Abstract

Abstract Sustainability is becoming the most important criteria in all aspect of human existence including manufacturing. Investment casting is an old manufacturing method of shaping various alloys. Moulding, melting, alloying, pouring, solidification and finishing are steps in investment casting. Melting and ceramic shell making are the main energy consuming process steps. Findings in this research shows shell making is consuming even more energy than melting and almost 60-75% percent of energy is used to melt gating and sprues. The purpose of this study is to explore “sustainable behaviour” by accurate control of wax room, ceramic shell process, drying, firing time and temperature as well as preheat, melting, pouring, time and temperature and also furnace design with appropriate insulation to save energy and materials. Application of the CRIMSON process in investment casting is also discussed.
