Effect of Ultrasonic Vibration on Increasing Embossing Speed during Hot Glass Embossing Process
Applied Mechanics and Materials, 2019Nowadays, microstructures have an important role in optical products as well as in optical systems. Beside machining methods, hot glass embossing is recently a novel technology to manufacture microstructures in optical components with high quality and low cost. Especially, this technology has been assisted efficiently by ultrasonic vibration.

Polymer circuit boards fabricated by ultrasonic hot embossing
Journal of Micromechanics and Microengineering, 2013In this paper, a novel polymer circuit board fabricated by ultrasonic hot embossing is presented. Conductive paths are generated by ultrasonically embossing interruptions into a continuous metal layer coated onto a plastic substrate, and all electronic components are mounted onto the board in a single ultrasonic process step.

Hot embossing precise structure onto plastic plates by ultrasonic vibration
Polymer Engineering and Science, 2005AbstractHot embossing achieves excellent performance in replicating precise features onto large plastic plates. It has become a popular approach because microstructures in master molds can now be easily made using Lithographie GaVanoformung Abformung (LIGA) and micro‐electro‐mechanical‐system (MEMS) technologies.

Fabrication of Molded Interconnection Devices by Ultrasonic Hot Embossing on Thin Polymer Films
IEEE Transactions on Electronics Packaging Manufacturing, 2009Ultrasonic hot embossing allows fabrication of metal patterns onto a polymer film with a low cost and rapid process. A polymer layer with a thin metal film on top is welded onto the polymer substrate where there are protruding micro structures on the tool. Edges around the protruding structures cut the metal layer and ensure electrical insulation.

Ultrasonic Vibration Hot Embossing
International Polymer Processing, 2005Abstract Hot embossing has become a popular method for replicating precise micro-features onto large plastic plates. However, a long cycle time of the process due to conventional electric heating or hot oil heating is one of problems that confound the overall success of this technology. This study proposed a novel hot embossing method by

Modeling the Embossing Stage of the Ultrasonic‐Vibration‐Assisted Hot Glass Embossing Process
International Journal of Applied Glass Science, 2014Ultrasonic vibration technology has recently been applied in high‐temperature forming processes, such as hot upsetting and hot glass embossing. Experimental research has delineated the effects of ultrasonic vibration on reducing required forces and improving the formability of materials. The purpose of this study was to construct a finite element model
