금속사출성형기법을 이용한 플랜지 제작기술에 관한 연구

다국어 초록 (Multilingual Abstract)

MIM(Metal Injection Molding) that is a kind of PIM(Powder Injection Molding) is using in optical communication field, display field, several fields such as semi-conductor field because ceramic has superior physical properties. Also, mold's optimization that can produce high precision flange that is one of main parts of optical communication field is greatly required. The objective of this paper is to study the suitability of design and capability analysis for the MIM and process that can mass-produce the flange using in a mold by conduct the experiments as well as the flow analysis. It was filling time 0.5~1.5 second, injection pressure 11.0~12.5 ㎫ range for the injection parameters that cause high effect to injection derived from optimum condition by flow analysis. Yield that is more than gravity 7.495 that establish by target as result that analyze gravity of products at investigated injection conditions was 99.01 % and process capability was construed by 3.83 sigma level. Also, the average gravity and standard deviation was 7.6151 and 0.0511 respectively. The measured dimensions were all good results within the established target showing that concentricity, roundness, and density were 27.43 ㎛, 18.64, and 97.63%.
