Abstract: A method of forming micro-channels in a plastic surface using a pressing device includes structuring a micro-channel forming tool for the pressing device to include a press end including a press surface that extends along a plane and a micro-channel detail positioned on the press end and extending beyond the plane of the press surface. The micro-channel detail includes a non-critical portion and a critical portion supported by the non-critical portion. The press end of the micro-channel forming tool is driven into the plastic surface at a predetermined force using a pressing device. Ultrasonic vibrations are applied to the micro-channel forming tool for a predetermined amount of time to melt portions of the plastic surface in contact with the pressing surface. The ultrasonic vibrations are removed after the predetermined amount of time has elapsed and the press end is retracted from the plastic surface.
