Lead

  As a key basic material supporting the development of modern manufacturing, engineering plastics are accelerating the replacement of traditional metal materials and reshaping the production pattern of multiple industries by virtue of their excellent mechanical properties, temperature resistance and lightweight advantages. Founded in 2004, Wuxi City Gangsheng Precision Plastics Co., Ltd. has been deeply involved in the field of engineering plastic modification and precision products for 20 years. It has promoted the performance upgrading of engineering plastics with continuous technological breakthroughs. It not only breaks down barriers to the import of high-end materials, but also becomes a "material engine" that empowers high-quality development in new energy, 3C electronics, medical devices and other fields.

  Technical challenge: solving the problem of performance upgrading of engineering plastics

  Breakthroughs in the performance of engineering plastics are the core key to determining their application boundaries. Since its inception, Gangsheng Precision has focused on the research and development of engineering plastic modification technology. It has invested a total of more than 50 million yuan to build a professional R & D center, established a technical team of more than 40 people led by doctors and senior engineers, and built a full-chain innovation system from basic formula design to industrial application.

  For high-end manufacturing

  Due to the strict demand for wear resistance and high temperature resistance of materials, the company's independently developed nano-reinforced modified engineering plastics have recently achieved mass production. Through the composite modification technology of carbon fiber and nanoparticle, the wear resistance of this material has increased by more than 67% compared with traditional engineering plastics., the friction coefficient has been reduced by 40%, and the ultimate bearing pressure has been increased by 30%, successfully filling the gap in the mass production of domestic high-end wear-resistant engineering plastics. In the field of new energy vehicles, the high-temperature modified PPS engineering plastics it has developed can withstand the continuous high temperature of 150 ° C in the engine compartment. It replaces metal materials in cooling fan drive gears, ECU connectors and other components, reducing the weight of individual components by 40%., helping to reduce the energy consumption of the vehicle by 8%, and related technologies have won 3 national invention patents.

  "Innovation in engineering plastics must not only break through performance limits, but also adapt to the actual needs of the industry." The technical director of Gangsheng Precision said that the team's annual R & D investment accounts for more than 8% of operating income, and has developed multiple series of modified engineering plastics such as polycarbonate (PC), polyetheretherketone (PEEK), and polyketone (POK). The tolerance control accuracy reaches ±0.01mm, reaching the international advanced level, which can meet the customized needs of different industries for material strength, corrosion resistance, and insulation.

  Scene implementation: Engineering plastics reshape the manufacturing ecosystem of multiple industries

  As performance continues to upgrade, engineering plastics are transforming from "auxiliary materials" to "core components", achieving breakthroughs in large-scale application in multiple fields, and Gangsheng Precision has become an important force in promoting this transformation.

  In the field of 3C electronics, micro-transmission components have extremely high requirements for material accuracy and stability. Gangsheng Precision adopts a micro-injection molding process and produces a micro-transmission gear using modified PC engineering plastics as raw material. The diameter is only 2-3 mm and the accuracy level reaches 6-8. It has been successfully applied to mainstream brand mobile phone auto-focus systems, enabling the focusing speed to be increased by 30%, equipment operating noise is reduced by 60%, and the annual supply exceeds 10 million pieces; In the field of medical devices, the medical-grade PEEK engineering plastic precision components developed by it have passed biocompatibility certification and have both chemical corrosion resistance and self-lubricating properties. They have been used in batches in dental treatment equipment, insulin pumps and other products. With the advantages of easy disinfection, shock absorption and noise reduction, they have been recognized by dozens of medical institutions across the country; In the field of drone manufacturing, the company uses an engineering plastic fuselage frame produced by a micro-foam injection molding process to achieve a 30% lightweight design while ensuring structural strength, providing key material support for improving drone endurance.

  Up to now, Gangsheng Precision has developed more than 120 customized engineering plastic formula products, with an annual production of 8000 tons of modified engineering plastics and more than 50 million pieces of precision plastic products. Its products cover electronic information, medical equipment, aerospace, new energy vehicles, etc. In many fields, it has not only become a core supplier to well-known companies such as Huawei and Mindray Medical, but also exported to more than 10 countries and regions such as Europe, America and Southeast Asia. Promote China's engineering plastics to enter the global market.

  Industry empowerment: Use material innovation to help "Made in China 2025"

  Currently, my country is accelerating the "Made in China 2025" strategy. The development of high-end equipment, new energy, new generation information technology and other industries has put forward higher requirements for the performance, quality and supply stability of engineering plastics. As a benchmark enterprise in the field of engineering plastics, Gangsheng Precision is providing key support for manufacturing upgrading through technological innovation and industrial collaboration.

  Relying on Wuxi City's policy support for the new materials industry, the "R & D and Application of High-Performance Fiber Reinforced Modified Plastics" project participated in by Gangsheng Precision has received funding from municipal key core technology research projects. The funds will be mainly used for laboratory upgrades and high-end talent introduction to further enhance the R & D strength of engineering plastics. At the same time, the "Environmentally Friendly Flame Retardant Modified Engineering Plastics" project that the company is working on has achieved halogen-free flame retardant through formula optimization. The combustion level reaches UL94V-0, and volatile organic compound (VOC) emissions are reduced by 50%. Green manufacturing provides sustainable material solutions.

  Looking to the future, Gangsheng Precision plans to invest 200 million yuan to build a new production base, introduce internationally advanced engineering plastic modification and testing equipment, and focus on expanding markets in emerging fields such as new energy vehicles and artificial intelligence equipment. "Engineering plastics are the 'invisible cornerstone' of manufacturing upgrading. Based on 20 years of technological accumulation, we will continue to promote breakthroughs in the performance of engineering plastics and the implementation of scenarios, and contribute more material power to 'Made in China 2025'." The person in charge of the company said.
