Molding Technique for Improvement in Dimensional Accuracy of Micro-MIM Components
Conference: Powder Injection Molding 2005 (PIM2005) in March 20-23, 2005
San Diego, California Doubletree Mission Valley Hotel
Micro metal injection molding (Micro-MIM) is one of premising processes to manufacture tiny metal parts. Micro dumbbell specimens were molded by a micro injection molding machine, the mold pressure in injection process was measured at the both side chucking portions, and the effects of injection volume on the mold pressure and dimension in green compacts and sintered bodies were investigated. Dimension of molded parts and sintered ones were correlated by injection volume and then the possibility for dimensional control by the mold pressure was shown.
