Direct Part Marking (DPM) codes on metal components are widely used for permanent part identification in automotive, aerospace, and industrial manufacturing. However, reading these codes is challenging due to curved surfaces, reflective materials, oil contamination, and low-contrast laser or dot-peen markings.

A high-performance handheld DPM scanner enables stable decoding of 2D codes on metal and curved surfaces by using advanced imaging and decoding algorithms designed for difficult marking conditions. It ensures reliable code capture even on cylindrical parts, machined surfaces, or worn markings, allowing accurate component identification during production, inspection, and maintenance operations. This improves reading stability, reduces scanning failures, and supports efficient industrial workflows.
