Cataphoresis painting is a process which provides the immersion of a component into a bath composed by water thinned paint which complitely covers the surface of the immersed components through the current passage. The new introduced by us is the use of this particular process in the field of transparent painting for furnishings such as knobs, drawer pulls, bath accessories etc... This process has had very positive results. In the furnishings field it's very important that the covering is perfect, without superficial defects such as orange peel, colour heterogeneity on the surface or colour change. All this has been obtained by us projecting a sofisticate current rectifier which generates current that crosses the bath causing the adhesion of the painting on the component.

We project and build complete painting systems which have a pre-treatment section,  reverse osmosis equipment for water treatment, polymerization oven, rectifier, frame transport systems, ultrafiltration systems etc..
