In this paper, grid generation and injection analysis were carried out by using Moldflow AMI which is a commercial forming analysis program to minimize resin shot defect generated in metal injection molding according to 19mm diameter BTA drill head design. Molding condition suitable for process of target goods was set in moldfolw, based on the result, gate location, weld line and packing time were set and flow characteristic, such as filling pattern, pressure distribution was measured by injection molding analysis. This paper is directed to improving quality of injection molding product by analyzing estimated volume contraction, air trap, weld line, sink mark, filling power and grow form and so on and considering the best result.
