Co., Ltd. Founded on October 29, 2003, the company is a wholly-owned subsidiary of Qiankun Group Co., Ltd. and a national high-tech enterprise. It has three pillar industries: auto parts, blades, and heavy machinery. The racing engine connecting rods produced by the company have been selected by the world's top Formula 1 (F1) racing teams. It has successfully developed a series of innovative technologies, such as vibration aging and carbonitriding technology, in collaboration with universities including Sichuan University and Xihua University. These technologies can eliminate approximately 20% to 80% of the residual stress in crankshafts, significantly improving their service strength and fatigue life. Xinkun Machinery has also partnered with FAW Group to develop a V12 engine crankshaft featuring China's independent intellectual property rights, filling a critical gap in domestic V-engine production capabilities.
