Selective Hard Anodizing

Erie Protective Coatings has over the past few years been involved in special masking of components requiring selective anodizing. Such an application is seen in close tolerance mating components, parts where threads need to be protected to prevent thread interference or in components requiring certain areas of electrical continuity. The masking can be as simple as inserting of special plugs into the required areas or it could involve extensive painting of the area requiring no anodizing. After the anodizing process is completed the masking is carefully removed.
