Thermal Imaging Camera for Process Control

Thermal imaging cameras for process control
Assuring quality control, deciding if a product is 100% to specifcations, whether it is “good or bad” is

just one step. Thermal imaging cameras can help to do this and more. Often thermal imaging cameras provide valuable data about the production process. Production engineers can use these data to improve the entire production process.

Automotive industry
Cars need to be light and strong. To achieve both of these goals, modern car panels are made of a combination of a metal layer on top and a structural adhesive layer underneath. These layers are glued together using induction. The temperature has to be exactly right for the adhesion to work properly. To ensure that the adhesion goes smoothly, FLIR thermal imaging cameras can provide automatic feedback during the process.

Glue bead verifcation
Clear glue or black glue applied to a black background is very diffcult for a visible light camera to see and measure. FLIR automation cameras, however, can easily determine whether the glue bead has been applied properly, has gaps, and even if it is within the allowable temperature limits.

Paper moisture characterization
Paper quality can be affected by variations in moisture. FLIR thermal automation cameras pick up the temperature differences caused by moisture variations to help paper mills keep their processes in control.
