Abstract
The work presented in this paper contributes to a wider research objective aiming at gaining a better understanding of the injection
moulding process at microscales. More specifically, it contributes to the development of a new modelling approach combining
experimental observation and mathematical modelling to characterise thermal contact resistance that results from the
imperfections present on the surfaces when two surfaces are brought in contact. Thus, this paper describes micro and nano
structuring technologies (Focus Ion beam and Laser Ablation) used to structure sapphire inserts that are used as ”windows” in the
injection moulding process, allowing thermal measurements with a high speed thermal camera whilst sapphire structures are filled
with polymer melt.
