Weihai Jinhong Group Co., Ltd. is situated in the Weihai Lingang Economic and Technical Development Zone. Originally established in 1986 as the Wendeng County Chemical Materials Factory, the company was restructured in March 2009 to become Weihai Jinhong Group Co., Ltd.
Jinhong Group is a diversified, modern enterprise conglomerate with business segments spanning basic chemical raw materials, fine chemicals, product manufacturing, new materials, new energy, battery testing, bridge inspection, engine blade structural analysis, aerospace, the nuclear industry, electric power, and the defense sector—thereby forming a comprehensive industrial layout. The Group oversees eight holding subsidiaries, including Jinhong Polymer, Jinhesi Chemical, Haoran Specialty Plastics, Jinyu Environmental Protection, Jinhong Piping, Chenyuan Molecular New Materials, Weidinghang Testing Equipment, and Hongtai Electronics. Each of these segments shines like a brilliant gem, radiating across the global stage through their exceptional innovative capabilities, robust technical strength, and leading product quality.
Upholding the philosophy of "Safety as the Foundation, Green Initiatives as the Wings, and Talent as the Core," Jinhong Group actively implements the central concept of "Green Intelligent Manufacturing." By comprehensively restructuring its corporate management systems and mechanisms, the Group has laid a solid foundation for standardized operations and internationalization.
In the face of the global wave of green and low-carbon transformation, Jinhong Group remains steadfast in its commitment to a path of ecological priority and green development. The Group has established a digital empowerment platform built upon an Industrial Internet architecture. This initiative involved a total investment exceeding 30 million RMB and features an intelligent central control room spanning approximately 900 square meters. This facility integrates five major functional modules—the DCS Central Control System, SIS Safety Instrumentation System, GDS Combustible/Toxic Gas Alarm System, Fire Alarm System, and Video Surveillance—thereby providing a benchmark solution for the green upgrading of the traditional chemical industry.
Deeply rooted in the philosophy that "talent is the foundation," Jinhong Group has established a "dual-track" career development system, an empowering talent cultivation mechanism, and a framework for incentives and value sharing. To date, the Group has cultivated a technical workforce comprising 185 engineering professionals, including 17 with senior professional titles, 40 with intermediate titles, 15 holding doctoral degrees, and 12 holding master's degrees. The Group currently possesses two national-level research platforms—a National Enterprise Technology Center and a National Post-doctoral Research Workstation—as well as ten provincial-level research platforms, including a Provincial Enterprise Technology Center for Dendritic and Hyperbranched Polymers, a Provincial Engineering Technology Research Center for Dendritic and Hyperbranched Polymers, an Engineering Laboratory for Polysulfone Materials, and a Provincial Demonstration Engineering Technology Research Center for Plastics. Jinhong Group remains consistently dedicated to cultivating a fertile environment for talent, ensuring that the realization of individual talent value resonates in perfect harmony with the growth and development of the enterprise. As a benchmark for innovation in China, Jinhong Group has established a core technology matrix characterized by "two 'firsts,' one 'unique,' and one 'breakthrough'." This matrix encompasses: Asia’s first R&D and industrialization initiative for fourth-generation dendritic polymer materials; China’s first mass-produced medical-grade polyethersulfone (PESU)—including materials for hemodialysis membranes—as well as industry-leading polyphenylsulfone (PPSU) and polyarylethersulfone tougheners for carbon fiber composites that rival international brands; China’s sole producer of acrylamide-based polymers utilizing a water-medium dispersion method; infrared thermal wave imaging equipment for non-destructive testing—a technology that broke through international blockades and filled a critical domestic gap; and a range of proprietary products developed via aqueous suspension methods, such as chlorinated polyethylene (CPE), high-purity biphenol, and various specialized grades like K-20P and K-418, alongside leading domestic products such as ACR and MBS. Whether filling domestic voids, breaking international monopolies, or standing at the forefront of global technology, these diverse products collectively represent China’s intelligent manufacturing sector’s compelling answer to the call of the modern era as it expands its global reach. To date, Jinhong Group has been granted 50 authorized invention patents, 59 utility model patents, 16 software copyrights, and 3 design patents. Furthermore, the Group has participated in the formulation or revision of five national and industry standards, and has successfully completed over 50 technology-related projects commissioned by national, provincial, and municipal government agencies.
Standing at a new historical juncture, Jinhong Group upholds an enterprise spirit defined by "Innovation, Pragmatism, Diligence, and Enterprise." The Group is dedicated to establishing industry benchmarks for safety, utilizing "green and intelligent manufacturing" to reshape the industrial ecosystem, and—with an open and inclusive mindset—gathering talent from across the globe. By providing customers with high-quality services and high-value products, Jinhong Group aims to infuse "Jinhong Wisdom" into the sustainable development of society.
Resonating with the pulse of the times and walking hand-in-hand with its partners, Jinhong Group is currently writing a new chapter in the high-quality development of "Made in China"—driven by cutting-edge technology and a profound sense of corporate responsibility.
