Manufacturer Details Aging Test Method to Reduce Return Rates

Ningbo Mengting Outdoor Implement Co., LTD., a manufacturer of outdoor equipment, has detailed a four-phase aging test protocol designed to significantly reduce product return rates. This method, implemented in collaboration with a Chilean outdoor retailer, has reportedly decreased headlamp return rates by 35% by identifying and rectifying common failure modes before products reach consumers.

The protocol targets the four primary causes of rechargeable headlamp returns, which collectively account for approximately 90% of all product returns. These identified issues include battery capacity degradation, LED light output reduction under high temperatures, solder joint failures on printed circuit boards due to thermal shock, and the deterioration of headbands and waterproof seals from ozone and UV exposure.

The four-phase testing procedure involves battery cycle and capacity drop tests, LED aging under high temperatures (60°C), PCB thermal shock testing with visual inspection of solder joints, and exposure of headbands and seals to ozone and UV radiation. This comprehensive approach aims to ensure product durability and reliability across various environmental conditions.

To ensure consistency and repeatability across production batches, the process includes five key steps involving supplier coordination. These steps involve formalizing test protocols and acceptance criteria, integrating testing into the production schedule, documenting results for each unit, and sharing reports with buyers prior to shipment. The company recommends full pre-shipment aging tests for mid-sized batches, ranging from 500 to 5,000 units.
