Techniques
Controlled immersion plating
Defined dipping of the belt into the electrolytes can be carried out with the help of this method whilst screens reduce the outflow areas to a minimum. A further development is the selective controlled immersion plating where the belt is moved selectively with the help of a dipping depth control.
Wheel technique
The continuous advancement of the selective wheel method allows us to refine sensitive jacks, springs, blades and lead frames in accordance with latest requirements. This method involves guiding the materials to be plated over a rotating wheel which is dipped into an electrolyte container. The exact refinement area is determined by the maskers revolving in the precision guides.
Belt technique
These cells are designed for specially stamped, pre-stamped and solid strips to create a one-face or double-face plating. This method involves the vertical passing of the conveyor by at least two rotating belts along an electrolyte jet facilitating selective plating by the shape and arrangement of the belt screen in operation.
Rainbow cell
This method makes it possible to plate one or several stripes on one or both sides. When this method is used the belt runs vertically along a punched foil and is covered on the rear with synthetic material whilst the front is passing the stretched foil. The jet application itself is arranged in such a way that the empty parts are optimally immersed.
Brush technique *
The brush technique we have developed can be used for the continuous throughput of blade and spring contacts and is a considerable cost saver; by using appropriately formed parts it eliminates high tooling costs for partial coverage. In this technique the precious metal is plated very precisely in the functional area of the components. The brush anode is available in different forms which enables very specific finishing variants.
Spot technique *
The precision of the spot plating method enables us to refine functional surfaces of pre-punched and embossed wrought products. The spot plating tool consists of a flexible masking chain rotating around a compact plating cell. During this process the belt is covered in soft material at the rear whilst the plating side is running over a crawler-type mask. This mask is punched with the relevant spot shapes and the electrolyte is jetted in during the cycle.
