Benchmarking Shell Recycling, Productivity Metrics, and Risering Practices in the North American Investment Casting Industry
摘要
This paper documents the results of a recent survey of the domestic investment casting industry. It was conducted in support of a research project cosponsored by the project team and by the Defense Logistics Agency Troop Support, Philadelphia, Pennsylvania and the Defense Logistics Agency Information Operations, J68, Research and Development, Ft. Belvoir, Virginia. The 26-question survey was intended to take ~30 minutes to complete and shed light on prevalent industry practices related to risering castings, shell and casting productivity, and the use/opportunity involved in recycling investment casting shells. The results largely confirmed the research team’s observations of the industry and provided metric references for the various opportunities involved in developing improved risering tools/technologies specific to investment castings, recycling shells, and improving productivity in shell (and casting) production.
