Pre-treatment

Pre-treatment is an important step in electroplating. Oils and greases are used in the manufacture of components to facilitate the processing of the workpieces and to temporarily protect the metal surface from corrosion. Prior to electroplating, oils and greases must be removed from the parts, as residues can lead to defective coatings. A thorough pre-treatment is an important prerequisite for high-quality coatings. Depending on the process sequence, the pre-treatment can also include several process steps. For this application, Schlötter offers a range of soak degreasers as well as electrolytic degreasers for a variety of base materials such as steel, copper, brass as well as pre-treatments for aluminum and zinc die-casting.

Pre-treatments are used for:

Functional and ecorative coatings (GMF), PCB manufacturing, electronics and cathodic corrosion resistance coatings (CRC)
