Industrial hard chrome plating is a process used to improve the surface properties of metals and other materials. The process involves electroplating a thin layer of chromium onto the surface of the material, which can increase resistance to wear and corrosion, as well as improve appearance. Hard style chrome plating has many industrial applications, including automotive components such as brake drums, pistons, crankshafts and suspension parts; tools used in manufacturing such as drill bits, saw blades and dies; and medical instruments like joint replacements and prosthetics.

The Part is Immersed in An Acid Bath

Industrial hard chrome plating requires precision equipment, highly skilled technicians and specialized chemicals. The industrial plating process begins with pre-cleaning of all surfaces that will be treated. A suitable chemical solution is used to remove any dirt, oil and other contaminants from the surface. After pre-cleaning, the part is immersed in an acid bath that etches the surface, creating a rougher texture for better adhesion of the plating material. 

Requiring Only a Few Microns

The next step involves electroplating, which is done by submerging the part in an electrolyte solution containing chromium ions. An electrical current is passed through this solution to deposit a thin layer of chromium on the part's surface. The thickness of this layer can vary depending on the application, with some parts requiring only a few microns while others may require up to five or six times as much chrome. It is important that the correct amount of chrome is applied to ensure that the part can withstand its intended use.

Brightening or Polishing

The electroplating process takes place in a temperature-controlled plating tank. The part may also be subjected to additional treatments such as brightening or polishing, depending on the application and desired finish. Finally, post-treatments are performed to remove any excess chrome and prepare the surface for further assembly or coating processes.

Professionals With the Necessary Expertise
