Author(s)Tor, Shu Beng; Loh, N.H.; Fu, G.; Tay, B.Y.
In this paper experimental study on the demolding force needed to eject micro structures in Micro Metal Injection Molding (μMIM) is conducted. Injection molding is done on a variotherm mold mounted on a Battenfeld injection molding machine and demolding force measurement is done on an Instron tensile testing machine. Green part is a round disc of φ16 mm and thickness 1.5 mm with an array of φ100 μm × height 200 μm micro structures at the center. The experimental results are in good accordance with the previous analysis results.
