Guyson Blast Cabinet Etches Busbars

Guyson blast cabinet provides a blast etched surface, on a range of high voltage busbars, to improve adhesion of a special non-conductive coating.

Guyson International, the UK’s foremost industrial finishing equipment manufacturer, has recently installed a specially configured Guyson Euroblast® 7PF (Pressure Fed) blast cabinet into one of the world’s leading designers and manufacturers of switchgear and instrumentation. The cabinet is to provide a blast etched surface, on their range of high voltage busbars, to improve adhesion of a special non-conductive coating.

The company’s existing blast cabinet system had suffered from several operational problems, so the search was on for an improved solution with better blast media handling and operator efficiency. With three tenders in place, the operators and Maintenance Manager visited Guyson’s ‘Component Finishing Centre’ at Skipton to try out Guyson’s proposed manual blast system on their components. “All of the operators bought into the Guyson blast unit straight away and it was their unanimous preferred option” said their Maintenance Manager.

The chosen Euroblast 7PF blast cabinet is from Guyson’s premier industrial quality range and delivers exceptional component access, with doors opening to the front, top and side, and so facilitates easy loading of components. In fact, with the blast chamber being oblong rather than square in shape, it proves a popular choice amongst customers for blasting longer components. But due to the length of some of their copper, silver and tin electro-plated busbars being even longer than the width of the Euroblast 7PF cabinet; a special cabinet design was needed.

This was drawn up, in 3D CAD, by Guyson’s in-house design team and incorporated a 700 mm extension box on the left hand side of the cabinet, supported by legs, and a cut out profile in the right hand door (with blanking door to prevent media escape) so that longer busbars can be fed into the cabinet for selective blast etching. The remainder of the pressure fed blast system includes a Guyson’s G27 pressure pot, C800 twin cartridge dust collector and a ‘High Efficiency’ cyclone. This latter item is designed to remove the majority of dust and fines from reaching the dust collection unit, thus extending the life of the filter cartridges between changes.

Guyson Euroblast PF systems are designed for speed, giving faster cleaning times (up to four times faster than suction fed or venturi systems) to meet higher production requirements and at peak demand this blast system can be working for the entire length of a full shift so it is necessary that the blast system quickly produces a perfectly keyed surface for the powdered coating to adhere to in the oven.
