Product details of the hollow fiber membrane manufacturers
Product Information
Each hollow fiber membrane manufacturers product from Shanghai Trustech Technology Development Co., Ltd. is the most professional and specific. The perfect product testing facilities and capable technology team ensure the performance of this product. The management system of Shanghai Trustech Technology Development Co., Ltd. has entered the standardization and scientific stage.
Product Overview
A NIPS hollow fiber membrane spinning equipment mainly includes four core sections: dope preparation, metering and extrusion, coagulation and forming, and post treatment and take up system. The hollow fiber emmbrane spinning machine performance and stability determine the quality and properties of the hollow fiber membrane. Leveraging 11 years of experience and R&D, Trustech has upgraded the SteadyiCore Ultra 2.0 Heating System, TitanMix Pro 4.0 Mixing System, PrimeGlider Pro 3.0 Automatic Pay-off, SmartCoil Elite 3.0 Automatic Winding, and StoutDrive 2.0 motor drive setup.
These Trustech technologies precisely control temperature, improve mixing uniformity and save time, automate take-up to reduce labor, and ensure constant speed pay-off to improve quality,thereby enhancing hollow fiber membrane spinning system stability and reliability, reducing setup time and production downtime, and increasing overall spinning efficiency by 11.4% compared with pre-upgrade levels.
