The technique of the electrostatic powder coating is based on the fact that opposite electrical charged particles attract each other. Therefore, most of the conducting or thermally resistant solid bodies are suitable for powder coating.
High requirements like impact strength and weather resistance make the powder coating essential. Those properties caused industries like toolbuilding, engineering, medical technology, heating and ventilating engineering, home appliances, shop and furniture construction, as well as the automobile industry, to convert from wet lacquer to powder coating to a large extent.
With the help of injectors, the afore fluid-like coating powder will be pumped to the air gun, electrostatically charged by an integrated high voltage generation and emitted in the direction of the object. An electric field is generated between the earthed, normally conductible workpiece and the air brush (?) gun. The powder particles follow and adhere to the workpiece. Afterwards, the workpieces are transported into a dryer, in which the plastics powder is melting with the workpiece and hardening at 160 to 200 ° Celsius. Since the powder coating method goes without solvents, this technology is especially eco-friendly.
