A cable pellet production process

The present invention discloses a cable pellet production process, comprising the steps of: mixing the plurality of initial materials are mixed to form a mixture; hot melt, the hot-melt mixture to form a melt; extruding the the melt extruded from the discharge port of the mold, strip-shaped semifinished product are formed; cooling, water cooling of the semi-finished product cooling process; primary drying, the semi-finished product for the primary drying the water-cooled cooling; pelletizing , after drying the semi-finished product into pellets; humidifying, the humidity treatment pellets, dried a second time, after humidification of the pellet dried a second time. Extrusion process proposed by the present invention obtained thickness of the insulating layer of the cable uniformly, and close to the predetermined thickness of the insulating layer, thereby improving the quality of the cable.
