SMED 기법을 적용한 사출공정의 가동준비시간 단축 사례 연구

Abstract

Manufacturing organization must increase production process flexibility to cope with demand for high diversity and low quantity. To get greater flexibility, organization must find ways to reduce setup and changeover time through elimination of waste and non value added setup activities and convert time spent on changeovers to production time. SMED(Single Minute Exchange of Die) is one of the most successful lean production method for reducing waste in a manufacturing process. This paper describes the application of SMED concept for reduction of changeover time and increasing productivity in injection process industry. The process of reducing changeover time implemented in a case company is described in detail. The implementation has enabled reduction of injection mold changeover time by 81% after changing some of the internal activities to external activities and proper streamlining of activities using SMED technique.
