Automotive Springs, Stamped Parts & Busbars: Key Applications

Automotive Springs, Stamped Parts & Busbars: Key Applications

From engines to EVs: how springs and stamped metal parts power modern vehicles

11/12/2025

Did you know a typical car or truck can contain well over 1,300 springs, stamped and bent metal parts, contact elements, washers, and flexible busbars? These small components are absolutely critical to the operation of any vehicle, whether diesel, gasoline, hybrid, electric, or even hydrogen. Compression springs, torsion springs, tension springs, valve and contact springs, wave springs, washers, and complex flexible strip busbar pieces all work behind the scenes to keep the vehicle running.

We at RPK Group have spent over 50 years designing and manufacturing these parts for the world’s leading Tier-1 and OEM automakers, delivering high-performance stamped and bent components that combine strength with versatility. In addition to our standard offerings, we provide custom design support and engineering solutions to meet the unique requirements of modern vehicles. Whether it's rapid prototyping or tailor-made components, RPK Group is equipped to provide the flexibility and innovation engineers need to solve new challenges.
