Abstract

A series of investment casting waxes has been tested at industrially relevant processing conditions using thermal, mechanical and rheological measurement techniques at the National Physical Laboratory (NPL) as part of a collaborative research programme with British Investment Casting Trade Association (BICTA) member companies. Five measurement methods (Differential Scanning Calorimetry, Thermal Conductivity, Pressure-Volume-Temperature, Viscosity and 3-Point Bend Creep) were employed to characterise waxes, which were latter subjected to industrials trials in six U.K. foundries to assess their performances. The waxes were selected from a range of pattern and hydrocarbon waxes in unfilled and filled (cross-linked polystyrene, acid and water) conditions. The results of this pilot study and industrial trials are discussed in this report. The published literature on investment casting waxes has been briefly reviewed.
