Smoke can provide valuable information. An automotive supplier made this observation during the production of flexible tubes. This article describes why this is so and how it works more accurately with the help of a solution from ipf electronic. Flexible tubes are in demand for vehicle construction due to their small bending radii, as they make optimum use of the limited installation space inside the vehicle. An automotive supplier manufactures such tubes, e.g. for the distribution of hot and cold air in caravans. The flexible tubes are made of aluminum and kraft paper. To join these two materials firmly together, the tube is passed through an induction coil where it is warmed.
