doi:10.19491/j.issn.1001-9278.2011.03.015

Abstract

Abstract: The micro fluitlic chips were studied in this work. The configuration of the micro fluitlic chips were designed by software Moldflow，which was used to simulate the micro fluitlic chips under different process parameters. It showed that the melt temperature had little effect on the filling time，while filling rime decreases with increasing injection speed. Injection pressure decreases with increasing melt temperature and injection speed. The warpage of the fluitlic chip can be reduced by increasing the melt temperature and injection speed.

Key words: Micro Injection Molding, Micro fluidic Chip, Melt filling flow, Numerical simulation
