Abstract

Micro injection moulding (μIM) is the key replication technology for high precision manufacturing of polymer micro products. Data analysis and simulations on micro-moulding experiments have been conducted during the present validation study. Detailed information about the μIM process was gathered and used to establish a reliable simulation methodology suitable for μIM parts. Various Simulation set-up parameters that have been considered in order to improve the simulation accuracy: injection speed profile, melt and mould temperatures, 3D mesh, material rheology, inertia effect and shrinkage prediction. Quality factors investigated for the quantitative comparisons were: short shots length, injection pressure profile, moulding mass and flow pattern.
