The quality inspection standards for forgings in new energy vehicles are the same as those for traditional automotive forgings, mainly including appearance inspection, dimensional accuracy testing, material structure and mechanical performance testing, etc. Additionally, due to the special usage conditions and environmental requirements of new energy vehicles, some additional and more meticulous inspections are also necessary.
In accordance with national policies, in order to standardize product quality management, the General Administration of Quality Supervision, Inspection and Quarantine issued the “Regulations on Quality Supervision and Spot Check of Automotive Forging Industry Products” in 2019. The regulations establish strict quality control standards and inspection plans specifically for the automotive forging industry. Meanwhile, the regulations also mention some common forging defects in new energy vehicle industry, such as burrs, cracks, etc., and corresponding detection methods.
In addition to national policy guidance, in actual production, some forging manufacturers also adopt more stringent quality inspection standards. For example, Nanjing Wuzhou Forging Co., Ltd. sends all of its lithium battery separator nail products to the qualified inspection department for precise measurement, material testing, and simulated stress testing to ensure that the products fully meet the quality requirements.
In conclusion, the quality inspection standards for forged components in new energy vehicles are basically the same as those for traditional automotive forgings, but also need to consider the special usage environment and requirements of new energy vehicles. Furthermore, in actual production, manufacturers can formulate more detailed quality inspection standards based on the characteristics of their own products to ensure that the products meet customer needs and market standards.
