MANY SURFACE PREPARATION OPTIONS
From a dazzling mirror-like appearance to a totally nonreflective texture, specially prepared surface finishes add both functionality and attractiveness to many products. A matte finish is normally used on the interior of cameras, microscopes and other optical products. The front panels of many pieces of electronic equipment have a brushed or satin finish, while a number of consumer products have enhanced appeal due to their highly polished appearance. Medical and dental tools for surgery are another application where a smooth polished surface is required. More than one texture can often be utilized on a single component.
POLISHING – Both manual and automated polishing techniques are often utilized before anodizing to smooth irregularities and increase surface reflectivity. Polishing provides a highly decorative and mechanically smooth surface. A highly polished and anodized finish adds eye appeal and value to any component.
GRAINING – A grained, brushed or satin surface, plus anodizing, yields a high-tech satin look. Grained or blasted finishes are a practical method to remove surface irregularities while imparting a quality textured finish prior to applying a protective coating.
BLASTING – A variety of abrasive substances are used to break up or remove surface irregularities. It is also useful for light deburring. This technique creates nonreflective finish, within a range of controlled textures, which may then be anodized.
These sprockets were brush-finished for deburring, and then the resulting grained finish was anodized and dyed. A wide range of color choices is available.
