PVD coating
Noble is the tool, helpful and good…

… and if possible, also very durable! Because wear-resistant, hard-wearing tools are the key to efficient production. The magic word in this context is PVD coating (Physical Vapor Deposition) – a synonym for durability, higher productivity and lower production costs for manufacturing companies and toolmakers.

PVD technology: Trust in our experience

Industry and trade have long relied on physical vapor deposition (PVD for short) when it comes to optimizing the performance and resilience of their tools and components. For over 30 years, we have been valued as the ideal partner for customer-specific developments in the field of surface optimization and PVD coating.

The perfect PVD coating for your application

Hard, harder: PVD coating! Our wear protection processes and our expertise push the limits of your tools to the limit and enable maximum performance when machining demanding materials.

With a coating that is only 2 to 10 thousandths of a millimeter thick, we make tool steels, powder metallurgical steels and carbides so much more resilient that the service life of your tools is significantly extended. Will this transform your production? In any case.

Which of our products or PVD processes is best suited to your applications depends on both the intended use and economic considerations. We can say from experience: The optimum coating is always individual and is adapted by us to the requirements of your tool material and the requirements of the respective tool design.

PVD Beschichtungen Performance

Better performance for your tools

PVD coating for tools has long been the game changer in the modern manufacturing industry. In a world where every second counts, they can drastically reduce the downtime caused by tool changes. On the one hand, because they are robust and protected against corrosion and abrasion.

On the other hand, due to improved demolding behavior, especially with complex injection molds and drawing/forming tools The manufactured parts slide out of the mold much more easily.

Surface finishing – so useful, so fascinating

In the industry, there are various PVD processes that differ in their methodology: electron beam evaporation, magnetron sputtering and arc evaporation.

Due to the high adhesive strength of the layers produced, we rely on the arc process (Arc PVD) – exclusively and on the basis of our own developments, which are the result of our decades of experience as well as market and customer requirements.

The science behind PVD coating is as useful as it is fascinating. In a vacuum chamber process, metallic materials are vaporized and react with one or more reaction gases to form so-called hard material layers, as they are also known due to their ceramic properties. When applied to the tools, they form an extremely thin but very adhesive protective layer.

PVD process: How arc vaporization technology works

An arc is used to convert a solid metal target into a gaseous state: An electric arc is ignited between the material to be vaporized, the cathode, and an anode, which is nourished by the vaporized material itself and moves more or less randomly across the cathode surface.

Due to the high energy density in the cathode spot – the contact point of the arc on the solid cathode – material is removed there.

Common metals that are used in high-purity solid form as coating materials include titanium and chromium, as well as alloyed cathodes made of titanium-aluminum and chromium-aluminum.

As a result, there are also various PVD coatings such as TiN , TiCN , AlTiN , AlCro or CrN Each with unique properties suitable for specific industrial applications and excellent adhesion strength.

Your PVD coating: Holds, fits, has no air

A PVD coating adheres to the surface purely adhesively and does not penetrate the base material! Due to its high hardness, it is also brittle and only adheres due to the low layer thicknesses. It is therefore also known as the “thin layer”. Because it is within all tolerances, it does not affect the tool geometry in most cases.

As a customer, you can rely on maximum adhesive strength without having to worry about a loss of hardness, distortion or any influence on the microstructure of the steels or carbide – provided the material has been tempered at a minimum of 200 to 250 °C.

More performance layer by layer

Depending on the internal structure of the coating, we speak of monolayer, multilayer or nanolayer coatings.

  • With monolayer coatings, the base material and the coating surface have the same composition throughout.
  • With multilayer coatings, different individual layers are laid on top of each other. This combines the favorable properties of the individual layers and reduces residual stresses.
  • Fully automatic process sequences allow any number of different layers to be superimposed within a single shift. As the thickness of the individual layers is only nanometers, these layers are referred to as nanolayers.

  • Security technology

Important for all coatings!

A PVD coating is there to protect a perfect production tool from wear and make it even more durable and not to compensate for faulty tool preparation – even if it could in theory and sometimes in practice. In other words, the efficiency of any coating also depends on the correct preparation and condition of the tool, especially its surface.

PVD coating summary: The most important facts in brief

PVD coatings improve the surface properties of tools by applying a very thin but extremely robust coating using physical vapor deposition. The PVD coating extends the service life and optimizes the performance of the tools.

Yes, the PVD coating makes the tools harder and more resistant to abrasion, corrosion and other signs of wear.

The longer service life reduces the downtime of the tools and they need to be changed less often. This directly reduces production costs . In addition, the lower friction enables greater process stability and faster cycle times.

Cutting, punching, drawing and forming tools as well as plastic injection tools and molds. Occasionally also prefabricated parts.

The different PVD coatings have specific properties and are therefore suitable for different applications and materials. You can get a good overview on our product pages.

In the CVD process, the tools are exposed to considerably higher temperatures, which means that hardness and dimensional accuracy suffer.

A major advantage is the higher adhesive strength that results from the higher energy level of the impinging atoms. The arc process is therefore more suitable for coating heavily loaded tools. Optically, however, the sputtering process can enable more gloss and also multi-colors, which benefits optically relevant layers.

The tool is then simply recoated. In some cases, thanks to a Duo-Coat layer, you can visually recognize when the layer is used up and initiate a new coating before the base material is reached.
