  • Progress in Investment Castings - IntechOpen

    2012-12-3 · Patterns for investment casting produced in dies are prepared for assembly in different ways. Large patterns are set-up and are processed individually, while small to medium size pat‐ terns are usually assembled into clusters for economy in processing. For example, pattern clusters of aircraft turbine blades may range from 6 to 30 parts.
