Electroplating is a metal treatment process that consists of depositing another metal on a metal surface through chemical or electrolytic reduction. This coating is usually done to protect the primary metal part from corrosion, and to achieve an aesthetic/decorative finish. Depending on the metal that is coated on the object, the process receives special names – gilding (gold), chrome plating (chromium), silver, nickel plating and others. Through electroplating, the treated metal generates an improvement in its characteristics, obtaining hardness and duration. Silver is a metal widely used in electrical contact parts due to its characteristic of being the best electrical conductor among all metals. In silver plating in UAE, the metal parts receive a bath layer as requested by the customer.
Silver electroplating – benefits
The benefits of silver plating in UAE in technical applications and decorations are many. The most important being the increase in electrical conductivity to acquire a more pleasing aesthetic finish. By obtaining greater electrical conductivity after electroplating silver plating, the part will have greater efficiency in use in electronic applications, enhancing its usefulness. This efficiency is extremely important for the electro technical industry, which performs silver plating electroplating on several different types of parts.
In domestic or decorative use, the use of silver-plated metal coating in UAE is preferred, given the increased durability it provides to the piece in question, besides making it more attractive with the characteristic tone of silver. The silver bath is used in the production of jewellery, which have a more affordable cost than the pieces made in pure silver. There are four different types of processes for silver plating electroplating – the rotary process (in large quantities of pieces in bulk), the static bath or hook (for specific pieces with complex geometry), the spool type (indicated for chains) and the continuous process (used in wires and tapes).
How is the silver-plating process constituted?
Silver plating in UAE is performed through electrolysis. Electroplating prevents contact of the part’s metal with air and moisture. Electroplating is also used in items belonging to the metallurgical and civil construction industries. In these cases, the process includes the use of metals such as cadmium, nickel, copper, tin and zinc. The companies that manufacture jewellery usually use gold, silver, rhodium and palladium. The procedure for electroplating is divided into three stages –
Pre-treatment: In the process of metal coating Dubai, the surface of the object is prepared so that it is adherent. Brushing, sanding, polishing, pickling and blasting to remove burrs, grooves, paints, greases and rust are some of the activities carried out at this stage
Treatment: The piece is subjected to one or more metal baths to acquire a thin metallic bed.
Post-treatment: At this last moment, the piece undergoes a washing process with hot or cold water, drying in a centrifuge, oven or air jets, besides an oil bath for packaging, protection and painting or varnishing.
Metal silvering procedure
To carry out the silver plating in UAE process, the metal to be galvanized is introduced into the barrels with special loading machinery. Before carrying out the silvering process, the material is thoroughly degreased in different chemical tanks. Various cleaning steps of the metal to be galvanized are performed.
Through the electroplating in Dubai process, the silver anodes release silver which is deposited on the material to be silvered. Silver is a relatively noble metal. It is why the immersion of a less noble metal in its solution can cause cementation phenomena that are deleterious for the adhesion of the next layer. To try to minimize this effect it is necessary to carry out a pre- silvering process.
The thick silver plating is performed for functional purposes. The characteristics of the thick silver plating vary according to the customer’s requests. Based on the chemical component of the silver bath – which is analyzed several times during the day, to ensure the maximum yield of the silver deposit – the thickness requested by the customer is guaranteed through the thickness certificate. The characteristics of electrolytic silvering are good resistance to corrosion and do not affect the conductivity of the metal to be galvanized.

Accessory silver plating
The electrolytic silvering on metal can be performed for aesthetic purposes, on the most varied materials, such as handles, buttons, hinges, knobs. Many objects, thanks to the galvanic treatment, can be coated with silver. The electrolytic galvanic treatment of silvering on a metal surface is performed for aesthetic and decorative purposes. The decorative galvanic silvering is used to obtain purely aesthetic finishes.
In order to obtain a galvanic coating of shiny silver, the material to be coated is immersed in a silver bath and with the addition of rinse aids and surfactants and a series of chemical components of the bath, a shiny silvering is achieved. Thanks to the great experience gained over the years, metal coating companies in Sharjah manage to use many types of shades during its galvanic coatings, to satisfy the various market demands. The finishes developed are increasingly original and refined.
