AT225 Laboratory Melt Spinning Machine is a main key equipment in synthetic fiber production. This machine uses a high-temperature copper ring block to heat and melt the polymer sample, and extrudes the sample into a liquid trickle from a spinneret under the effect of inert gas (N₂) pressure to produce nascent fibers. It consists of a melting system, a spinning system and a winding system. Stable inert gas pressure system (gas source should be prepared by the user himself). Metal protective hood with an air leg. Colorful touch screen, real-time display of temperature and air pressure in the cylinder. Be able to independently set and control the temperature of each heating zone. Three heating zones with copper ring blocks for heating. Insulation plate under the feed cylinder to block the spinneret hole for rapid heating. Maximum temperature up to 350℃. Cooling fan with adjustable speed.
