Surface treatment

For long-lasting performance of spring elements

Surface treatment

For particularly high-quality springs, Bohnert offers a wide range of surface treatments, from galvanizing with precious metals such as gold, silver, copper, zinc and nickel to greasing, flocking and coloring. In addition, you can also individually determine the color and conductivity of the spring elements, surface protection or noise minimization.

Galvanic surfaces are used to improve the conductivity, grounding, contact transfer, reduction in resistance and color coding of the spring elements. With the application of metallic deposits by electrochemical deposition we finish your springs to meet your requirements.
