HIT Devices Ltd., developed the HDR-0670 heating head. The structural difference between this heating head and the existing products is basically the contact surface with the media is not the heat-generating side of the substrate. The media contacting surface is made of ceramic which has excellent anti-abrasion capability and it can be treated according to the application purposes for various media. Also, it utilizes the thermal energy efficiently by employing the structure which transfers the generated heat to the media effectively by observing the surface temperature drop at the time of media contact. It is possible to heat the necessary part of the media with the proper temperature for the determined amount of time easily by the combination between the heating head and temperature control circuit which monitors and measures the amount of heat transferred on real-time. The heat transfer between the heating head and media when the media moves at high rate was investigated. This report is the result of study of diverse and efficient usage methods including the improvement and kaizen of explicit or hidden problems by visualizing (mieruka) and analyzing the various thermal characteristics.
