The client, a precision component manufacturer, encountered significant challenges in reading ultra-small DataMatrix codes (1x2mm) that were laser-marked onto tiny, slightly rough metal parts. The limited marking area, combined with uneven surface texture, often resulted in low contrast and partial deformation of the codes. These factors made it extremely difficult for standard code readers to capture clear and stable images. In addition, the inconsistent positioning of parts and variations in microstructure further hindered recognition reliability. The customer required a compact, high-performance solution capable of consistently decoding micro DPM codes with high speed and accuracy, all within a limited installation space and without disrupting the production workflow.

A metal precision manufacturer faced difficulties in reading both 5x5mm DataMatrix codes laser-printed on highly reflective parts at the same time in processing. The combination of low contrast and surface glare made it impossible for standard code readers to capture the code accurately, affecting the production line's efficiency.
