During production, a plastic film is pressed between two induction units with replaceable stampers, with a pattern which will be transferred to the film. In the process, the plastic is heated in a few seconds up to the desired temperature (usually about 200° C) whereby the plastic becomes soft and the pattern is transferred. Immediately afterwards, the plastic film is cooled fast down to room temperature.
With our rapid and smooth heating process, it is possible to replicate advanced patterns down to nano-level. This exact heating process, in combination with rapid cooling, ascertains that the plastic material is never overheated.
As a result, the substrate and final product will be free of common defects such as brittleness, stress and birefringence.
