Pretreatment

Pretreatment

Before any kind of metal can be deposited on a workpiece the piece has to be cleaned and degreased.

Ultrasonic cleaner

When cleaning surfaces the versatility of ultrasonic degreasing is getting visible. Highest grades of cleaning can be reached in comparatively short times. Advantages can be seen especially when cleaning geometric complex items. Ultrasonic is also effective on unapproachable areas where mechanical and manual cleaning like spraying and brushing fails. IWG Ultrasonic cleaners dissolve and suspend impurities, inhibit metal surfaces and saponify oils and greases.

Degreasings

A degreasing is necessary because a workpiece has to be free of oil and greases that aqueous electrolytes can wet the surface of the workpiece. Otherwise, an adherent electrolytic metal deposition is not possible.
