Sealing

Sealing in electroplating is a process that is applied after the plating process to further improve the quality and durability of the electroplated coating. After the workpiece has gone through the electroplating process and has been coated with a layer of metal such as nickel, copper or chrome, an additional sealing layer can be applied.

This sealing layer, which often consists of special paints or coatings, serves to seal the porous surface of the electroplated coating. This prevents moisture, air or other harmful substances from penetrating the coating and causing corrosion or other forms of damage.

Sealing in electroplating can be done in various ways, depending on the specific requirements of the application and the properties of the coating. This can include the application of paint by dipping, spraying or brushing, with the coating then being polymerized by heat treatment or curing to ensure a permanent seal.

Electroplating sealing offers a number of benefits, including improved corrosion resistance, increased durability of the coating, improved aesthetic appearance and easier cleaning and maintenance of the coated parts. By applying sealing after the electroplating process, high quality and durable coatings can be achieved that meet the requirements of a wide range of applications.
