Abstract

The adhesion tension of commercial filled and unfilled waxes in contact with a representative 5 ceramic shell system used in investment casting was determined by the Wilhelmy plate method. The average adhesion tension force of four filled waxes reduced at a rate of approximately 6.0 x 10-8 Nmm-1 °C-1 and the unfilled wax at a rate of 3.4 x 10-8 Nmm-1°C-1. Adhesion tension measured by Wilhelmy plate method was compared to the surface tension of wax measured by the Du-Nuoy ring method. It is suggested that Du-Nuoy ring method is 10 the simplest practical experiment to obtain the characteristics of wax-shell interaction for modelling applications.
