Electro Painting

Electrodeposition is a well known method of applying priming coats on conductive substrates. The technique was first used in the 1960's in the USA for priming car bodies. Since then it has become widespread in industrialised countries, particularly in Europe.

In addition to the car industry, the metal coating industry has adopted the process for car accessories and spare parts, metal furniture, sectional steel, washing machines etc. The substrate is generally steel, with or without prior treatment but the process can also be applied to aluminium and other metals.

Items for processing passing through multi stage spray Pre treatment supported from overhead conveyor. Zone lengths determined by required process times and conveyor speed. Spray jet assemblies mounted in easily adjustable joints fitted in spray headers of either PVC, ABS copolymer, mild steel or stainless steel to suit temperatures.

Until the end of the 1970's the article to be painted was connected to the positive pole of an electric source and the process was known as anodic deposition. Since then another technique has appeared, cathodic deposition, in which the article is connected to the negative power.

The main virtue of the electrodeposition process is the possibility to coat objects of variable geometries with an extremely uniform layer yielding excellent corrosion protection.

The Ercon Group has over the past several years designed and installed both anodic and cathodic style plants for many blue chip companies, including Hitachi, Toshiba, Magna Seating whom are subcontract to Ford Motor Company, Foleshill Plating and Man Trucks.

The size of tanks installed varying from 3 cubic tonnes to 120 cubic tonnes. The variety of components coated covered the full spectrum of manufacturing industries.
