    • Optimised enamelling thanks to new application equipment

    Enamelling versus powder coating: two different worlds, two approaches to metal protection and finishing. Recently, cooking appliance manufacturer ELBA Italy has optimised its electrostatic powder enamelling process thanks to new application equipment supplied by Wagner S.p.A., capable of ensuring uniformity, precision, and superior aesthetic quality. Characterised by higher baking temperatures and greater film thicknesses than traditional coating, this is more controllable and efficient, with a significant reduction in rework and defects.

    The challenge of electrostatic enamelling: Our coating solution

    • The WAGNER powder application booth is used for oven casings, front panels, and rear components, and an enamelling system for treating cavities, sheet metal parts, drip pans, and side panels.
    • The enamelling booths are equipped with high-efficient enamel guns, featuring a charging voltage of up to 100 kV and automatic pressure control (AFC) to optimise powder adhesion.
    • To limit the build-up of vitreous enamel on the nozzles’ edges, the guns are designed with simplified circuits and ceramic nozzles that are highly resistant to wear.
    • The system allows for total recovery of the powder, which is mixed with fresh product and reintroduced into the application cycle.

    In the ovens and cookers manufactured by ELBA Italy, refined design and high performance are enhanced by high-quality finishes obtained through enamelling (mainly in black) and powder coating.

    The guns installed in the booth devoted to sheet metal parts are equipped with a double head and a dedicated electrode, as well as blowers above the nozzles to prevent powder accumulation.

     

    We chose WAGNER equipment both for its superior technical performance and because our coating department was already familiar with it. Indeed, it has enabled us to increase production efficiency and manage rework more effectively.
