[Shuanghuan Transmission: The differential small assembly business achieved significant growth in the first half of the year] On August 29, Shuanghuan Transmission stated in the agency conference call that the differential small assembly business achieved significant growth in the first half of the year. The company effectively solved the problem of heavy weight and accumulated errors through process innovation. Advanced problems have become the main source of increment; at the same time, based on technology accumulation, it has realized independent design and provided design empowerment for customers; because this business involves the procurement of sub-parts and assembly links, the gross profit margin will be lower than the company's full-process independent manufacturing business, but the overall business volume has grown well.
