Rosendahl extrusion equipment

Rosendahl, a global supplier for turnkey extrusion equipment, provide a wide range of equipment for automotive wire applications, including: Single core extrusion lines with quick colour change systems; battery cable extrusion lines; multi-conductor cable jacketing lines and POF cable jacketing lines. Single core extrusion lines : The production programme of Rosendahl, includes standard line types equipped with two extruders, as well as with quick colour change lines with three or four extruders. The auxiliary extruders are available as vertical machines, respectively, as horizontal machines. The operating range of a typical automotive wire extrusion line, covers the cross sectional range of 0.22 to 7mm². Rocomat quick colour change system : The unique and patented Rocomat quick colour change system features a rotating shaft integrated into the crosshead. This design assures a maximum compactness.

Additionally, the Rocomat is also capable of realising the by- pass function of all extruders connected to the same system. Scrap marker : Rosendahl lines can be equipped with a special scrap marker. This module provokes spark faults, which trace quality errors, such as welding points. Cooling troughs : By using brake systems for deflection pulleys in the multi-pass cooling trough, thedowntimes after wire breaks can be reduced significantly. The highly efficient cable dryers ensure a proper function, even at top line speeds. Take-up systems : Rosendahl’s single core extrusion lines are available with different take- up systems, such as double spoolers, barrel coilers and ring coilers.
