The most common cleaning methods in the small metal parts and tooling industry include spray, immersion, and ultrasonic cleaning, using water or solvents. These treatments are chosen based on the complexity of the parts and the type of contaminants, such as cutting oils, abrasive pastes, metal powders, and machining residues. These processes prepare the surfaces for subsequent treatments such as tumbling, sandblasting, phosphating, and passivation, which improve corrosion resistance and the adhesion of any coatings. In tool manufacturing, treatments such as nitriding and PVD coatings are often used to increase surface hardness and durability. The effectiveness of these processes is crucial to meeting the technical standards required by high-precision industries.
