We offer high grade zinc plating to our clients. For this purpose, we use environment friendly non cyanide zinc process to ensure high quality plating. We ensure different colors such as blue, yellow, and black as per requirements of our clients. Zinc coatings prevent oxidation of the protected metal by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust (in contrast to iron oxide) Does not cause a breakdown of the substrate?s surface integrity as it is formed. Indeed the zinc oxide, if undisturbed, can act as a barrier to further oxidation, in a way similar to the protection afforded to aluminum and stainless steels by their oxide layers.
Zinc Plating (Trivalent Yellow Passivation)
No hexavalent chromium higher salt spray up to 200 hrs(nss 5%) white rustiridescent yellow color minimum attack on zinc plating eco friendly quality meet out intentional standards passivation film has high hardness, less ware and tare thickness up to 400-500 nm suitable for automobile and export and export items.
Acid Zinc Plating
Acid zinc plating systems have several advantages over alkaline cyanide and alkaline non-cyanide zinc plating systems: Less waste treatment, since no cyanide treatment is required and no chelating agents are used; Deposits with outstanding brightness that rival nickel chromium in their luster; High cathode efficiencies, 90-95%, at normal operating current densities;Plates difficult substrates such as castings and carbo nitrated pieces, which can be plated directly without any special pretreatment.
Zinc Cobalt Process
High corrosion resistance sacrificial coating. Compatibility with existing Zinc-Chloride rack and barrel. Easy to operate and control. Acceptance of wide range of passivation color including silver free black. Cost is only 15-20% more than Zinc. (0.4-0.8% deposit of Cobalt) Easy waste treatment. No complex procedures involved. Do not require special chromate only adjustment is required.
The tin plating is used extensively to protect both ferrous and non-ferrous surfaces. Tin is a useful metal for food processing industry. Since it is non-toxic, ductile and corrosion resistant. The excellent ductility of tin allows a tin coated base metal sheet to be formed into a variety of shapes without damage to the surface tin layer. It provides sacrificial protection for copper, nickel and other non-ferrous metals, but for steel.Tin is also widely used in the electronics industry because of its ability to protect the base metal from oxidation thus preserving its solider ability. In electronic applications, lead may be added to prevent the growth of metallic ?whiskers? in compression stressed deposits, which would otherwise cause electrical short.
Electro Less Plating (Nickel)
Electro less plating, also known as chemical or auto-catalytic plating, is a non-galvanic type of plating method that involves several simultaneous reactions in an aqueous solution, which occur without the use of external electrical power. The reaction is accomplished when hydrogen is released by a reducing agent, normally sodium hypophosphite; gets oxidized thus producing a negative charge on the surface of the part. The most common electro less plating method is electro less nickel plating.
Hot Dip Galvanizing Process
A hot alkali solution is used to remove organic contaminants paint mark, grease and oil free from the surface. This water rinse removes most of the alkali solution from the surface prior to acid cleaning. Rust and mill scale are remove from the surface. This water rinse removes most of the hydrochloric acid solution from the surface prior to the application of the fluxing agent. Fluxing is the final surface preparation step in the galvanizing process, item to be galvanized are immersed in a solution of zinc ammonium chloride this application promotes bonding of the zinc to the surface. Steel items are immersed in a zinc bath and heated 400 to 600 degrees fahrenheit; this forms a metallurgical bond between the zinc coating and underlying steel. After the galvanizing step, the steel items are air cooled until they can be cleaned and inspected prior to being ready for shipment.
