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.

An automotive component manufacturer faced challenges reading a 10x10mm DataMatrix code laser-printed on rough, uneven piston rod surfaces during production. Water droplets and oil stains often covered the codes, causing significant reductions in contrast. Additionally, the vibration and high temperatures conditions further complicated the code reading process, making conventional code readers ineffective. These issues jeopardized the production line's efficiency and failed to meet the strict reading rate requirement of 99.94%.

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.

Manufacturer was seeking for a cost-effective solution for stable and high-rate reading DPM code on the LCD screen in manufacturing processing to replace the model they are using. To stable and no-one-miss reading the laser-marked DPM code on the LCD screen during moving is a challenge.

Recently, a well-known lithium-ion battery manufacturer was asking HEROJE for a better code reading solution for the battery winding process.
