Surface treatment is an integral part of production in the Hardware and Fastener Industry. Hardware and Fasteners are required virtually by every industry, and they are used in thousands of applications. The quality and finish of these products depends on their application, which means, several surface finishing processes can be carried out to suit the required application. However, all hardware and fastener components need to have a good corrosion and wear resistance.
Electroplating of Hardware and Fastener components helps to prevent the components from corrosion and increases their wear resistance.
Growel manufactures a series of Electroplating plants for a range of electroplating processes to suit the Hardware and Fastener Industry.
Zinc is the most economic and ideal fastener and hardware plating material for most outdoor and industrial applications. It provides excellent corrosion protection and a good aesthetic finish. It is usually followed by Passivation which helps to enhance the corrosion resistance.
Nickel helps with the corrosion resistance; its thickness is based on the application of the component. Nickel usually gives and white finish which is then followed by chrome plating which has a translucent finish which is hard and scratch resistant.
Zinc Flake Coating is also known as GEOMET coating is a water or solvent based corrosion preventive coating technology. It is widely used to coat hardware and fasteners to be employed in the automotive application. It generally has a coating thickness of 6-15 microns and resistance to salt spray test in the range of 700-1500 hours. The components also develop a high coefficient of friction.
Major benefits of Phosphating on hardware and fasteners is to provide corrosion resistance and good adhesion to paint. Phosphating is employed on threads of fasteners and coated with oil to increase resistance to wear between sliding surfaces. Manganese Phosphating is typically applied on fasteners and hardware components which are prone to sliding. Zinc Phosphating is typically applied to provide resistance from corrosion.
Anodizing helps provide a protective layer which prevents damage from rust and corrosion. Anodized components can even be dyed to impart a attractive colour. Normally, Aluminium bolts and hardware components are employed for Anodizing.
Growel has supplied surface finishing plants for a range of Fasteners and Hardware components. Few of which are mentioned below:
Surface Finishing provides several benefits for Fastener and Hardware components:
To achieve the above-mentioned benefits various processes are employed on the components:
