Norafin Industries GmbH (Mildenau, Germany) exhibited at JEC Americas 2014 its heatable nonwoven materials made of conductive fibers. Through a joint R&D project with German partners Latzsch GmbH Kunststoffverarbeitung (Thierbach), Kompetenzzentrum Stukturleichtbau e.V. (Chemnitz) and IMM Gruppe (Mittweida), Norafin has demonstrated heated tooling made with its conductive nonwovens using 48V through-voltage that reportedly can maintain temperatures up to 180°C/356°F with a tolerance of ±2°C across the mold surface. Other benefits include heating time of less than one minute, drapability that allows complex shapes and easy integration into tool fabrication. Norafin claims this technology can reduce overall curing cycle times.
