PVD and DLC coatings for automatic machines

The performance and productivity of your automatic machines take a step forward, thanks to coatings with advanced characteristics. Find the best solution for your packaging, food, beverage, pharmaceutical or textile applications.

Main benefits

Anti-wear, anti-friction and anti-corrosion

The full set of anti-wear, anti-friction and anti-corrosion properties of our coatings work together to give you innovative mechanical engineering solutions. PVD coated components become more resistant to very aggressive working conditions. They help solve problems of bonding and adhesion of residues. Moving parts glide better, reducing the use of lubricants. Our treatments are also very light and do not alter the inertia of the automation, which becomes more precise and faster.

And since our technology has minimal environmental impact, you know you are making the right choice to improve the performance and productivity of your automatic machines.

Extremely easy cleaning of machinery and components

The excellent release and anti-sticking properties combined with the extreme ease in cleaning machinery and components that our coatings guarantee will allow you to reduce maintenance times and increase productivity.


Total guarantee of food safety

The ceramic nature of our coatings makes them perfectly suitable for food contact and capable of meeting the highest standards of safety and hygiene. With us you have the guarantee of a range of products certified according to the European standard EN 1935 and accepted by the prestigious Food and Drug Administration (FDA).

Surprising, advanced. Our solutions enhance the critical components of your machinery.

Food & beverage

Working with sugars or salts means having surfaces that corrode, get dirty or get kneaded. Our coatings, thanks to their antisticking properties and their food compatibility, are the optimal answer to problems of resistance to corrosion, abrasion, gluing or cold welding.
In the beverage industry, the use of corrosive fluids can trigger adverse chemical reactions that are contrasted by coating the components in direct contact with the product or in its vicinity.
Tea, coffee, sugar, tobacco, pasta, jams, purees, there are countless examples of applications that greatly benefit from the use of PVD and DLC coatings.


In the pharmaceutical industry, hygiene, safety and accuracy are of the utmost importance. Our surface treatments are the optimal answer to problems of resistance to corrosion, abrasion, sliding and gluing. They guarantee excellent production standards in the filling, blistering and sintering phases.


We have developed specific solutions for this particularly demanding industry. Our PVD and DLC coatings are able to reduce problems of wear due to abrasion and gluing of the yarns and to extend the life of your components, including needles, vanes, cylinders, combs for looms, meshes and lamellas or ceramic inserts.
