Automotive is one of the largest markets for Surface Finishing Processes. Automotive components undergo the harshest outdoor conditions and therefore good surface finishing is of the utmost importance. Corrosion is one of its biggest enemies and most of the surface finishing process done on automotive components are to prevent it from corrosion.

Electroplating of automotive components helps to prevent the components from rust and increases their wear resistance.

Growel manufactures a series of Electroplating plants for a range of electroplating processes to suit the Automotive Industry.

Zinc and Zinc Alloy plating :

Zinc & Zinc alloy plating provides excellent corrosion protection and a good aesthetic finish. It is usually followed by Passivation which helps to enhance the corrosion resistance.

Nickel Chrome plating:

Nickel Chrome plating leaves an aesthetically pleasing finish. The automotive industries use this process to achieve a shiny and glossy appearance on their components. It forms a hard outer layer which improves the corrosion and wear resistance of the component.

Plating on plastic:

Plating on plastic is another major application in the Automotive Industry. Components such as grills, bumpers, door handles, chrome accents etc. are generally made of plastic. Electroplating on a non-metallic surface such as plastic is possible, and it greatly improves its appearance. The process is tough to get right and requires in-depth process knowledge. Growel manufactures and supplies plating on plastic plants to suit various components.


Aluminium due to its lightweight and durability is widely used in the automotive sector. Wheels, radiators, housings, transmission parts are few examples of aluminium components. Anodizing aluminium increases its durability and provides a pleasing aesthetic finish. Growel has supplied numerous anodizing plants to cater to a range of Aluminium components.


Phosphating is long-employed in the Automotive industry. It has been in use for many years and has proved beneficial as a metal pre-treatment before painting. Phosphating provides outstanding corrosion protection and effective paint adhesion. Phosphating also improves frictional properties of sliding components. Manganese Phosphating is typically applied on gears and engine components which are prone to sliding. Zinc Phosphating is typically applied to provide resistance from corrosion.

Zinc Flake Coating:

Zinc flake Coating is a protective coating applied to automotive components such as fasteners, springs, brake callipers, transmission parts.

Growel has supplied surface finishing plants for a range of automotive components. Few of which are mentioned below:

  • Rims
  • Piston Rings
  • Gears
  • Handlebars
