Tools for ultrasonic hot embossing [PDF]
, 2016 Ultrasonic hot embossing is an emerging technology enabling molding of thermo-plastic polymers in seconds. A stack of polymer foils is heated by the friction between the foils and protruding microstructures on a tool when ultrasonic vibrations are generated by a sonotrode. The polymer is molten and adapts to the shape of the microstructures on the tool.

Fabrication of polymer micro devices by ultrasonic hot embossing [PDF]
, 2008 In this thesis ultrasonic micro hot embossing is shown to be suitable for the fabrication of polymer micro structures and entire devices. Micro structures are generated in a couple of seconds. Similar as in hot embossing, a polymer film is softened by heating and a micro pattern is molded from a metal tool.
