Polymer and Wire Co-Extrusion

Polymer and Wire Coextrusion

Wire Coating and Wire Inlay: This is How Your Tubing Can Become a Data Transmitter

Medical engineering is facing increasingly difficult challenges. The main issue hereby: procedures that are patient-friendly and ensure fast recovery by usage of ultra-small components. RAUMEDIC is contributing to that development and is also your competent partner for the application of co-extruded wires in medical engineering.

We combine, for example, nitinol, platinum alloys or copper and stainless steel wires with various polymers. We are also able to realize coatings made of high temperature thermoplastics, such as PEEK, FEP and thermoplastic PTFE, tailored to your particular requirements.

Coated Micro Cables and Wires

  • Ultra thin layer thicknesses starting from 0.01 mm (0.0004″)
  • Wire diameters from 0.025 mm to 1.5 mm (0.001″ to 0.059″)
  • Dimensions and materials are fully customizable

Exemplary Functions

  • Guide wires
  • Micro cables, e.g. for forwarding signals in catheters
  • Corrosion protection for wires
  • Pacemaker electrodes
  • Liner for the extrusion of thin walled tubing

Wire Inlay

  • Possibility to fully embed several wires in the tubing wall
  • Wall thickness from 0.5 mm (0.02″)
  • Wire diameter from 0.06 mm to 1 mm (0.002″ to 0.039″) 
  • Dimensions and materials are fully customizable

Exemplary Application Areas & Functions

  • Malleable suction cannulas
  • Nerve stimulation
  • Steerable endoscope
  • Signal forwarding in catheters with measuring functions


In collaboration with you we develop a product tailored to your requirements.
