How Notter GmbH developed a deep black coating once considered impossible

Business Case: Notter GmbH „Deep Black“

Following a customer enquiry from the automotive sector, Notter GmbH was confronted with the task of developing two different black shades for PVD coatings. The components to be finished with the two PVD coatings were to be used exclusively in the vehicle interior (decorative area). A "light" black tone had to be developed on one side and a "dark" black tone ("Deep Black") on the other. The "light" black tone corresponded to the colour tone of a-C:H coatings for tool coating and did not pose a major challenge for Notter GmbH. The "Deep Black" shade could not be deposited even after enormous efforts by Notter GmbH using PVD technology.

Not being able to fulfil customer wishes? That's not possible at Notter at all.

That is why Notter GmbH decided to consult an external consultant for decorative PVD coatings. Based on an extensive internet research, especially on social networks, and a first virtual meeting, Notter GmbH decided on Avaluxe as an external consulting company.

Challenge accepted! You can do it, says Avaluxe.

Within half a working day, Avaluxe successfully deposited the colour shade "Deep Black" on different substrate materials (e.g. brass, stainless steel, glass). It is noteworthy that the PVD coating equipment already available at Notter GmbH was used exclusively for the layer deposition.
