Duplex extruders are used for tyre tread and other related rubber semi-finished products that need two compounds to be combined in one extrusion process. For automatic tyre production, this means better control of tread shape and a more stable bond between the two compounds.

Features
  • The built-in co-extrusion setup helps the tread come out with a more accurate size and a tighter overall structure.
  • Different configurations are available, including dual-cold feed extruders and cold-hot feed extruders. Depending on the setup, the extruder can be equipped with a hard gear reducer, a hydraulic die head, and systems for temperature and pressure monitoring.
  • Temperature is controlled automatically through a warm water circulation system, and DC speed control helps the extruder run more steadily.
  • In dual-hot configurations, a mechanical die head is used. AC or DC speed control can be selected according to actual production requirements.
  • Deplex extruder can be designed in different configurations to match specific product and process needs.
