Electroplating Market: Types of Electroplating, Applications of Electroplating, Supply Market Overview

Sep 4, 2018

Electroplating is the process of using hydrolysis for plating one metal onto another. The process of electroplating is extensively used to modify the surface properties such as rust resistance and abrasion of objects. This process involves the use of an electric current, which is passed through the electrolyte (solution) containing two terminals called as electrodes. These electrodes are connected through a circuit with the power supply or battery. On passing an electric current through the circuit, the electrolyte in the solution splits up and some atoms from the metal are deposited on the top of one of the electrodes in the form of a thin layer. Metals like copper, gold, nickel, zinc, silver, cadmium, chromium, and tin are used in the electroplating process. This process is considered to be an important aspect in the production of electrical and electronic appliances, as it provides a coating on the surface of the metal of components used in these appliances. This helps in improving corrosion resistance, improves the conductivity of electricity, and enhances the solderability of the substrates. There are various applications of electroplating, but before deep diving into that, let’s see its different types: (Source: SpendEdge procurement report on electroplating category)

Types of Electroplating 

Mass plating

Mass plating is one of the types of electroplating that is used to plate a large volume of components in little to no time. To perform mass plating, a barrel is loaded with parts and then placed inside a container, which is filled with the coating material. Following this, the barrel is rotated to ensure that all the components inside the barrel are evenly coated for protection from corrosion. Mass plating is one of the most common types of electroplating and is one of the processes with the maximum applications. However, the mass plating process also brings parts in contact with one another, which can create an adverse effect on the coatings. So, another electroplating process can be used for components that require a high degree of aesthetic appeal.

DemoFollowing are the common examples of parts or components that undergo these types of electroplating:

  • Bolts
  • Nuts
  • Screws
  • Washers
  • Pins
  • Electrical Connectors

Rack plating

Rack plating is used to electroplate large, complex, and brittle parts that are tough to plate using other methods. In this process, parts are mounted to a “rack” and then immersed in a plating solution. This method provides uniform distribution of coating since the rack holds different parts that are plated at the same time. These types of electroplating processes are common in aluminum and zinc, and chrome and nickel are commonly used as plating solutions. Shape, size, and quantity of the parts must be considered before settling on this process.

Continuous plating

In continuous plating items like tubes, wires, and strips are plated by running them continuously through a plating solution, one after the other. This process involves the even distribution of the coating material, such as zinc, aluminum, or tin, onto a metal like steel. It helps to enhance the corrosion resistance, appearance, wear, or other properties of a metal. Continuous plating provides even distribution of the coating and the electric current.

Applications of Electroplating 

#1. Forms a protective layer– One of the most important applications of electroplating is that it helps the plated parts to last longer and less frequent replacements. It also helps the metal to hold up the extreme conditions.

#2. Improves appearance– This is one of the most useful applications of electroplating that helps make products more appealing aesthetically. Jewelers can sell products that look like pure gold or other precious metals at a much lower price.

#3. Minimizes friction– This is one of the valuable applications of electroplating. It helps to improve performance and reduces friction to a large extent.

#4. Prevents whiskers formation – This is one of the prominent applications of electroplating since it reduces the damage caused by shorts and arcing in electrical components and parts caused by whiskers.

#5. Improves durability – Plating helps the metal surfaces to become less susceptible to damage when dropped or struck and, thus, increases the lifespan of the metal.
