Metallic coatings provide a layer that changes the surface properties of the workpiece to those of the metal being applied. The workpiece becomes a composite material exhibiting properties generally not achievable by either material if used alone. The coatings provide a durable, corrosion resistant layer, and the core material provides the load bearing capability. The deposition of metal coatings, such as chromium, nickel, copper, and cadmium, is usually achieved by wet chemical processes that have inherent pollution control problems.
Alternative metal deposition methods have replaced some of the wet processes and may play a greater role in metal coating in the future. Metallic coatings are deposited by electroplating, electroless plating, spraying, hot dipping, chemical vapor deposition and ion vapor deposition. Some important coatings are cadmium, chromium, nickel, aluminium and zinc.
Additional improved services include wet paint finishing, using a 12 meter long humidity and temperature controlled spray booth, our paint sprayers are able to produce the best results to the highest standards on any component surface.
The shot peening process is the most cost effective and practical method of inducing surface residual compressive stresses.
ALUMINIUM OXIDE BLASTING
Aluminium oxide blasting is a form of abrasive blasting that involves propelling abrasive media using compressed air onto the surface of metal components.
GLASS BEAD BLASTING
Glass bead blasting is a gentler process that will enhance the finish of machines parts and produce a bright, non-glare subtle finish.

Chemical Blacking helps to preserve the metal from corrosion which gives a decorative black finish on most ferrous surfaces. This is quite critical on screw thread and bearings.
Vapor blasting uses water with media which is recycled around the machine. The water buffers the media when it hits the component giving a smooth finish, especially on stainless steel and aluminium, without damaging the metal.
Plating and surface treatment processes are typically batch operations, in which metal objects are dipped into and then removed from baths containing various reagents to achieve the desired surface condition. The processes involve moving the object being coated through a series of baths designed to produce the desired end product. These processes can be manual or highly automated operations, depending on the level of sophistication and modernisation of the facility and the application.
