Haul-off and cutting units handle the final pulling and cutting stages of precision single-screw extrusion lines. Each unit uses servo-driven belts to grip the extruded tubing or profile and draw it forward at a controlled speed, while the PLC coordinates the belt haul-off and rotary cutter, so both operations remain in sync.

Features
  • Our haul-off and cutting units have safety guards at both the material infeed and discharge points, as well as a photoelectric sensor in the cutting section. If the enclosure is opened, the sensor stops the cutter immediately to protect the operator.
  • They are equipped with servo motor control to ensure the cutter matches different extrusion line speeds while maintaining accurate cut lengths.
  • The cutter mount can be moved forward, backward, left, or right, so operators can line it up quickly during setup and replace the cutting head when needed.
  • There is an alcohol reservoir built into the cutting unit which, after each cut, cleans and cools the blade in order to keep its temperature low, clear away the debris, and ensure that the finished products have a clean cut face even when working at high speeds.
  • As the haul-off and extruder controls work together, operators can adjust the extrusion speed from the haul-off panel or change the haul-off speed from the extruder panel. So, setup takes less time, and less raw material is wasted while the extrusion line is being adjusted.
  • The haul-off section's upper and lower belts each have their own servo motor and drive, so they can be controlled separately and pull the product (tubing or profiles) more steadily.
  • An RS485 communication port is reserved for connection to an outer-diameter or wall-thickness measurement system. The measurement data can then be used for closed-loop process control.
