. These include the “Easy System” type roll for the Angelus P Series, and the “Super Seal” type roll for any seaming machines. These can reduce roll maintenance time and costs.

Ceramic seaming rolls can increase production efficiencies and reduce machine downtimes by eliminating or significantly reducing many problems deriving from wear, corrosion and superficial damage. There is a low friction coefficient and they are approved by the USFDA.

UCAR plating is applied on the lips of the seaming chucks in order to offer high wear resistance features, besides friction with the parts it is in contact with.

This chromium plating is used for some applications, such as seaming rolls for filters and deepdrawn aluminum cans. It guarantees a very good wear resistance and a low friction coefficient.

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.

CVD coating is typically used for Stoody seaming rolls and chucks. Its main feature is its superior adhesion to the base steel, which provides a high resistance against wear and corrosion.

This is a highprecision instrument to adjust the pin height. It can also be used as a scriber, as a gauge for parallel lifters, for distance measurements, as well as an adjustable parallel or support for indicators.
