With the surging demand for high-efficiency components in fields such as thermal management of new energy vehicles and heat dissipation of industrial equipment, Ningbo Zhimei
Plastic products Co., LTD. (hereinafter referred to as "Ningbo Zhimei") has made a strong breakthrough with its high-efficiency plastic fan blade series products featuring a multi-material system. This core component, which integrates materials science and fluid mechanics, covers all application scenarios including home appliances, automobiles, and new energy. It not only validates the development direction of China's plastic industry towards "lightweight and high performance", but also seizes the initiative in the global plastic fan market worth 8.6 billion US dollars by 2025.
I. Material Revolution: 3D Material Matrix Overcomes Extreme Scene Challenges
Ningbo Zhimei, with modified engineering plastics as the core, has built a material system suitable for diverse scenarios, solving the industry pain points of traditional wind blades such as "insufficient strength and narrow adaptability". Its star products are made of three core materials
The reinforced nylon type is added with 30% glass fiber, achieving an impact strength of 12kJ/m². It can withstand the centrifugal impact during high-speed rotation and has become a core component of the thermal management system in new energy vehicles. Compared with traditional metal fans, its weight is reduced by more than 60%, significantly lowering the operating load of the equipment.
The weather-resistant PP model has passed the extreme temperature test ranging from -40 ℃ to 100℃. It can be used for a long time in outdoor industrial ventilation equipment without becoming brittle or deformed, and is suitable for the high-temperature working conditions in Southeast Asia and the cold environment in the north.
The flame-retardant ABS model complies with UL94 V0 standard and can self-extinguish when exposed to open flames. It is specially designed for high-risk scenarios such as home appliances and charging piles. At the same time, it has passed the RoHS environmental protection certification. The feature of no heavy metal residue makes it suitable for food-grade ventilation equipment.
"Materials are the foundation of wind blade performance." " The technical director of Ningbo Zhimei stated that the company, relying on its own mold manufacturing capabilities, has achieved vertical integration of "material modification - mold development - finished injection molding", shortening the material research and development cycle by 40%. This advantage enables the company to maintain a gross profit margin of over 22% even under the industry pressure of an 18% increase in engineering plastic costs in 2025.
Ii.full-scenario coverage: Precise adaptation from automotive thermal management to home appliance heat dissipation
As a core component of ventilation and heat dissipation equipment, Ningbo Zhimei plastic fan blades, with their "one device, multiple functions" design logic, achieve full-field penetration. In the automotive field, its ventilation impeller is optimized through fluid mechanics design. The blade Angle adaptively adjusts with the rotational speed, and the heat dissipation efficiency is 15% higher than that of traditional products. It has become the preferred choice for the thermal management systems of many new energy vehicle manufacturers. In the home appliance scenario, the lightweight structure reduces motor energy consumption, meeting the silent requirements of air conditioners, refrigerators, etc., with noise levels controlled within 35 decibels. In the industrial and new energy sectors, its corrosion-resistant material and high strength make it suitable for use in energy storage power stations and data center cooling systems. After being applied in a certain data center, its annual power consumption decreased by 12%.
This all-scenario adaptation capability precisely meets market demands. Data from 2025 shows that emerging fields such as new energy vehicles and data centers have driven the demand growth rate of plastic fans to exceed 20%. Ningbo Zhimei, with its multi-category layout, has received bulk orders from the Yangtze River Delta and the Pearl River Delta, among which automotive fan blades account for 38%.
Iii. Industry Implications: The "Specialized, Refined, Distinctive and Innovative" Breakthrough Path for Small and Medium-sized Plastic Enterprises
Breakthrough Path for Small and Medium-sized Plastic Enterprises
Under the pattern of "large-scale dispersion and small-scale concentration" in the plastic fan industry, Ningbo Zhimei's breakthrough provides a referenceable sample for small and medium-sized enterprises. Established in 2016, Zhimei Plastic Industry avoids the price war in the low-end market and focuses on material modification and precision manufacturing. It has built a barrier through "in-depth cultivation in niche fields + vertical integration of technology" - its independent mold research and development capability enables product adaptation accuracy to reach 0.01mm, far exceeding the industry average. This "small but exquisite" positioning differentiates it from leading enterprises in competition.
At present, Ningbo Zhimei is promoting the research and development of bio-based plastic fan blades and plans to launch a series of products made of recyclable materials within this year, further aligning with the EU's circular economy standards and China's "dual carbon" goals. This small but exquisite plastic component is becoming a microcosm of the high-quality development of China's plastic industry.
