Surface treatment

Almost 100 per cent of produced parts, compounds and finished products pass through the surface treatment. The surface of metal parts can be coated either by powder technology or by liquid paint in two workplaces. The main decisive factors are the size and weight of individual parts. For powder coating, KOVAL SYSTEMS, a. s., uses a powerful automatic coating line by IDEAL LINE with a large mobile profile. Before the powder coat with the use of the electrostatic field is applied on the surface, there is the thorough preparation of the surface in a 5-degree continuous preliminary treatment in which anticorrosive surface treatment is carried out by phosphating and passivation. The parts are hung on a continuous conveyor and then fired in a furnace. With the Nova Verta Maxi Range 15 hand powder-coating line, you can coat large-size heavy products, weldments and single-piece series with their previously shot-blasted surfaces. The company uses two workplaces for lacquer coating, depending on the weight of the parts. Many parts, that have been bent and welded to the configurations, pass through an aperture before coating. The company has two independent workplaces to grind black and stainless parts. If the customer requires edges without spikes, the surfaces of parts are burring in the burring machines by Weber and TimeSavers.
