SPLINTER-FREE PVD COATINGS

Decorative ring for steering wheel emblem

In the event of an airbag firing, the components are subjected to immense accelerations. Airbag caps and all attachments are safety-relevant components that are designed to protect the driver in the event of a crash and must not injure them. The worst-case scenario is flying components, splinters or particles. These would become dangerous projectiles.

These requirements also apply to the trim rings and emblems, which are firmly attached to the airbag caps. Despite these environmental conditions, design elements should meet the highest visual requirements and high quality standards.

Your task

No splintering of the metal layer when the airbag is fired
High quality and optical brilliance
Temperature range from -40°C to +105°C
Weldable, scratch-resistant, abrasion- and light-resistant

Our implementation

A completely splinter-free coating is a basic requirement for metallised emblems that are applied to airbags. A wafer-thin metal layer is applied to hard or soft thermoplastic materials using the PVD process. The metal layer is so flexible that it neither detaches nor splinters when the airbag is deployed and the component bursts.

In short, there is no risk of injury from flying particles or sharp-edged metal parts.
