Product Details

Product Description

AT227 Pilot Scale 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

★ Material Melting and Spinning Part

It consists of extruding part, extrusion measuring head, metering pump, spinning system and cross air-blowing device.

★ Measuring and Controlling Part

1. Data Monitor

* Real-time monitoring of material temperature and wall temperature.
* Air paths adopts full 304 stainless steel pipes, valves and pressure meter.
* Programmable temperature controller, PID automatic temperature control and programmable temperature controlling for three heating sections.
* PC remote control and interface display of extruding speed, hot roll speed, winding speed, metering pump speed, temperature and other necessary alarm and signal.

2. Over-limit Alarm
When over load, system will shut off the electricity.
* Over temperature alarm.
When over temperature, machine stops heating.
* Extruding pressure over-limit alarm
When extruding pressure beyond the limit, motor stops rotating.
* Metering pump rotation speed alarm
When metering pump rotation speed is away from the set value, auto alarm display.
