The mechanical plating process starts with the preparation of the pieces. They are thoroughly cleaned to remove any oils, corrosion, or other impurities that may interfere with adhesion. Following cleaning, the pieces are placed in a spinning barrel with metallic powder (often zinc), impact media (such as glass beads), and a proprietary chemical solution. As the barrel rotates, mechanical action forces the metal powder to adhere to the surfaces of the pieces via cold welding. The end product is a homogeneous, dense coating that provides exceptional corrosion protection while retaining the part's mechanical qualities.
One of the primary benefits of mechanical plating is its ability to coat complicated geometries and threaded components without causing buildup or uneven coverage. Because the method does not use high heat or electrical currents, it removes the risk of hydrogen embrittlement, making it perfect for critical applications in the automotive, aerospace, and construction industries. Furthermore, mechanical plating is environmentally benign because it generates less waste and does not employ harsh chemicals like cyanide or chromium, which are typically used in electroplating.
Mechanical plating is also less expensive. The process is very efficient, with shorter cycle durations than conventional coating technologies, resulting in lower labor and energy expenses. It also enables exact control over coating thickness, resulting in consistent quality across huge batches of parts. Furthermore, mechanical plating can be used on a wide range of metals, including steel, iron, and copper alloys, making it a versatile solution for a variety of industrial applications.
Mechanical plating is widely used for fasteners, bolts, nails, springs, and other small metal components that require long-lasting corrosion protection. The zinc coatings created with this procedure give good sacrificial protection, which means the coating will erode before the base metal, extending the part's lifespan. Following mechanical plating, further treatments like chromate passivation or sealers can be used to increase corrosion resistance even further.
