For further product developments and research into new products and applications for S-Ply® leaf springs, Prause Durotec cooperates with industrial companies and scientific institutions.


Bühner & Schaible / University of Karlsruhe


In cooperation with the company Bühner & Schaible and the University of Karlsruhe, a new high frequency drive spring has been developed, based on the piezo effect; the so-called PKF-element (Piezo - Keramische – Feder = piezo – ceramic – spring). This technology provides extremly gentle, „gliding“ conveying, which is well suited for shock-sensitive products like pharmaceutical tablets. This world novelty is already in use in high frequency friction welding plants for thermoplastic profiles.
