THE EFFECT OF POLYMER SELECTION AND LEVEL ON SHELL PROPERTIES

摘要

A significant number of investment casting foundries add organic polymers to their backup slurry systems to make process improvements. These improvements can be in added green strength or permeability, better rheology, and thicker shells. etc. This paper will look at the relationship between polymer selection, use level, and viscosity to previously mentioned properties. The individual foundry can then use these results to optimize the polymer type, level and viscosity for their specific needs.
