‘Infrared heat activates adhesives on decorative trims’ - .PDF file.

An infrared system from Heraeus Noblelight is helping R-Tek to achieve perfect adhesion of decorative trims on the inside of motor vehicle door panels. The plastic decorative trims are normally fixed to the panels on a production line by spraying the inside of the panel with an adhesive and then applying the trim. However, when R-Tek started to experience problems with the adhesion, it was soon established that the prime cause of the problem was the fact that the adhesive often tended to part-cure between the spraying of the panels and the application of the trims. To solve this, the company used a purpose-built adhesive, which requires the addition of reactivation heat after it has been applied, to ensure optimum adhesion. After discounting hot air blowers as a means of providing the reactivation heat, because of their high power consumption and lack of controllability, it was decided to investigate the potential of infrared heating systems for this particular application. Trials proved so successful that a complete infrared system, using carbon emitter technology, was installed at R-Tek.
