Flow drill fastening for electric vehicles
Learn more about our flow drill fastening applications for battery assembly
Challenges in battery assembly:
- Joint strength and leak tightness
- Removable cover for service requirements
- Repeatable fastening/tightening
- Electrical contacting
- One-sided access
- Large series production
Our solution for cover-to-tray joining:
Flow drill fastening meets high standards for joint strength and crash performance. With our K-Flow technology, the battery cover can be mounted to the tray with single-sided access. The joint is leak tight between fastener and sheet as well as between both sheets and it can be combined with a liquid gasket. At the same time, it is detachable to facilitate maintenance and dismantling. The metallic components are in a conductive bond and form a Faraday cage, which prevents electromagnetic interference. With short cycle times and high process reliability, it is suited for large series production.
