"Baotou manufacturing" has promoted the high-quality development of the city's industrial economy and taken it to a new level.

The growth rate of companies above designated size in the city increased from January to July, climbing 23.4 percent from the previous year as a result of their innovative development.

At present, many leading enterprises represented by HYSOLAR, GCL New Energy, and Daqo have gathered in Baotou. The city has rapidly developed a crystalline silicon industry, and expanded the scale of the related upstream industry.

In the fully automated double-track intelligent production workshop of Baotou Jiangxin Micromotor Technology Co, which uses mechanical arms, more than 13,000 voice coil motors are produced every hour. The company expects the factory will be fully automated by the end of the year.

Standing next to a domestically produced, 300-metric-ton mining truck that measures 15.8 meters long, 9.7 meters wide and 8.3 meters high, one cannot but wonder at this marvel of industrial manufacturing. Prior to the development of this truck, the key core components in the engines and electric drive systems of China's mining trucks all came from overseas.

After three years of R&D, the joint research and development team of Inner Mongolia North Heavy Truck Co successfully overcame the difficulties in producing engines for large mining vehicles, electric drive systems, and suspension technology.

The team produced China's homegrown technologies in such areas as power transmission systems, the design and manufacturing of large structural parts, and improvements to vehicles' information and intelligence. This has resulted in the independent and controllable manufacturing of key core technologies for mining trucks.

Mingyang Group recently produced a 7.15-megawatt ultra-large onshore wind power machine and ultra-long onshore wind power blades with an impeller diameter of 216 meters. At present, the whole machine and blades have been delivered to projects in Inner Mongolia autonomous region, filling a local industrial gap.
