Hole metallization

Hole metallization is a surface technology process used to create metallic coatings in drilled holes or other recessed areas of workpieces. This process makes it possible to coat the inner walls of drill holes with an even and durable metal layer, which offers various advantages.

In drill hole metallization, the areas to be coated are first prepared to ensure good adhesion of the metal layer. The workpiece is then immersed in an electroplating bath containing the metal ions from which the coating is formed. By applying an electrical voltage, the metal ions are deposited on the surface of the workpiece, forming a uniform metal layer that also adheres to the drill holes.

Drill hole metallization is used in various industrial sectors, particularly in the electronics and automotive industries. For example, it is used in the manufacture of printed circuit boards to reinforce and protect the electrical connections in the drill holes. In the automotive industry, it can be used in the manufacture of engine components to improve the wear resistance and durability of the parts. Overall, hole metallization is an important process in surface engineering that helps to improve the performance, durability and functionality of parts with recessed holes.
