PRE-TREATMENTS

Mechanical or chemical

Mechanical pre-treatments

Where there is undesired damage, faults or irregularities in a surface, we recommend a mechanical pre-treatment, depending on the material and the subsequent surface treatment procedure. The surface finish ranges from matt to fully polished, as preferred.

We would be happy to advise on a suitable pre-treatment.

Chemical pre-treatments

Metal surfaces cannot simply be treated chemically, electrochemically or using electroplating without prior preparation. Contaminations, oxides or processing marks must be removed in a chemical pre-treatment. A clean surface on the work piece is a precondition for an even and stable surface finish.

Which chemical treatments are required? Ask your BWB customer advisor.
