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