Product Description
AT227 Continuous Melt Spinning Machine 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.
features
Melt spinning part
It consists of extruding part, extrusion measuring head, melt pump, spinning system and cross air blow device.
1. Extruding part
