Fiber Melt Spinning System

AT227 Fiber Melt Spinning System is a main key equipment in synthetic fibre production. This machine uses high temperature ceramic to heat and melt the polymer sample, and extrude the sample to be liquid trickle from a spinneret under the effect of inert gas pressure, then nascent fibers form under the effect of air cooling. It is specially designed for small batch production test to simulate the field production.
