In 2023, BYD will be the first to introduce our independently developed reamer gun cleaner at its Shenzhen production base as a pilot project for intelligent manufacturing upgrade. During the three-month testing period, the production capacity increased by 35% and passed BYD's rigorous technical acceptance for 54 items. The cooperation has continued until now, with a total reduction of 20% in production costs. Based on feedback from the production line, three system upgrades have been completed.
