Nanotechnology – 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.

UFG srl Chromium PVD
Environmental impact Very high Very low
Coating materials ABS, PC/ABS, PA PS, ABS, PC, PC/ABS, PMMA, PA
Available colors Limited: substantially chrome and nickel Very varied: effects silver, chrome, steel, copper, colored in general (yellow, light blue, etc.)
Surface resistance Great Good
Dimensions of the pieces From small to very large Small


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


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.

Other Finishes


The galvanoplasty provides for the laying of thin layers of metal on surfaces built with 3D prototyping system through FDM process, this process can be decorative or functional.


We offer coating service. The most common applications are aluminum, stainless steel and soft-touch effects, with different colors.

Other Services


Our steel assortment includes all the main special and stainless steels, thanks to which we are able to meet all the design and processing needs of our customers.

Thermal treatments

UFG srl provides its customers with heat treatments, such as hardening, tempering, solubilization, aging, nitriding, annealing, nitrocarburization, cementation, carbonitriding, etc.


Welding work. SMAW Shielded Metal Arc Welding, MIG welding ((Metal-arc Inert Gas), OFW – OxiFuel gas Welding, TIG welding ((Tungsten Inert Gas). These are some of our welding techniques.
