TRUMPF has developed laser applications that improve adhesive and coating preparation in battery production and enhance corrosion protection for aluminum components used in electric vehicles (EVs). These advancements support safer, longer-lasting batteries and more sustainable vehicle manufacturing.
Selective surface processing with lasers offers a clean and efficient alternative to chemical methods in automotive production. The process enables high adhesive strength for coatings and bonding while eliminating the need for aggressive chemicals.
In EV battery assembly, short-pulse lasers clean and prepare surfaces of battery cells and trays before coating or bonding. The ultra-short light pulses remove oils, oxides, and residues without damaging the material, ensuring stable adhesion and extending battery life.
Laser technology also strengthens corrosion resistance in aluminum components used in vehicle structures and electric motor housings. By selectively remelting a few micrometers of the surface, the laser homogenizes and rapidly quenches the material, preventing crevice corrosion even under harsh conditions such as salt exposure.
For large-scale applications like gigacasting, TRUMPF’s TruMicro Series lasers combined with PFO33 scanner optics enable high-speed surface processing suitable for automated production lines. The system can move laser pulses across components at speeds of several meters per second, supporting efficient series manufacturing.
Laser-based surface processing reduces chemical waste, tool wear, and energy use, contributing to lower CO₂ emissions and improved sustainability across EV manufacturing operations.
