Welcome to BAJAJ ELECTROPLATERS
Gold Electroplating
One of the most attractive and precious decorative metal is Gold. This metal is mainly used for Jewelry and decorative electronic Items. This process involves deposition of a thin layer of gold on the surface of some other metal. Apart from gold the other metals mostly used are Silver or copper. Gold imparts excellent corrosion resistance properties when deposited in surface of copper. The gold metal is widely used in the electronic industry for plating of circuit boards and electrical connectors.
Copper Electroplating
Besides Gold the other important and mostly used metal is Copper which is used for imparting the properties of copper on other metal surfaces. The process is carried out in a electrolytic solution with a copper strip acting as cathode and the metal to be electroplated acting as anode. Copper metals are slowly deposited on the surface of the other metal and hence properties of copper metal. These are also transferred to that metal surface.

Silver Electroplating
We offer cost effective Silver Electroplating services to our esteemed clients. Our silver electroplating services are widely used for jewelry making and in electronic & chemical industries. Use of electric current for reducing the cautions of a material from the electrolytic solution and coating the same as a thin layer on the desired material is the process of electroplating.

Silver plating on copper and copper alloys should have a nickel undercoat. Copper and copper alloy material on which a nickel undercoat is not used, and other base metals where a copper undercoat is employed, should not be used for continuous service at a temperature in excess of 300 degrees F (149 degrees C). Adhesion of the silver plating is adversely affected because of the formation of a weak silver and copper intermetallic layer.
Brass Electroplating
Apart from gold, copper & silver another important metal used for electroplating is brass. brass electroplating is used for the creation of bass sculptures. brass electro formation refers to a metal forming process which is formed in thin parts through the electroplating process & is produced as a result of plating a metal skin onto a base form. This is known as mandrel. Brass electroforming process which produces plating, much thicker and can sustain itself even if the mandrel is removed.
- It plates twice as fast as any other cyanide brass process]
- It is a single additive process with excellent throwing power that produces a lustrous, highly desirable yellow-green, 70/30 brass color
- It is a low temperature process operating at 105° F and can be used in both rack and barrel operations
- The copper and zinc plate together in a uniform alloy composition over a wider current density and temperature range, thereby helping to reduce rejects due to poor color, non-uniformity and poorly oxidized finishes
- The E-Brite B-150 utilizes electrosolv as an anode corroder which retards the growth of carbonates, plus in barrel brass lines utilizing electrosolv will eliminate the need for addition of copper and zinc cyanide when using 70/30 brass anodes
- An alkaline, chromate-based passivating solution for brass, bronze, copper and silver
- It is used cathodically after plating to prevent spotting and bleed-out and preserves the original color of plated surfaces
- It provides excellent short term protection for parts in processing with resistance to 100 hour salt spray and 500 hours of 100% humidity without a lacquer topcoat
- It is the preferred agent for increased corrosion resistance for plated objects top-coated with a clear acrylic or epoxy lacquer and also for clear powder coatings
- The use of BPA will double and even quadruple the life of a clear top-coat
- It also works equally as well on solid wrought brass alloys and copper
Nickel Electroplating
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:
- Decorative appearance
- Corrosion protection
- Wear resistance
- Low coefficient of friction.
- Ferromagnetism
- Controllable internal mechanical stresses
Satin Nickel Plating Services
We provide Satin Nickel Plating Services, which are ideal for steel, copper, brass, zinc die-castings and powdered metal. Our experts make use of bright nickel solution is used to provide a decorative finish and it acts as an excellent barrier coating to minimize metal migration. Satin nickel plating is used where improved ductility and solderability is required.
Tin Electroplating
- Tin offers excellent solderability
- Tin can cover a wide range of shapes and components
- Tin provides corrosion resistance
Hard Chrome Electroplating
Hard Chrome Electroplating is produced by Electro-deposition in a solution of chromic acid. It is also known as industrial, functional or engineering chromium plating and is very different from decorative chromium plating.
- Corrosion resistant
- Surface hardness (55 to 62 Hrc) / ( 850 to 1050 Hv )
- Abrasion resistance

Electroless Nickle
The nickle electroplating process can be used to coat nuts, bolts, washers and automotive parts, such as interior components and gas filters. It also provides an effective undercoat for paints, when high corrosion performance is required.

- Bright finish
- Uniform coating
- Functional engine components,
- Pistons,
- Cylinders,
- Pump spares,
- Valve components,
- Moulds and Dies,
- Most complicated designed machinery parts.
Zinc Electroplating
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. Zinc plating is available in clear, yellow, black and olive green. Trivalent chromate passivations are available if requested .
Benefits of Zinc Plating
- Ultra bright zinc deposit. Approaching that of chloride zinc.
- Excellent ductility & adhesion. Maintains ductility even with thicknesses in excess of one mil.
- A low stress deposit.
- Superior zinc deposit plate distribution.
- Consistent distribution.
- Excellent chromate conversion coating receptivity.
- Zinc deposit appearance is comparable to cyanide or chloride zinc.
- Operates within wide range of bath chemistry.
- Temperature tolerance up to 120oF, which reduces cooling costs.
- Excellent brightener stability and brightener life of 30,000 amp hours.
- Suitable for either rack or barrel plating.
- Simple waste treatment procedure.
- A reliable, easy to maintain process.
- It contains no complexers or chelating agents.
- Surface of the metal is cleaned in alkaline detergent type solutions, and it is treated with acid, in order to remove any rust or surface scales. Cleanliness is essential for successful zinc electroplating, as the molecular layers of oil or rust can prevent adhesion of the coating.
- Next, the zinc is deposited on the metal by immersing it in a chemical bath containing dissolved zinc. A DC current is applied, which results in zinc being deposited on the cathode. Alkaline zinc baths are used by the finished products, to produce a more consistent zinc thickness, especially in recesses.
- Hence an increased protection from corrosion is provided, as the corrosion of the deposited zinc is reduced. The zinc coating can increase the time required for the formation of white rust, by ten times. Finished Products also apply sealers, which are now commonly being specified by the automotive industry, further increasing corrosion protection.
It is very difficult to obtain a uniform thickness of coating, with electroplating technique. The thickness of the coating is very much dependent on the geometry of the object being plated, and it is preferentially on the external corners and protrusions of the metal body, hence not much of it is deposited on internal corners and recesses. Zinc electroplating process is used to make a clean, smooth and corrosion resistant surface. It also makes an excellent undercoat for powder coating or paint and can leave recesses on complex shaped components without sufficient zinc coating, in order to provide corrosion protection.
