Guyson Grit Blaster For Cleaning PVD Shields

 
SKIPTON, U.K. - March 10, 2022 - PRLog -- Guyson International, the UK's leading manufacturer of industrial finishing equipment, has recently delivered its latest Guyson Euroblast® 7PF 'Pressure Fed' manually operated blast cabinet into a tool coating company for reclaiming expensive vacuum coating shields used in the Physical Vapour Deposition (PVD) coating process. The Euroblast size 7 cabinet has proven to be the favoured choice of many of the world's foremost cutting tool coating companies for this application.

Using physical vapour deposition, a base component (cutting tools such as drills, cutting hobs, end-mills etc.) is covered with a hard-wearing or heat-resistant material to extend the product's performance capabilities.

During the PVD process, which is performed in a vacuum chamber, the coating is not only applied to the product itself but also coats the internal walls and windows of the chamber with an overspray of thin-film coating which can be difficult to remove, especially in situ. Therefore, most chambers are equipped with internal shields that protect the walls and windows etc. However, over time, these shields also become heavily coated and develop a multi-coloured pattern on them and the surface coating can start to fragment and crack, which can then start to negatively impact the PVD coating process unless they are cleaned.

The Euroblast 7PF blast cabinet is a popular choice for cleaning up these shields due to its wide cabinet size allowing it to accommodate a larger number of shields, usually up to a maximum size of 30 cm x 20 cm. Importantly, the larger armholes allow the operator to reach the full shield edges from a standing position. An adjustable gun support arm enables the operator to put the blast gun in the holder which then leaves both hands free to manipulate the component under the blast stream.

Guyson offers two types of pressure pots: 55-litre and 27-litre, depending on the intended blast cycle and the volume of components, to generate the blast stream within the blast chamber. Users are recommended to use a cyclone reclamator to separate re-usable media from the dust, blast debris, and undersized media in their pressure fed blast systems.  And the entire system is completed with a Guyson dust collector, matched to the pressure pot and blast cabinet size for collecting dust-laden air from the blast cabinet.
