SILMADE NCVM PVD COATING

Innovative technology for coating car keys

The vehicle key as an overall work of art: small, compact and yet with the highest requirements. Of course, a luxury car also needs a key whose feel and look reflect the value of the car. We finish keys with partial chrome surfaces that are scratch-resistant, abrasion-resistant and chemical-resistant.

This makes a so-called “non-conductive” (NCVM) – i.e. electrically non-conductive – chrome surface necessary. This coating is intended to prevent a Faraday cage and thus the shielding of radio signals between the vehicle key and the vehicle.

Your task

Electrically non-conductive chrome surface
Maintaining the functionality of the transmission power
Avoidance of a Faraday cage
Feel and look that reflect the value of the car
High scratch resistance and durability
Abrasion and chemical resistance

Our implementation

Using the PVD process, we adjust the electrical conductivity precisely to your customer requirements and reduce or increase it as needed.

We can use the process to produce conductive layers for shielding, dissipating electrostatics or as an EMC layer, as well as high-impedance layers that hardly affect radio, radar and sensors.

Electrically non-conductive (NCVM = non-conductive vacuum metallisation)
Very low interference with radio signals
Inductive charging despite coating
Very high resistance to abrasion, scratching and chemicals
