Hollow Fiber Spinneret
HFSM is one of spinnerette manufacturers, design and manufacture high precise hollow fiber spinneret for hollow fiber membranes in large scale production.
What is Hollow Fiber Spinneret?
Hollow fiber spinneret is a key component on hollow fiber spinning machine. It is mainly used to convert spinning solution or melt into fiber. Its shape, material and classification vary depending on the spinning method.
In chemical fiber manufacturing, hollow fiber spinneret is a precision component that extrude solution or melt through micropores to form fibers. It has various shapes, such as hat shape, disc shape, etc., and the material selection depends on the type of spinning process. For example, melt spinning spinnerets require high temperature resistant stainless steel, and wet spinning uses corrosion-resistant metals. In addition to industrial use, the term also refers to insect silk-producing organs or open source projects, but the two are not directly related to hollow fiber spinning machine parts.
