Since its establishment, Firstunion Group has firmly built its own atomization system. According to the "3+N+1" model, it implements the R&D layout for all aspects of R&D investment in the field of electronic atomization, and takes the three research institutes of Great Health life science, basic science and product platform as the core for the underlying research of forward-looking technologies. Coordinate the cooperation and function of multiple departments such as product application research and development, industrial design, intellectual property, standard compliance, etc., and set up several top R&D laboratories overseas in Toronto, Canada, Los Angeles, United States, Swansea, UK, etc., to complete the development and verification of products. In addition, the R&D results are repeatedly optimized according to the sensory experience of customers and users, so as to achieve a perfect cycle of underlying technology + product application. Now we have developed four technology platforms of "nicotine atomization, heating without combustion, medical atomization and functional substance atomization". Dozens of products are under research, covering all atomization products in the big health field such as change-over, disposable, open, HNB, CBD and functional substitutes.
