The need to provide the customer with a complete product has prompted the company to create a series of processes "additional" to the galvanic process allowing the customer to get a full product without any additional steps and logistical transfers, while creating a significant time advantage and money to the customer.
Burring working by means of sandpaper. It removes all imperfections due to the injection during the die-casting process.
Finishing process that follows the grinding working. We make use of urea stones that level the surface.
The polishing makes the surface smooth, homogeneous, shiny and free of porosità.
It is possible by using vibro-tumblers with different techniques and materials, such as Semolina polishing, chemical agents, ceramic polishing.
The electroplating is a process whereby metals are electrolytically deposited on various substrates (eg zinc plating, nickel plating, chrome plating, oxidation, etc ...)
Today the electroplating industry is an important sector and allows to treat variety substrates, giving the piece, the characteristics of the deposited metal, even with very thin thickness. The galvanic processes can be divided into operations of electroplating and electroforming. The electroplating is the set of techniques for coating metal surfaces with other metals or alloys, electroforming includes techniques of coating metals with non-metallic surfaces. Thanks to these electrochemical processes is possible to coat an object of metal or plastic with a metal more precious (eg. silver, white bronze, brass, copper, gold, nickel, etc.). The galvanic treatment can take two main characteristics depending on the final result; will have technical electroplating when the main purpose is to protect from corrosion and oxidation materials that otherwise would deteriorate quickly in contact with air and moisture such as iron or copper, while when it gives the object will have decorative surface aesthetic properties that make it a artistic element and design, also the decorative finish exerts a protection against aging of the material. Of course with the development of production techniques have improved galvanic also all the processes that break down and purify the waste production to create an increasingly more in line with the philosophy of environmentally sustainable development.
The discovery of the galvanic technique is attributed to Luigi Galvani, from which this technique takes its name, around 1791, then in the early years of the '800, with the discovery of the voltaic cell or electrochemical, year is the first experiments of electrodeposition of copper, gold, silver under Luigi Brugnatelli. From there a long series of experiments and trials conducted by numerous scientists and scholars led the galvanic today, techniques, products and equipment keeps getting better.

The quality and permanence of our galvanic treatments on substrates such as zama, iron, brass, and steel are the result of a long experience in the field and this is the best visiting card for all companies.
Galvanic Gesm S.p.a. production plant is logistically placed in three modern automatic plants. These plants are exclusively rotary barrels and are equipped with several management technologies: From the electromechanical technology to the laser technology.
High productivity and reduction of manpower allow a considerable reduction in costs if compared to loom finishing. This is no doubt an unquestioned advantage for our customers. And without giving up quality, even on much polished surfaces or on large surfaces on which the result is fairly close to static galvanic treatments.
The constant evolution of its finish is one of Gesm SpA’s strength, concentrating on high quality and respecting the ecosystem.
This evolution is the result of a close cooperation with its customers or its designers in the analysis and development of new “colours,” depending on their requirements; your fantasy is not an utopia to Gesm.
We can also create all kinds of coating and “colour,” both starting from a metal sample or not.
Post treatments are carried out after the galvanic electroplating and consist of a series of bronzing, painting, sandblasting that give special colours at the material: From the classical antiques to the modern paint colours.
Are various processes and abrasions to create gradient effect made antique and aged by time.
Thanks to the use of microballs, you obtain an opaque and smooth deposit.
The zapon painting is the immersion of the products to be treated in special paints, which can be water-or nitro and their subsequent drying centrifuge. This process creates a protective layer to the external agents, ensuring the quality of the product in time.
Colored paints nitro, epoxy or water are applied with different techniques and equipment. The rotover allow to fulfill in a single automatic working cycle the coating phase and the drying phase.
