PVD and DLC coatings for Engineering and Industry

The careful search for ultra-performing mechanical engineering components finally finds a way to express itself. Exclusive solutions, in co-development with your idea of innovation, will improve the performance and lifespan of your components.

Main benefits

Countermeasure for abrasion, adhesion and corrosion wear

Precision mechanics, molding, textiles, oil & gas: these are just some of the applications that greatly benefit from the anti-wear, anti-friction, anti-corrosion and chromatic properties of PVD and PaCVD (DLC) coatings. Our know-how and our experience allow us to develop thin layers that differ in composition, hardness, friction coefficient, thickness, chemical inertness and color. By relying on our team of experts, you will be able to choose the best solution for the engineering of your product, based on the material, application and combination of problems you have to tackle.

Performance even in extreme conditions

Our solutions guarantee the total functionality of your components even in extreme conditions: low or high temperatures, in the presence of acids, in the absence of lubricants, in vacuum, below sea level or in applications where the risk of corrosion is very high.

Green technology

Global competition and environmental challenges require engineers and designers to choose the best solutions in terms of performance and sustainability. By choosing our vacuum deposition technologies, you improve the engineering qualities of your product and rely on a “green” technology with minimal environmental impact.

Surprising, advanced. PVD and DLC applications are almost endless.

Precision mechanics

We have requests for increasingly specific and complex applications ranging from the design of a turbine to that of rotors for compressors, geared reduction systems, electric motors, cogeneration plants … We coat wear and movement components such as gears, bearings, pumps, screws, spindles, valves.


Protecting molds and equipment with our surface treatments means extending their life cycle and reducing maintenance frequencies, thus generating significant reductions in industrial costs. We offer innovative solutions developed specifically for cold and hot molding (HDP X7) and for plastic and rubber molding (HDP X5).

Oil & Gas

In this industry, components work in extreme conditions of humidity, high temperatures, oily or muddy environments. Coatings such as DLC or TiN can improve the wear and corrosion resistance of valves and other components, improving their lifespan.

Why an STS coating?

We offer you a wide range of high-performance solutions able to meet your specific needs. We know how difficult it can be to choose a coating, as it requires technical expertise on materials, applications, heat treatments and deposition technologies.

This is why we put our experience and our know-how at your service to carry out the in-depth analysis of your project and guide you in the best choice of treatments and materials. You will have access to high-value services like STS Lab, STS Academy or the integrated management of complex processes.
