Mobile welding and repairing equipment for reinforced and non-reinforced thermoplastics has induction heating for the polymer and a feed roll pair at a distance from the induction coil

摘要

The polymer matrix is heated by induction using a 20 kHz-10 MHz electromagnetic field. Welding force is applied continuously under pneumatic loading through a heated pair of pressure rolls(3) at a distance from the induction coil(1).
