Used Extruder

With a used extruder the cable industry applies plastics resp. polymeres like PVC, PE, PTFE, Teflon, Silicone, etc. to a single bare wire or a composite of already insulated conductors to create a cable. Important for the output of an extruder is the screw diameter and the length of the screw. While the diameter is given im mm, the length is mostly defined by a multiple of the diameter. For example a 60 mm 20 D extruders screw length is 1200 mm. A used extruders basically consists of a motor, a gear box, a barrel and the screw so principally used extruders are rather simple machines. Especially older machines are often constructed in such massive ways, that they practically never wear if they are maintained correctly.
Used extruders are often used to replace machines in existing extrusion lines, for example to increase the capacity, resp. speed of the line or add another coating in 1 prodcution run.
