PVD
UFG offers among its services the coloring and decoration (PVD) of plastic parts through nanotechnology.
Through the PVD (Physical Vapor Deposition), that is the deposition in the vapor phase, it is possible to obtain metallic, shiny and satin-finished surface finishes, with aesthetic characteristics of great value, not reachable with traditional methods, similar to galvanic treatments.
Through the metallization of plastic, metal materials such as aluminum, steel, chromium alloys, copper, gold, silver can be deposited on substrates (in plastic, zamak or metal sheet in our case).
The process takes place inside a closed chamber, in which a vacuum is generated, after which the “production” phase of metal steam that covers the pieces begins. The environmental impact is zero.
The product thickness is very reduced (we are talking about nanometers / micron) and it is also very delicate, therefore a protective coating is required. More paintings are often required, among which the metal called “sandwich” of layers is incorporated.

Materials
PVD coatings are applicable to these plastics:
- PEEK
- PS
- ABS
- PC
- PC/ABS
- PMMA
- PA
- POM
- PET
- Technopolymers
PVD treatment is also applicable to ferrous and non-ferrous metals and composites:
- Alloy steels
- Stainless steels
- Brass
- Bronze
- Aluminum and its alloys
- Titanium
- Composite materials in general
Design
Through the new technologies it is then possible to have a very wide range of colors, with effects chrome, steel, silver, copper, with glossy, satin and metallic effect.
Given the dimensions of the treatment chamber, the technology is suitable for the treatment of small to medium pieces.
Product sectors: furniture, sports, electronic, chemical, medical, lighting.
