[Troubleshooting] We will explain the causes of uneven gloss in plating and points for improvement.
One of the appearance troubles of plating is "gloss unevenness." Have you ever experienced that the finish of the plating is not uniform, that the gloss differs between the front and back of the product, or that there are differences in gloss between lots? Various factors influence the finish of plating, but what kind of differences in conditions can cause gloss unevenness? Factors that affect the gloss of plating include: A) Differences in the surface roughness of the product substrate B) Residual oil, dirt, or scale on the product C) Differences in plating film thickness D) Management of the plating solution (such as pH and gloss agent addition) E) Etching during pre-treatment of plating Possible countermeasures for each factor include: a) Uniforming surface roughness through polishing or blasting b) Reviewing pre-treatment conditions and barrel polishing or blasting c) Reviewing plating conditions, racking methods, and jigs d) Regular liquid analysis and appropriate replenishment and renewal e) Reviewing pre-treatment conditions (such as pickling) Since the treatment processes and conditions vary among plating companies, it can be difficult to respond even if the cause is understood. Our company can adjust treatment conditions according to the state of the product. Please feel free to consult with us.
