The world's most advanced forging production lines were built in Inner Mongolia (China). The investment for this project was of 24O million RMB and the annual sales turnover is estimated to 600 million RMB. It has a capacity of 300 000 crankshafts per year. Before it needed 200kg for each crankshaft, whereas it now only needs 180 kg. Therefore, the requirements of raw materials were reduced, as well as the energy needed and the cluttering of the machines. Since April 2, the Yiji group is the largest producer of crankshafts in China.
