Dip Spin Coatings (Coating)
A non-electrolytic method used to apply a protective or decorative finish to fasteners, especially suitable for bulk application to many small parts. In this process, fasteners are fully submerged (dipped) in a coating solution, then quickly spun in a centrifuge. The spinning action removes excess coating material, resulting in a thin, uniform layer. This technique is highly valued for providing excellent corrosion resistance without the worry or risk of hydrogen embrittlement, which can be a concern with some electroplating processes.
