In Feicheng, a “grid” embodying technological power is writing a legendary chapter in the history of “Made in China.” Feicheng Lianyi Engineering Plastics Co., Ltd., with its outstanding achievements in the field of glass fiber composite engineering materials, has won the national-level manufacturing single-item champion title, becoming an industry benchmark.
“Currently, our company’s products are exported to more than 20 countries and regions, and our global market share has ranked first for three consecutive years,” said Zhang Feng, Deputy General Manager of Feicheng Lianyi Engineering Plastics Co., Ltd.
Faced with foreign technological monopolies, the R&D team of Lianyi Engineering Plastics Co., Ltd. demonstrated extraordinary courage and perseverance. They spent ten years diligently researching and developing, finally overcoming the most challenging issues by pioneering a “flexible dual-resistance” coating material, successfully solving bottleneck problems such as differences in longitudinal and transverse strength and poor wear resistance. In the medium-temperature extrusion impregnation process, this technology allows glass fiber bundles to achieve “deep coating,” resulting in a qualitative leap in product performance.
“A radial breaking strength of 300KN/m, and the ability to maintain 93% performance retention even in extreme environments ranging from -40℃ to 170℃—these figures directly surpass those of the German Hauske Group,” said Zhao Xiuwei, Deputy Director of the R&D Department of Feicheng Lianyi Engineering Plastics Co., Ltd. Moreover, the company transformed imported German equipment into “Made in China” equipment, reducing energy consumption by 27% while increasing production efficiency by 30%, breaking the foreign technological blockade with concrete actions.
From follower to leader, 110 patents have built a technological moat for the company, and three provincial-level innovation platforms have forged a formidable R&D team. When the technological barriers of foreign companies were broken down, Feicheng Lianyi proved with its strength that the secret to its single-item championship lies not only in the resilience of every fiberglass strand, but also in the journey of “strengthening the foundation and supplementing the supply chain” in the Chinese manufacturing industry.
Today, Feicheng Lianyi Engineering Plastics Co., Ltd. is not content with its current achievements but actively adapts to market changes and embarks on a new transformation. In the past, the company focused more on the performance and sales of single products, making it difficult to meet the personalized needs of customers. To address this, the company established its own project innovation team, investing 4.2% of its annual revenue in R&D, comprehensively improving equipment, products, and services, and creating a full-industry chain service model integrating R&D design, testing and inspection, technical consulting, and customer training. The recent order for composite multi-directional performance optimized grid products is the first result of this transformation.
Through the transformation towards system integration and service integration, the company has opened up new development opportunities. In the production workshop, digital equipment such as laser automatic cutting machines and intelligent warp knitting production lines operate efficiently according to preset programs. The “Research and Application of Digital Design Methods for Geogrids” project utilizes an industrial internet platform to establish a new service-oriented manufacturing model covering the entire product lifecycle. This promotes deep integration of product manufacturing with R&D, marketing, and supply chain management, filling gaps in related technologies both domestically and internationally.
Currently, the company has two domestically advanced chopped strand mat production lines, with a maximum width of 3.4 meters and an annual output of 13,000 tons. It has accumulated 57 authorized patents, participated in the formulation of 7 national standards and 1 industry standard, and its independently developed bidirectional warp-knitted polyester geogrid and fiberglass bidirectional composite geogrid technologies have reached leading levels in China.
As a leading enterprise in Feicheng City’s high-performance fiber and composite materials characteristic industrial cluster, a national high-tech enterprise, and a national manufacturing single-item champion enterprise, Feicheng Lianyi Engineering Plastics Co., Ltd. holds a leading position in the domestic industry thanks to its strong technical strength, innovation capabilities, and excellent service level. Its production capacity, market share, and brand influence are all ranked first, leading the industry forward and continuing to write a glorious chapter in the history of Chinese manufacturing.
