What Every Engineer Needs to Consider Before Electroplating

Within the last few decades, metal finishing has transformed itself, from an empirical process to an important technique based on scientific principles. Electroplating has become an important technology in many industries because when the metal coating is applied to the surface of a part or component using an electric current, it can improve the performance and durability of metal parts and can produce high quality finished parts This metal finishing type is used in various industries including aerospace, automotive, military, medical, RF microwave, aerospace, electronics, and battery manufacturing.

With so many types and methods of electroplating available, you have to determine the right procedure for the size and volume parts you have. Are you looking for an electroplating services company? There are many trusted companies out there that offer electroplating and other metal finishing services to industries of all types.

To get the best results with your electroplating, engineers must first consider some important factors:

Intended Use of Parts

Your ultimate performance goal will determine the correct type of electroplating for the part, because different types of metal plating offer multiple benefits. You must also consider the environment in which the final product will be used. If your parts are exposed to excessive wear or a corrosive environment, these factors will also affect the type of coating you choose.

Drainage Holes

When the part is immersed in the plating solution, deep cavities or holes in the part may cause air retention. This may prevent the coating from adhering properly or form areas of thinner plating. Holes may also trap chemicals or solutions during the cleaning process, which has the same detrimental effect on the final result. In order to prevent air or solution from being trapped, drainage holes can be added to the design of a part to allow air to escape so that the electroplating solution can enter and the coating can be properly distributed.

Quality of Base Material

Although metal coatings can improve the appearance of parts or products, but it is not meant to cover scratches or marks on the substrate. Mechanical finishing must be completed before electroplating. In addition, if the welding of the parts is not complete, it may cause chemicals or air to be trapped. Before galvanizing, make sure that the parts have been properly welded or weld flux is removed.

Geometry

The shape and configuration of the parts will affect the uniformity of the metal coating distribution. The current density in different areas will be higher or lower, resulting in thicker or thinner plating. The corners and edges will have a higher current density, and therefore will have a higher plating thickness compared to gaps and cavities. Keep this in mind when designing parts and planning for final coating thickness.

Tolerances

Since electroplating involves depositing a layer of metal on the surface of a component or part, make sure to account for dimensional changes by providing tolerances. Consider the entire assembly to determine the appropriate plating thickness.

Conclusion:

When choosing an electroplating services company to work with, be sure to consider the type of coating you want and the electroplating method your parts required. Find a company that can provide you the proper services and completely protect your parts from damage during the process.
