Traceability System for Engine Components at a Leading Automotive Manufacturer

A leading automotive manufacturer faced challenges with an incomplete traceability system for engine components during production. Due to the vast number of parts and frequent production batches, identifying specific batches and workstations in case of quality issues proved difficult, resulting in high recall costs and prolonged customer complaint resolution times.

Yuanjie Technology deployed the YJ-EM00 embedded QR code scanner for this customer at a critical point on the production line. The module supports DPM (Direct Part Mark) reading and operates reliably even in harsh conditions such as metal surface glare and oil contamination, enabling full traceability from part machining and assembly to final product inspection.

After implementation, traceability efficiency increased by 85%, and quality complaint resolution time was reduced from 3 days to 2 hours. Customers can quickly query production batch, workstation, and quality inspection records for any component via the system, significantly lowering recall costs and brand risk.
