Challenges in Coding and Marking on Batteries
The battery industry faces unique challenges in coding and marking products like lithium-ion and lead-acid batteries and even coding on automotive and aerospace parts. Batteries need clear and consistent lot codes to ensure traceability and compliance.
- Coding on Curved Surfaces: Most batteries have cylindrical or round shapes, making it difficult for traditional battery date coding and marking methods to achieve clear and legible codes.
- Printing on Small Areas: Battery components have limited surface space, making it challenging to print high-contrast, micro-precision codes.
- Keeping up with Rapid Manufacturing Pace: The rapid growth of the battery industry has led to shorter production cycles, higher throughput, and more frequent product changes, making traditional methods like manual labeling or stamping outdated.
