As an emerging forming technology, as another effective way to strengthen stamping parts, it has broad application prospects in the automotive field. More and more foreign models, including economical cars, have adopted hot stamping parts; domestic, European and American models also widely use steel plate hot stamping parts. Typical body parts suitable for hot stamping mainly include front and rear door left and right crash bars, front and rear bumpers, A-pillar reinforcement, B-pillar reinforcement, C-pillar reinforcement, floor channel, roof reinforcement beam, etc.
But in general, the crash performance of domestic models (especially self-owned brand models), especially the side impact performance, is generally poor, and the rational use of hot stamping parts can not only significantly improve the crash performance of the car body, reduce the weight of the car body, but also Effectively control the overall manufacturing cost of the body. Some domestic automakers of self-owned brands can not only view the new hot stamping technology from a strategic perspective, but also boldly adopt it in their new or improved models, and have achieved remarkable results. For a domestic model, after using hot stamping parts for the A and B reinforcement plates, its N-NCAP (foreign crash test) jumped from one star to three stars. It can be predicted that the new steel hot stamping technology will be more and more widely used in the automotive field, and the research on its related equipment and core technologies will also become a new research hotspot in the stamping industry.
In addition, the new steel hot stamping technology also has broad application prospects in the fields of agriculture and mining machinery, which can significantly improve the strength, hardness and wear resistance of related appliances.
