Abstract
In this study, the micro metal injection molding method inserted plastic sacrificial mold was proposed in order to solve some problems, such as filling in narrow cavity, poor mold transcription, difficult de-molding and handling operations, etc. in micro metal injection molding (μ-MIM). Using the minute mixing-injection-molding machine, PMMA sacrificial mold with the zigzag spring shaped micro cavity and the green compact were prepared by sequential 2-step injection molding method. Molding properties of PMMA sacrificial molds and the green compacts were evaluated.
