Dradura’s Last Generation Coating System Optimises the Powder Coverage of Metal Mesh Intersections Monica Fumagalli ipcm

In the coating field, is it possible to combine maximum production capacity, adequate film homogeneity in the most critical areas, and maximum paint savings? For Dradura, a company specialising in the processing and finishing of wire for household appliance and furniture components, the answer is yes – thanks to a latest-generation coating booth developed by Wagner, a hanging system designed by Rostirolla, and the plant engineering solutions featured by its O.M.SA. line.

he shape of an object determines its aesthetics and functionality: the task of a coating process is to cover its contours, thus enabling the film to settle on its surface. One of the most common problems
related to the application of coatings is the inhomogeneity of thicknesses between edges and flat surfaces. In the case of three-dimensional components with complex geometries, in particular, the major critical issues are found in undercuts and concave areas. However, the coating application operation is even more complex when it comes to optimising the spraying process on products made of wire and characterised by large mesh size. Indeed, as well as identifying the best application technology to avoid paint waste, it is also crucial to design the most suitable system for applying the correct amount of coating on wire mesh intersections and obtaining a homogeneous layer with the minimum thickness needed to meet customer specifications.
