Abstract
Data analysis and simulations of micro‐moulding experiments have been conducted. Micro
moulding simulations have been executed by implementing in the software the actual processing
conditions. Various aspects of the simulation set‐up have been considered in order to improve the
simulation accuracy (i.e. decrease deviations from experimental values): injection speed profile,
cavity injection pressure, melt and mould temperatures, three‐dimensional mesh parameters, and
material rheological characterization. Quality factors investigated for the quantitative comparisons
were: short shot length, injection pressure profile, moulding mass and flow pattern.
The importance of calibrated micro moulding process monitoring for an accurate implementation
strategy of the simulation and its validation has been demonstrated. In fact, inconsistencies and
uncertainties in the experimental data must be minimized to avoid introducing uncertainties in the
simulation calculations.
Simulations of bulky sub‐100 milligrams micro moulded parts have been validated and a
methodology for accurate micro moulding simulations was established.
