China's camshaft industry

The integration of China's camshaft industry and new energy industry is essentially a structural transition from traditional power components to high-precision and cutting-edge new energy supporting systems. In plug-in hybrid (PHEV) and extended range vehicles, the camshaft is still the core component of the internal combustion engine, responsible for precise valve timing function, and its demand is not decreasing but increasing - a single PHEV is equipped with an average of 1.2 high-performance camshafts, which emphasizes lightweight and low friction more than traditional fuel vehicles. The industry has achieved a weight reduction of 25% -53% through a combination of camshafts (hollow steel tube core shaft+split cam), and widely adopts laser quenching and high-frequency induction quenching processes, making the surface hardness of the cam reach HRC60 or above, increasing wear resistance by 40%, and meeting high-speed and high load conditions. The manufacturing end is fully intelligent, and Chongqing Jinqiao Manufacturing has built a 100% automated production line, with a 40% increase in per capita efficiency and an 87% reduction in production cycle. The monthly production capacity has exceeded 600000 pieces, ranking first in the country; Enterprises such as Ningbo Huaxiang and Yaxinke have deeply penetrated into the supply chains of new forces such as BYD, Ideal, Xiaomi, and NIO, becoming 'hidden champions'. The 14th Five Year Plan for the Development of the Automotive Industry lists efficient transmission systems as a key direction, promoting the upgrade of camshafts from 'engine parts' to 'key components of new energy powertrains'. China is leading the global high-performance camshaft technology standard system.
