Extrusion Puller

• Description:

  This puller is typically used with an extruder or other machine that produces plastic layered tubes or solids in various diameters.

• Application:

  Co-extruded plastic covering a base core or tube can be precisely sized using a hot die. A sub surface wire braid can be tested for exposed wires and any exposed areas cut out. Good product is then cut to a selected length.

• Design Highlights:

  The hot die is located between the two independent pinch drives. Each pinch drive is electronically geared to either a programmed speed or an input from an upstream size feedback (like a laserMike). The speed ratio between the two pinch drives can be adjusted through the touch-screen operator interface to control process slack. Exposed wires are detected using a high voltage tester. Air cylinders move the drive and process elements out of the way for easy setup.

• Benefit:

  This puller combines hot die resizing, insulation integrity testing and removal and cut-to-length features in a safe system that is easy to set up and adjust. Rejected product is minimized as the process is more-precisely controlled.
