collaborated with a well-known domestic automobile enterprise to customize precision hardware adjustment brackets for car seats. Using high-strength 45# carbon steel, formed by precision stamping and quenching processes, the bracket can bear a load of 150kg, enabling multi-gear adjustment of the seat’s front and rear, height. The gears are tightly engaged, adjusting smoothly without jamming. The wear-resistant rotating shaft design extends the service life by 3 times. The surface is electrophoretic rust-proof treated, resistant to high temperature and humid environment in the car cabin, suitable for seats of various models such as sedans and SUVs. This customized bracket helped the partner increase the seat product qualification rate to 99.9% and the sales of supporting models by 22% year-on-year.
