Co-extrusion at its Best

Co-extrusion is one of RAUMEDIC’s core extrusion capabilities and we are continuing to expand our co-extrusion portfolio.
RAUMEDIC has developed the processing capability to co-extrude a wide variety of metal wires and glass fibers within the tubing walls. RAUMEDIC can extrude copper, stainless steel, Nitinol, platinum alloys, nickel and silver plated wires within a wide variety of polymers, including Polyurethane, Silicone, Polypropylene, Polyethylene, Nylon and high performance resins (FEP, PEEK, PPSU, PEI and PTFE Moldflon™).


  • Within the medical device industry, many products need wires, cables and coils to be hand strung though multilumen tubing which can be very labor intensive. With the RAUMEDIC approach of co-extruding wires within the tubing walls, fabrication costs can be significantly reduced.
  • RAUMEDIC can offer co-extruded tubing where the wires are embedded or loose which can help with regards to kink resistance.
  • RAUMEDIC can offer a wide variety of wire/polymer combinations depending on the requirement. Our experience allows us to adapt to the application requirement.
  • Low scrap rates and the ability to meet tight tolerances
