Intercoat Drying and Shell Properties

摘要

Intercoat drying is an important step in the investment casting shell building process. The amount of water removed after each shell layer has been shown to have a large influence on mold properties. Unfortunately we do not have a clear understanding of how much water needs to be removed. We also do not have a reliable method for relating dryness measurement to the amount of water remaining in the mold. This study was conducted as an attempt to establish the relationship between degree of dryness, mold properties and the dryness measurement method.
