Impact Print-Type Hot Embossing Process Technology

Abstract

In this study, we propose a new hot embossing technology called impact print-type (or simply, impact-type) hot embossing process. Our process is based on the concept of a dot or line printer, in that it involves forming a fine pattern by applying force on a heated substrate using a fine probe or fine-shaped printing head. We developed a prototype and conducted experiments using it to verify the efficacy of our method in which an electromechanical impact actuator is used to create the necessary force. We believe that our study makes a significant contribution to the literature because, unlike conventional embossing processes, our method can not only intricately create fine structures, but can do so in real time, without incurring high replacement costs for creating embossing stamps as in conventional methods when a different design is required. © 2018 WILEY-VCH Verlag GmbH & Co.
