PLC Controlled Automatic Electroplating Plant
AN ELECTROPLATING LINE CONSISTS OF PP TANKS, PLATING BARRELS, HANGING PLATING, RECTIFIERS, CENTRIFUGE DRYERS AND PLATING FILTERS.
Product advantages:
1.Corrosion resistance
2.High efficiency
3.Prolong the life of workpiece
4.Lower cost
Operating principle:
Barrel plating is an efficient and relatively low cost method of plating. Parts are placed inside a barrel that slowly rotates while it is immersed in the plating solution. Electrical contact is made through the use of danglers or centerbars that are located inside the barrel. This plating method is usually recommended since high volumes of parts can be plated with uniform coverage.
Electroplating Equipment
In electroplating, an ionic metal is supplied with electrons to form a non-ionic coating on a substrate. A common system involves a chemical solution with the ionic form of the metal, an anode (positively charged) which may consist of the metal being plated (a soluble anode) or an insoluble anode (usually carbon, platinum, titanium, lead, or steel), and finally, a cathode (negatively charged) where electrons are supplied to produce a film of non-ionic metal.
Our chief plating engineer contributed to Chinese plating industry standard drafting. We can customize various plating equipment as below:
Plating Methods:
Rack Plating
Barrel Plating
Continuous Plating
Brush Plating
Main Products:
Gold Plating
Gold plating is a method of depositing a thin layer of gold on the surface of glass or metal, most often copper or silver.
Silver Plating
Rhodium Plating
Rhodium plating is occasionally used on white gold, silver or copper and its alloys.
Chrome Plating
Chrome plating is a finishing treatment using the electrolytic deposition of chromium.
Zinc Plating
See also: Galvanization, Hot-dip galvanization, Electro-galvanization, Bethanization and Sherardising
Zinc coatings prevent oxidation of the protected metal by forming a barrier and by acting as a sacrificial anode if this barrier is damaged.
Tin Plating
See also: Tinplate
The tin-plating process is used extensively to protect both ferrous and nonferrous surfaces.
Alloy Plating
In some cases, it is desirable to co-deposit two or more metals resulting in an electroplated alloy deposit.
Composite Plating
Cadmium Plating
Cadmium plating is under scrutiny because of the environmental toxicity of the cadmium metal.
Nickel Plating
Compared to cadmium plating, nickel plating offers a shinier and harder finish, but lower corrosion resistance, lubricity, and malleability, resulting in a tendency to crack or flake if the piece is further processed.
