고품질 구상흑연주철 주조품을 위한 무압탕 주조 공법 사례 연구 : 수출용 상용 브레이크 HUB 내부 무압탕 주조 공법을 통한 원가절감 사례 연구

다국어 초록 (Multilingual Abstract)

Maximizing profit through cost reduction is fundamental in the manufacturing industry. The major purpose of this research report is to study the best way to produce high-quality products without using a riser on a export commercial brake hub made by ductile cast iron. This research made it possible to reduce costs by increasing the recovery rate of castings, minimizing finishing processes, and lowering energy consumption and environmental problem. This research report is to save about 100 million won per year in economical aspect. At the same time, this research report will bring a positive effect that a corporation could extend an export market portion by applying this technology to similar products.
