The brush technique is a well-known and proven process for very precise and cost-saving application on both flat and curved contacts. This technique is particularly well suited for finishing stamped and/or embossed tops and raised areas.
Through a very precise adjustment of the finishing zone, the brush technique provides a much more accurate plating of stamped strips than the belt or wheel technique.
The pre-stamped strip is guided with the zone to be plated over the brush cloth of the finishing cell. This method allows the precious metal to be applied in a very targeted manner in the functional area of the strip. Different designs of the anode width and shape enable a precisely defined plating profile.
Thanks to the fast set-up times, the brush technique is very cost-effective and flexible to use. No costs are incurred for item-specific tools or for specially designed masking pieces used to provide partial coverage. Since one-sided selective plating is possible, more than 50% of precious metal can be saved compared to the immersion process.
