collaborated with a rehabilitation device manufacturer to customize metal connectors for intelligent prosthetic joints. Using high-strength aerospace aluminum alloy materials and five-axis linkage machining to ensure smooth joint rotation, the prosthetic response delay was reduced to 0.02 seconds, adapting to the daily activity needs of patients with different body weights. After the launch of this prosthetic limb, it helped the partner increase the revenue of rehabilitation devices by 62%, enabling thousands of people with lower limb disabilities to regain their mobility.
