Infrared heating for adhesives on decorative trims for vehicle doors

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, it used a purpose-built adhesive, which requires the addition of reactivation heat after it has been applied, to ensure optimum adhesion.
