On January 24, 2025, BYD initiated a large-scale recall campaign due to potential safety hazards in the production process, involving 6,843 of its Tang豹5 hybrid models. The core issue lies in the risk of insufficient tightening of internal connection bolts within the dual-motor controller, which could lead to the generation of electrical arcs and even fires while the vehicle is in operation. This incident serves as an alarm bell for quality in the fastener industry.
As the "mechanical joint" of industrial equipment, the seemingly ordinary bolt carries the structural stability of key components. This accident tells us that a 0.01mm assembly error can evolve into a safety hazard that threatens lives and property. Torque control and anti-loosening detection in the fastening process are indeed the unbreachable quality red lines for manufacturing enterprises.
In today's transformation and upgrading of the manufacturing industry, quality control has long surpassed the purely technical realm and is a concrete manifestation of an enterprise's core competitiveness. Only by treating every bolt as the lifeline of their products can fastener companies solidify their safety defenses in the fierce market competition.
