collaborated with a well-known baby product brand to customize lightweight frames for strollers. Using 6063 aviation aluminum alloy, integrally formed by precision CNC cutting and seamless welding processes, the frame weight is reduced by 35%, with a load-bearing capacity of 50kg, balancing portability and stability. The folding hardware structure is optimized with anti-pinch buckles, which are easy and safe to operate. The surface is anodized, scratch-resistant, wear-resistant and not easy to fade, suitable for strollers for 0-3 year olds. This customized frame helped the partner increase the product qualification rate to 99.9%, with sales increasing by 52% year-on-year, becoming the core supporting product for the high-end baby stroller market.
