Functional Electroplating

Proven traditional processes meet innovative and sustainable technologies

Innovation is often described as "reaching new goals by new means." For SurTec innovation also means re-evaluating existing processes and realising dedicated improvements for leading-edge applications.

With this approach, SurTec succeeded in upgrading traditional processes – such as Zinc and Zinc-alloy electroplating – to highly innovative applications with only slightly modified process parameters.

Alkaline Zinc Process for Ferrous Metals

SurTec 704 is a well-proven process for zinc plating of ferrous metals. It deposits well passivable zinc layers with adjustable gloss and is also very suitable for the zinc plating on parts with difficult shapes. 

Depending on the requirements for corrosion protection and appearance, SurTec also offers the optimum passivation and top coat for your application.

Modular, Alkaline Zinc/Nickel Process for all Applications

For more than ten years SurTec 717 has been one of the leading processes in its category. This is not least due to the extremely stable electrolyte and the extraordinarily high metal deposition rate.

Chromium(VI)-free Thick Layer Passivation for Zinc and Zinc Alloys

SurTec 680 Chromiting is a universal process for zinc and zinc alloys. It meets highest requirements regarding heat resistance and corrosion protection whilst allowing for a waste water free application. 

There is also a Chromiting version available which is low in cobalt.

Thick Layer Passivation

Low-temperature Chromiting

SurTec 688 has been developed for working at lower temperatures (25-35°C) and is suitable for alkaline and acid zinc coatings. It produces stable haze-free coatings.

For a Long-lasting and Reliable Connection

On average, about 2000 fasteners are installed in a common passenger car. They are often invisible but always essential. Screws and nuts hold car or other machinery components together, they have to resist extreme environmental impacts and guarantee a smooth and safe driving experience.

Of course, it's not only vehicles where fasteners are essential. In fact, the industry is also strongly tied to the production of aircrafts, appliances, agricultural machinery, commercial construction, and infrastructure. More than 200 billion fasteners are used per year in the U.S., 26 billion of these by the automotive industry.
