Zinc plating is the most common and economical type of plating. Zinc plating is a soft, protective by nature, decorative, ductile, marginally solderable and also serves as an effective undercoat for paints. It is sacrificial coating, so that part does not corrode.
In the process of Nickel Electroplating, coat of nickel metal is deposited over another metal for inducing certain superior properties. The process done through an electrolytic solution. This electroplating process is widely used in the electronics and chemical industries. Some of the features of nickel coating that is deposited on the metal surface are as follows :
Chromium layers of high thickness used for engineering purposes is termed as Chrome Plating. The properties of hard chrome plating which render it of most value for engineering purpose are its intrinsic hardness which is between 60 to 65 HRC and its low co-efficient of friction and high wear resistance.
Chrome Plating is an effective treatment for a variety of metals. Hardness of deposit (1100-1250 H.V.) giving greater wear resistance. Whilst micro-cracking (>300cm-1) improves corrosion resistance. Coatings can be applied to customer specification and requirements. For heavier deposits i.e. approx. 0.5mm, it is advisable, if possible, to capture the ends of the component being plated to reduce the chance of "chipping" of edge build up.
We are doing various types of silver plating. Major one is to enhance electrical contact. Silver plating is widely used on electrical and electronic components such as switch gear and panel boards because of its superior conductivity and longevity compared to copper and brass.
Tin plating is a soft white, non-toxic, solderable, soft deposit, useful for its resistance to corrosion and tarnish. Tin, this can readily be polished, scratch brushed or flow-melted to give a bright finish. These qualities make it a prevalent finish in the food processing and shipping industries. Electroplated Tin, both dull and bright is widely used as a protective coating on ferrous and non-ferrous metals. Tin plating work is also widely used in the electronics industry, due to its ability to preserve low contact-resistance on connectors, semi-conductors, and components. Tin is also very soft and malleable, so it can be transformed without cracking, we do all type of tin plating jobs.
Cadmium plating involves placing a coat (or plate) consisting of a thin layer of material in this case, cadmium over an object. In general, plating is used for protection against corrosion and, overall, making an object last longer. Cadmium plating offers several advantages: superior resistance to corrosion; anti-galling, anti-fungal and anti-static qualities; solderability and ductility. Cadmium plating is mostly used in aerospace and military applications, but it's useful for any parts that will be used in harsh environments.
Copper is a soft metal with excellent electrical and thermal conductivity and provides good solderability. Copper is plated for use in industrial and decorative applications. It is also used to mask off areas of steel components in the case hardening process. Best under coat for better adhesion and brightness on case hardened steel, nitrided components, alloy steels, cast iron etc.
Gold is unique with its yellow color. Also, gold is a precious metal, which means that it will not oxidize in air, so its electrical conductivity stays uniform over long periods of time. It is ideally suited for gold electroplating applications. Gold plating offers good corrosion resistance, good solderability, and when alloyed with cobalt, it has very good wear resistance. Gold is commonly used in electrical switch contacts, connector pins and barrels, and other applications where intermittent electrical contact occurs.
Zinc Nickel is a high performance coating that provides exceptional corrosion protection in harsh environments.Zinc Nickel applications for the automotive , electronics, aerospace and defence industries. Zinc Nickel is used to plate fasteners for use in high corrosion areas. In electronics used for connectors. Zn-Ni delivers corrosion resistance and high electrical connectivity.
Paint is any pigmented liquid or mastic composition that, after application to a substrate in a thin layer, converts to a solid film. It is mostly used to protect and colour to objects. Paint can be made in many shades.
Powder coating is an advanced method of applying a decorative and protective finish to any type of metal.Powder coated surfaces are more resistant to chipping, scratching, fading and wearing than other finishes. Colour selections is virtually unlimited.
