Tianjin Dingxin Membrane Breaks the Monopoly of Imported Technology and Receives CMC-CHINA Leading Enterprise Recognition: TRUSTECH Supports the Localization of High-End Hollow Fiber Membranes

Recently, Tianjin Dingxin Membrane Technology Co., Ltd. was recognized as a CMC-CHINA Leading Enterprise for its technological innovation and industrial application achievements in the field of high-performance membrane materials. As its technical partner in hollow fiber membrane spinnerets, TRUSTECH has long provided Tianjin Dingxin Membrane with high-precision spinneret technology support for membrane product development and industrialization, helping the company overcome technical barriers in critical manufacturing processes.

The development and production of high-performance membrane materials, particularly high-end hollow fiber membranes, require extremely high levels of precision in spinning equipment, fluid distribution uniformity, and product consistency. As a core component in the hollow fiber membrane spinning process, the spinneret directly affects the inner diameter, outer diameter, wall thickness, and spinning stability of membrane fibers through its structural design and manufacturing precision. Therefore, high-precision spinnerets have always been a critical technology for the industrialization of hollow fiber membranes.

During Tianjin Dingxin Membrane's technology development and product application, TRUSTECH provided targeted hollow fiber membrane spinneret solutions. The two companies conducted technical communication and optimization around key parameters such as spinneret flow-channel design, orifice precision, concentricity, and spinning stability, providing Dingxin Membrane with precision core-component support for the development and application of its membrane products.

TRUSTECH is a leading Chinese manufacturer of hollow fiber membrane spinning technology and equipment. The company has long been dedicated to the research, development, and manufacturing of hollow fiber membrane spinnerets, membrane spinning equipment, and related membrane manufacturing technologies. Its products are widely used in environmental water purification, gas separation, medical hemodialysis, and other fields.

TRUSTECH invests approximately 15% of its annual revenue in R&D, continuously improving its innovation chain covering materials, spinneret forming, spinning processes, and pilot-scale validation. The company has launched the fifth-generation FCT spinneret and continued to develop subsequent sixth- to ninth-generation technologies, accumulating more than 40 granted patents and other intellectual property rights. TRUSTECH is also one of the leading drafting organizations for the group standard Hollow Fiber Membrane Spinnerets, contributing to the development of industry technical specifications and product standardization.

Among its technologies, the FCT series hollow fiber membrane spinnerets feature innovative flow-channel and structural designs. By enabling more precise distribution and control of fluids such as polymer solutions and bore fluids, the FCT spinnerets provide critical support for stable control of hollow fiber membrane inner diameter, wall thickness, and membrane-forming consistency.

For different membrane materials and spinning processes, TRUSTECH can also provide corresponding spinneret solutions for a range of applications, including NIPS, TIPS, braided-tube reinforced membranes, as well as multi-bore and multi-core configurations.

At the same time, TRUSTECH continues to promote the evolution of membrane spinning technology from single-equipment manufacturing toward systematic technical services. With capabilities in multi-bore spinneret structural analysis, fluid simulation, and precision manufacturing, the company can provide customized designs based on customers' specific polymer materials, bore-fluid systems, and process parameters, supporting membrane manufacturers from laboratory research and development through to large-scale production.

For high-end membrane materials, moving from laboratory development to stable production requires not only innovation in the material system itself, but also high-precision equipment capable of implementing process parameters accurately and consistently. TRUSTECH believes that a spinneret is not simply a metal processing component, but an important technical interface connecting membrane materials, spinning processes, and final membrane performance. By precisely controlling fluid distribution during the spinning process, spinnerets can provide a more reliable foundation for membrane product consistency and large-scale manufacturing.

Tianjin Dingxin Membrane's recognition as a CMC-CHINA Leading Enterprise reflects its continued efforts in membrane technology innovation and industrial application. For TRUSTECH, its long-term technical cooperation with innovative membrane companies such as Dingxin Membrane further demonstrates the value of high-precision hollow fiber membrane spinnerets in advancing the industrialization of high-end domestic membrane materials.

Looking ahead, TRUSTECH will continue to focus on the research, development, and precision manufacturing of hollow fiber membrane spinnerets, working closely with membrane material companies, research institutions, and industry customers. Through high-precision spinneret technology, TRUSTECH aims to support the transition of new membrane materials from research and development to large-scale application, providing reliable core equipment support for membrane technology innovation in water treatment, biomedicine, gas separation, and other fields.
