Thin wall injection molding of thermoplastic microstructures

摘要

Thin-wall injection molding is a key technology allowing the low-cost mass production ofmicrostuctures, such as devices with surface-relief microcomponents widely applied in micro-optics, micro-fluidics, medical and biotechnology. Research was performed in order to gain better understanding of important parameters in injection molding of thin-wall microstructures. A series of injection molding experiments were conducted with PC and PMMA, which are common materials in bio-MEMS(Micro Electro Mechanical System) applications.
