Tumbling Service (Manufacturing) is a specialized industry that involves the process of polishing and finishing metal parts through the use of tumbling machines. This industry is a subdivision of the Electroplating, Plating, Polishing, Anodizing, and Coloring (Manufacturing) industry and is focused on providing high-quality finishing services to a range of clients. The process of tumbling involves placing metal parts in a rotating drum or barrel along with abrasive materials such as sand, ceramic chips, or steel balls. The parts are then tumbled for a set amount of time, which can range from a few minutes to several hours, depending on the desired finish. This process helps to remove any burrs, sharp edges, or other imperfections from the surface of the metal parts, resulting in a smooth and polished finish.
