Trustech Awarded Invention Patent for "Modular Multi Orifice Hollow Fiber Spinneret Plate"

In the field of hollow fiber membrane spinneret heads, Trustech has received another piece of good news: its independently developed "Modular Multi Orifice Hollow Fiber Membrane Spinneret Head" has been granted a national invention patent (Authorization Announcement No. CN104894663B). With its digitized, modular, and flexible design innovations, this patented technology injects strong momentum into the industry's development.

As a leading manufacturer of hollow fiber membrane spinneret plates and membrane spinning equipment, Trustech has been deeply engaged in this field for many years and has filed more than 40 patent applications to date. The birth of this patented technology is powerful proof of the company's continuous innovation. The patented product comprises a flow guiding module and a spinneret module; multiple spinneret modules are mounted to a single flow guiding module by screws. This distinctive split design addresses numerous pain points of traditional spinneret heads.

Conventional single orifice spinneret heads are extremely inefficient, while multi orifice heads face issues such as complex structures, difficult maintenance, and limited scalability in the number of orifices. This modular spinneret head achieves three major breakthroughs: in terms of digitization, it can expand the number of spinneret orifices without increasing production difficulty, greatly improving production efficiency; the modular design lowers manufacturing and assembly difficulty, and individual modules can be maintained and replaced independently, saving substantial time and cost; its flexible characteristics enable a single spinneret head to produce multiple product specifications simultaneously, precisely meeting different customer needs.

This patented technology aligns closely with Trustech's technological upgrade roadmap. As the developer of spinneret plate technologies from the 4th to the 9th generation, the company has built deep capabilities in ultra precision machining: machining accuracy up to 0.002 mm, surface roughness Ra 0.2-0.4, concentricity 0.003 mm, and support for multi orifice expansion. In wet process, dry jet wet spinning, environmental water purification, medical hemodialysis membranes, and gas separation membranes, it enables scaled spinning at 16, 20, 32, 128, and 1,024 orifices, greatly boosting production efficiency. This patent is a concentrated embodiment of the company's technical strength. At present, its products are exported to 39 countries and regions, serving 634 customers.

The acquisition of this patent further consolidates the company's leading position in the industry. As the lead drafting organization of the group standard "Hollow Fiber Membrane Spinneret Plate," Trustech has consistently driven industry progress through independent innovation. Such patent achievements—combining technological depth with application value—not only demonstrate the company's R&D prowess, but also provide strong support for the high quality development of the industry.
