Hollow Fiber Membrane Casting Machine

A hollow‑fiber membrane casting (or spinning) machine is a device used to fabricate hollow fiber membranes — tubular polymer membranes with a hollow core — by extruding ("spinning") a polymer "dope" solution and internal (bore) fluid through a spinneret, followed by phase inversion (coagulation) and downstream processing. These membranes are used in ultrafiltration (UF), microfiltration (MF), gas separation, hemodialysis, membrane bioreactors, etc.
