The Vital Role of Spinnerets in Membrane Manufacturing Systems

One of the key technologies integrated into our hollow fiber membrane spinning systems is our advanced spinneret nozzles for membrane manufacturing. MEMS has dedicated two decades to perfecting nozzle technology, resulting in world-class, cost-effective spinnerets of various specifications. Unlike the conventional two-stage process of creating a composite membrane, our nozzles can create one simultaneously while spinning, saving time and resources. The performance of MEMS nozzles matches that of leading global nozzle companies' products, while offering offering half the price.

What is a spinneret? in membrane manufacturing

A single spinneret (nozzle) is an essential tool in membrane manufacturing, controlling the flow of polymer solutions or melts through fine holes to create thin filaments deposited onto a substrate. Its design influences membrane properties, where researchers can explore advanced features like adjustable inside/outer diameter sizes for precise customization.
