Key components for electromobility

The future of mobility is electric – and electric drives require innovative hybrid components that meet the very highest standards of quality and reliability. At TB&C, this future has already started: e-mobility customers rely on TB&C’s core competency of combining thermoplastics, steel and copper to produce technically advanced hybrid components. The TB&C Electromobility Center of Excellence in Herborn unites bespoke engineering and fully automated production processes all under one roof. From prototypes to large series quantities for just-in-time delivery, TB&C is fully geared to meeting its customers’ needs.

System-optimized hybrid components

The electric powertrain in an electric vehicle is one complete system in which performance, efficiency and safety are paramount. As a partner with outstanding expertise in intelligent tool design, TB&C co-designs and produces electrical components. Our full focus here is always on quality, reliability and cost efficiency.

TB&C produces electrical components combining copper, steel and/or aluminum with up to 3 thermoplastics. The flexible manufacturing process allows the inclusion of bolts and bushings for easy assembly of the final product. TB&C offers optimal system integration with the utmost design flexibility, making components with very narrow tolerances and tight dimensions possible.

Our fully automated, integrated production sets standards in cost efficiency and quality. Each individual component undergoes automatic test processes such as dimensional testing, as well as high-voltage and leakage tests. QR codes guarantee full traceability of each component. The installation-ready components are delivered according to customer requirements..

TB&C E-Mobility Center of Excellence Herborn

Integrated production for drives of the future

TB&C pools expertise and innovative production technologies for e-mobility at its German site in Herborn. The highly automated shop floor is optimally aligned to electrical components and individual customer requirements; stamping, injection molding, assembly and end-of-line testing are combined into flexible production lines. Specialized software for toolmaking and tool maintenance planning is also part of the state-of-the-art production set-up. All this allows TB&C to implement customer specifications and guarantee consistent quality throughout the complete duration of series production.

Long-standing partnerships

TB&C has worked closely with OEMs and Tier 1 suppliers for many years. TB&C hybrid components have established themselves with leading car manufacturers, for example for sunroof mechanisms. TB&C has now expanded, adapted and secured these long-term partnerships geared to e-mobility.
