Abstract

Industrial interest in micro-fabrication techniques has mushroomed in the wake of recent advances in microtechnology, notably LIGA technology \ which provides a cheap and effective route to the mass fabrication of complex micro- structures. At the heart of LIGA technology is the injection moulding process. This paper investigates current state-of-the-art injection moulding simulation software for use as design tools in the development of micro-parts. We have investigated the flow of poly(oxymethylene) in 400 um wide channels of rectangular cross-section (depth 40-500 uin) and under a range of injection pressures. The flow lengths obtained were found to be in good
