Laser Cleaning & Marking Electric Vehicle Battery Modules

Battery modules have busbars and hundreds of poles that need to be cleaned before welding, so even a 1% inconsistency can lead to massive recalls. Laser cleaning provides the precision required to ensure consistent cleaning results and prevent quality issues.

The same laser can also be used to mark battery trays and EV drive units. With our unique marking technology, you can even engrave 2D codes that maintain traceability through shotblasting—which is ideal for EV drive units.

Keep up with short cycle times
Perform laser marking with the same laser

Benefits Of Laser Marking For Battery Trays

Mark multiple parts with the same machine and without fixtures
Leverage your existing robot
Minimize your footprint
Etch high-quality markings
Minimize your impact on cycle time with high-speed lasers

Benefits Of Laser Marking For Ev Drive Units

Engrave high-quality codes that maintain traceability through shotblasting
Ensure no defective codes make it to the end user
Keep up with short cycle times
Know the exact origin of defects to avoid large recalls

I was worried laser cleaning would be too slow, but Laserax had a solution for us. They proposed a turnkey solution with three 100W laser heads to clean all 1,200 zones on our modules. The total cleaning time with loading, vision adjustments, cleaning, and unloading was only 25 seconds—short enough to prevent bottlenecks.

When I saw Laserax’s video of the Open-Air machine, I was surprised someone manufactured a turnkey solution that perfectly fit our needs. Since our cycle time was long, we had room to add an extra step to our robot’s operation cycle.

In the die casting industry, we shotblast a lot of parts. Laserax’s technology is a game changer for us. It has allowed us to meet new traceability requirements and regulations, and be the first choice when applying for automotive OEM programs.
