Doratura Manerbiese operates in the “decorative” sector by carrying out galvanic treatments that affect the aesthetic appearance of the metal components.
We specialize in gold plating, silvering and copper plating treatments on metals such as: iron and its alloys, copper and its alloys, tin and its alloys and stainless steel.
Generally, the processing of the article begins with a preliminary cleaning of the piece and an alkaline degreasing to remove the grease and oils from the surface of the pieces. The process involves washing systems with water-based products and then polishing with nickel. To guarantee a longer duration to abrasion, handling the atmospheric agents and to avoid the appearance of stains, the surface is usually coated with an intermediate layer of nickel before and after the copper plating and then we proceed with the finish to obtain according to the request of the customer: gilding, silvering in its variants of glossy, satin or antiqued and copper plating.
–Gold plating is widely used to ennoble ornamental objects and for this reason, we use generally thin but sufficiently protective coatings that give particular colors to the surfaces. Gold, the most ductile of metals, can be transformed into leaves or very thin threads, but it is also very resistant to corrosion.
-The decorative galvanic silvering is carried out on different metals to obtain purely aesthetic finishes.
We produce matt-satin and glossy silvering. The first one, once released from the silver plating baths, requires a further finishing operation to give a shiny or opaque-satin appearance. The shiny silvering produces directly shiny deposits.
Generally the operating cycle for the decorative silvering of copper objects and its alloys, or alloys of tin, zinc, etc. provides:
- cleaning
- degreasing
- washing
- pre-silvering
- silvering
- washing
- drying and finishing
Nickel plating is one of the most widely used techniques in electroplating treatments for the appearance it gives to objects, but above all for the protective value and the hardness which can vary depending on the bath used.
The various types of nickel plating are distinguished according to the thickness of the coating: if thinner it will guarantee a decorative and corrosion-resistant final layer, if thicker it will guarantee greater resistance to abrasion.
