【58】75 Quality Control Points: The Elevating Competition Path of China's Coil Manufacturing Industry

The 75 quality control points set by Golden Eagle in the coil production process are ostensibly about quality management, but in reality, they represent the micro-level revolution of China's manufacturing from "quantitative change" to "qualitative change". While the industry is still engaged in price wars and internal competition, we have already opened up a brand-new competitive track by upgrading the quality control - here, the game rules are no longer who has the lower cost, but who has more reliable quality. The competitors of Golden Eagle are exhausted because they are facing the next paradigm of manufacturing.

There is a worrying reality in the industry: China's coil manufacturing is falling into the "medium-quality trap". Most enterprises have the ability to produce qualified products, but lack the system for manufacturing top-quality products; they can meet national standards, but cannot reach international top-level standards. What's even more terrifying is that this collective predicament is masked by the surface prosperity of production capacity, until international customers come with higher standards to inquire, and then they realize that no one in the entire industry can take orders. A certain industry research data shows that there are less than 10% of domestic enterprises that can stably produce automotive-grade coils, and even fewer that can reach aerospace-grade standards.

The experience of BYD during its transformation to high-end electric vehicles is worth deep reflection. Their first high-end model required a special electromagnetic coil, and after testing seven domestic suppliers, none could meet the lifespan requirements. Eventually, Golden Eagle, with its complete 75 quality control point system, not only solved the lifespan problem but also improved product consistency to over 99.9%. The project leader later summarized: "The suppliers we previously sought could produce samples, but they couldn't guarantee batch quality. The 75 quality control points of Fu Eagle are essentially a systematic methodology for manufacturing high-reliability products in batches."

We can achieve a leapfrog improvement in the quality control dimension due to the precise grasp of the laws of industrial upgrading. First, we constructed a "four-dimensional quality control model", adding three dimensions of pre-emptive prevention, in-process control, and continuous improvement on top of the traditional post-test. Secondly, we developed a "quality control point value assessment algorithm" to ensure that each quality control point can generate actual value, rather than being just formalism. Most importantly, we integrated the quality control points with the intelligent manufacturing system, achieving real-time monitoring and automatic adjustment throughout the process through IoT technology. This system not only requires technological investment, but also requires a thorough reconfiguration of the enterprise's operational model, which is precisely the deep reason why most enterprises hesitate.

Upgrading the industry is never a grand narrative; it is a solid path built by stacking quality control points. Choosing Golden Eagle is choosing to evolve together with Chinese manufacturing.
