PVD or galvanic coatings?
PVD comparison – galvanic coatings (chrome plating)
The galvanizing plating systems present very high risks for workers’ health and for their high environmental impact.
The substances used are in fact very dangerous and must be handled with great care. The costs of disposal and water management are high and it is now extremely difficult to obtain the provincial authorizations for the installation of new plants.
PVD coatings, on the other hand, have zero environmental impact when it comes to metal deposition and very limited for painting operations, actually presenting itself as an interesting alternative to the growing sensitivity towards the environment and working conditions.
As far as coated materials are concerned, PVD treatments also have clear advantages, since they can be applied to a very wide range of polymers, zamakas and glass; instead, galvanic coatings are confined to ABS and PC/ABS only.
A further advantage of PVD coatings is the chromatic range obtainable, ranging from metal effects to colored finishes.
Concerning the duration of the coating, the chrome-plating has better scratch and chipping resistance characteristics. It is therefore successfully used in very severe applications (eg car front grilles), both indoors and outdoors.
PVD treatments are instead recommended only for indoor applications or with modest outdoor use.
The chromium plating can then be performed on both very small and very large pieces (depending on the size of the tanks), whereas the PVD is limited by the dimensions of the high vacuum chamber.
In conclusion, therefore, each technology has advantages and disadvantages, to be assessed in relation to the type of product to be manufactured, operating conditions and sensitivity to environmental pollution.

What are the services of UFG srl and the advantages in using them?
We make your pieces from your 3D CAD file, technically delivering better results than 2D drawing. But not only that, because the use of cutting-edge software combined with the assistance of a team of CNC experts will help you solve any problems and facilitate your work process.
What equipment does the UFG have?
Your pieces will be created by latest generation 2 to 5-axis milling cutters and lathes, as well as Cormant and Iscar tools and CAM HyperMill software.
What advantages does UFG srl offer to professionals in the sector?
You will have a professional, fast and reliable supplier. You will receive within 48 hours the most suitable quotations and offers for your needs.
I do not have a CAD / 3D model. Can you create one for me?
No problem! By providing us with your PDF / 2D file, UFG creates the 3D file for you thanks to a team of qualified designers. Find out more!
Why should I do my pieces at the CNC rather than rapid prototyping technologies, such as 3D printing or metal sintering?
Machining with CNC machines allows you to obtain advantages in the consolidated and extremely precise manufacturing processes that offer a technically superior and ready to use product, all with much faster times and lower costs compared to 3D printing. The materials used in the production can be the final ones and not the prototypes that have only the shape. Discover details on milling.
