Depending on the nylon material, nylon 6 and nylon 66 are common, i.e., fibers made of nylon 6 and nylon 66. The nylon is prepared by a melt spinning method, the melt spinning principle is that high polymer raw materials are fed into a screw extruder, conveyed to a heating area by a rotating screw, extruded and melted and conveyed to a metering pump. The metering pump controls and ensures that the polymer melt stably flows into the spinning box, the melt is filtered in the box and is pressed into the porous spinneret plate to spray out melt trickle, and cold air blown out by the temperature-adjusting bellows is rapidly condensed to form solidified silk bundle fibers. The nylon raw material extrusion melting device is the screw extruder, and the screw extruder is heated by the pressure and the shearing force generated by the rotation of the screw and the charging barrel, so that the nylon 6 and the nylon 66 can be sufficiently melted and uniformly mixed.

The machine head has the function of converting the plastic melt in rotary motion into parallel linear motion, so that the plastic is further plasticized uniformly, the melt is uniformly and stably introduced into the inlet die, necessary forming pressure is further given, the plastic is easy to form, and the obtained product is compact. The die is a channel with a certain cross-section shape, and the plastic melt is obtained into a required shape when flowing in the die, and is cooled and hardened by a shaping device and a cooling system outside the die to be shaped. The components of the machine head and the mouth die comprise a filter screen, a porous plate, a flow divider, a mold core, the mouth die, a machine neck and the like.
