       Both the product and the plant engineering side of the production process
        is constantly monitored. A detailed programme of periodic controls and
        preventive maintenance is applied to all machinery and installations in
        order to guarantee constant maximum efficiency. 
        The chemical compositions and operating parameters of galvanizing baths
        and correlated preliminary treatments are constantly controlled, as are
        the compositions and gradings of the ceramic blends that Bettini itself
        manufactures. 
        During all production phases, controls are carried out with regard to
        dimensions, dimensional tolerances, ceramic material shrinkage, integrity
        of pieces using penetrating liquid, thickness of applied coatings and
        surface roughness. 
        The single phases are self-control managed by operators and are always
        under the supervision of quality department staff.
