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.

With the growing demand for automation and digital traceability in the automotive industry, accurate and reliable production processes are critical. Many manufacturers integrate Direct Part Marking (DPM) code reading technology to ensure quality control and traceability. However, this comes with challenges:

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%.

In the electronic PCB industry, the process of reading codes is a crucial step in ensuring the accuracy and efficiency of the manufacturing process. This step typically involves the use of code reading equipment, such as barcode scanners or fixed code readers, to capture and interpret the unique codes and identification markings on the PCB boards.

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.

A leading television manufacturer faced a significant challenge in their production line: reading a 5x5mm DataMatrix label code positioned at a 40-degree tilt and over 210mm away. Traditional code readers struggled with the label's small size and difficult angle, causing delays and inaccuracies that impacted overall productivity.

Manufacturer was seeking for a cost-effective solution for stable and highest-rate reading label-based code on the Auto Parts in quality inspection processing to replace the model they are using. To stable and no-one-miss reading and easy to integration.
