Quality is not a bonus - it’s essential

PASS is quality.


Quality management from development through to serial production.

Our highly qualified lab teams in Germany and Poland work with state-of-the-art tools to monitor our rubber mix formulations and guarantee the level of quality required to meet the specification.
Our experts develop our new products and processes following the latest project management methods. To do this, they use our own purpose-built technical centre.

Most measurements and analyses are performed inhouse.
Welding inspections and deployment simulations are also conducted using our own equipment.

Quality standards.

A zero-defect goal is expected within the automotive industry. We can only achieve this goal through systematic quality planning during the project phase. Pursuing this goal further means that continuous improvements to our customer service, our production methods and our internal processes are necessary.
