2. Technological Innovation and R&D Capability
Patent achievements: We have obtained more than 30 national invention patents and utility model patents, covering key areas such as PC/ABS modification formulas, flame retardant technology, equipment modification, and toughening and reinforcement.
School-enterprise cooperation and professional team: In 2017, we established a cooperation with South China University of Technology to jointly carry out research and application development of PC modification technology, accelerating the transformation of scientific and technological achievements. The R&D team is led by two engineers with over 20 years of experience in PC modification, with full online guidance from professors of materials science at South China University of Technology. Several doctoral students in polymer materials and engineering participate in synthesis and research and development. The company continues to seek long-term talent exchange and cooperation with top universities and research institutions in the PC industry.
Breakthrough in Halogen-Free Flame Retardant Technology: We have independently developed halogen-free flame retardant technology, achieving dual optimization of environmental protection and cost. Our product costs 25% to 30% less than imported PC/ABS flame retardant materials, yet maintains excellent performance. This technology effectively promotes domestic substitution and provides customers with cost-effective options.
Collaborative development of additives: We collaborate with professional manufacturers of flame retardants, toughening agents, and phase solvents to develop specialized additives for PC modifications. This ensures that the key physical properties of the materials far exceed those of similar products, providing safety guarantees for special scenarios and addressing customers' practical pain points.
R&D facilities: Equipped with independent material R&D laboratories, production line quality testing laboratories, and CNAS full-system material certification testing laboratories (third-party cooperation platform), we have built a full-process R&D platform from formula development to finished product verification.
3. Production and Quality Assurance
Independent workshop color separation production: Four independent workshops are established to strictly distinguish the production of black, natural, white, and colored plastic granules, eliminating cross-contamination. The product color difference is stably controlled within the international standard of AE≤0.5.
Full-process quality control: From carefully selecting high-quality raw materials to testing, sample testing, pilot testing, mass production line testing, warehousing testing, and shipment testing, we rigorously inspect at every stage, with the ultimate goal of achieving a 0% return rate, ensuring that every batch of materials we transport and produce fully meets customer standards.
Intelligent production: intelligent weightless scale + fully automated material suction and homogenization mixing + automated packaging, with the entire process precisely controlled by high-tech equipment to ensure consistent and stable product quality.
7S on-site management and traceability: Adopt the 7S on-site management system to maintain a clean and orderly production environment, establish a traceability system for each batch, quickly locate and solve abnormal issues, and achieve refined and efficient production.
Modern Smart Manufacturing Base: Equipped with a 5000+ square meter production base and six fully automated production lines, it boasts an annual production capacity exceeding 20,000 tons. The intelligent production lines operate 24 hours a day, achieving a maximum daily production capacity of over 100 tons. It supports rapid delivery of orders within 24 hours and offers full digital management and tracking throughout the process.
4. Authoritative qualification certification
It has been successively rated as a national high-tech enterprise and a provincial innovative enterprise. It has obtained ISO9001, IATF16949 quality management system certification, ISO14001 environmental system certification, ISO45001 occupational health and safety management system certification, AAA-level enterprise credit rating certification, and other authoritative certifications both domestically and internationally.
5. Products and Applications
Flame-retardant PC/ABS for new energy applications: The produced flame-retardant PC/ABS material meets the UL94V-0 level of flame retardancy, featuring high strength, high temperature resistance, low smoke, and non-toxicity. It provides comprehensive safety protection for new energy vehicles, aiding in weight reduction and energy consumption reduction. Typical applications:
New energy vehicle battery housing: flame retardant and impact resistant, ensuring the safety of the battery pack.
Instrument panel and central control panel: High gloss, scratch-resistant, with a balance between aesthetics and fire resistance.
Exterior door handles and interior trims: resistant to UV aging, maintaining their color and shape even after long-term use.
Customized Services: Flexibly adjust parameters such as color, hardness, and flame retardant grade according to customer needs, providing precisely matched PC-based materials for products such as home appliance casings, energy storage power supply casings, and automotive electronic components, meeting personalized needs in different scenarios.
