Electroplating is a popular metal finishing and improving process used in a wide range of industries for various applications. Despite the popularity of electroplating, however, very few outside of the industry are familiar with the process, what it is and how it works. If you''re considering using electroplating in your next manufacturing process, you need …

Electroplating is the process of plating one metal onto another by hydrolysis, most commonly for decorative purposes or to prevent corrosion of a metal. There are also specific types of electroplating such as copper plating, silver plating, and chromium plating. Electroplating allows manufacturers to use inexpensive metals such as steel or zinc ...

Obviously, the thicker the plating the longer it will last and the more protection it will give, but even the thickest plating is much thinner than you might expect. The typical thickness of plated metal varies from about 0.5 microns (0.5 millionths of a meter or 0.0005 millimeters) up to about 20 microns (20 millionths of a meter or 0.02 …

Silver thickness ranges 1.875 to 5.0 /~m (0.000075-0.000200 in.), with deposition times between 1 and 4 sec. The small areas to be plated demand the use of insoluble anodes. Platinized-titanium mesh and platinum wire are examples of anode materials in common use. Traditional cyanide silver electrolytes suffer rapid degradation …

With CHP, Helsinki saves so much energy compared with separate property-specific heating produced by condensing electricity that it would heat up to 500,000 detached homes each year. The majority of homes in Helsinki are heated with district heat throughout the year. About 90% of district heat in Helsinki is produced in CHP plants.

We can handle single items up to combined maximum dimensions of 20in (50cm) long, 18in (45cm) wide and 16in (40cm) deep. We are proud to retain to this day a traditional silver plating process where every item is hand-wired. Our manual process also achieves a thicker finish, ultimately improving the end quality and depth of the silver finish.

Firstly, electroplating a metal using copper allows it to be protected against nitriding and carburising. The coating formed as a result of copper plating protects the surface against the negative effects of heat, moisture and corrosion, as well as adverse weather conditions. Secondly, the electroplating of aluminium, steel, iron or zinc makes ...

How Electroplating Works. Electroplating is the application of electrolytic cells in which a thin layer of metal is deposited onto an electrically conductive surface. A cell consists of two electrodes (conductors), usually made of metal, which are held apart from one another. The electrodes are immersed in an electrolyte (a solution).

Cyanide-based solutions are the most commonly used electrolytes for silver electroplating. They are composed of silver cyanide and potassium cyanide, which allow for good adhesion and a bright silver finish. However, cyanide-based solutions are highly toxic and can be hazardous to workers and the environment if not handled properly.
