Micro-process technologies for medical market
- Fine tension regulation system have been developed and installed at each step of the cable production process (wire insulation, assembling, shielding, jacketing) to avoid any thin wires elongation or deformation and to provide consistent geometry. “We can control the pull force over wires in line down to several grams, that makes possible the stranding of AWG52 conductors or the shielding by 15 microns wires diameter ” precise Thierry Malvache, Nexans medical product manager.
- New jacketing technology using micro-extruder with material output less than 1g/min has been developed. “This process enable us to reduce our cable outer jacket thickness down to 15 microns which is prominent for space saving design” said Thierry Malvache.
- Non destructive and contact free measurement system have been installed in production lines in order to detect micro defects (down to 5 microns size) and to control, along 100% cable length, the dimensions, the geometry and the dielectric strength of insulation with perfect reliability.
