Chamber pretreatment

Pretreatment is a crucial step in electroplating. During the manufacturing of components, oils and fats are used to facilitate the machining of the workpieces and temporarily protect the metal surface from corrosion. Before the electroplating process, these oils and fats must be removed from the workpiece to be plated, as any residues can lead to coating defects. A thorough pretreatment is an important prerequisite for a high-quality coating. Depending on the process sequence, pretreatment may involve multiple steps. In this group of processes, Schlötter offers boiling or hot degreasing, electrolytic degreasing for a variety of base materials such as steel, copper, brass, as well as pretreatments for aluminum and zinc die casting.

Singeing consists in burning off projecting fibres, without damaging the fabric, in order to obtain a smooth surface and minimise pilling. This technique is commonly used on natural fibre fabrics and synthetic and natural fibre blend fabrics.

The purpose of bleaching is to remove natural colouring matters with the production of a pure white material. Washing : This step consists of cleaning the fabric of any excess chemical residues from the previous steps.
