725 Series Co-Extrusion Crosshead for Tray Cable


Customer Focus

With this project we partnered with the customer to
convert their production line from a Tandem line with 2
heads a distance apart to a Co-extrusion line with a
single head applying both layers in one operation


Low Volume Adjustable Center Co-Extrusion Crosshead (PVC over PVC)



  • Increased production output with shorter change over
  • Less scrap with single head setup
  • Improved quality via better adhesion between layers
    with melt adhering to melt rather than melt adhering to

    layers resulting in an enhanced quality part
