New extrusion head designed for tray cable
Guill Tool has introduced Series 725, a co-extrusion crosshead design for tray cable applications. With an all stainless steel construction, Series 725 offers machine builders and end users advantages including the patented Guill Seal Right system of self-aligning tapered deflector and body design.
Series 725 was developed by Guill engineering, in partnership with a customer, to convert a production line from a tandem line with two heads a distance apart into a co-extrusion line with a single head applying both layers of PVC in a single operation.
Other end-user benefits of the new co-extrusion crosshead include a shorter changeover time; less scrap owing to the single head set-up; improved product quality from the increased adhesion between layers, as melt adheres to melt rather than extrudate; and the inner layer is not exposed to the environment, which prevents contaminates between the layers.
Additional features of the new crosshead include multi-port spiral flow, easy disassembly and restart, positive seals for leak elimination, the patented Guill Feather Touch concentricity adjustment, a vacuum port and the ability to accept two extruders from the same side via the heated manifold assembly.
The maximum through-core is 1.75" and maximum die ID is 2". The first layer is fixed and the second is adjustable, and the crosshead can be adapted to all extruder brands. Series 725 is supplied with a tool kit and detailed operator's instruction manual.
