A fast method to predict the cooling time of wax for investment casting procedure

The investment casting of metal parts is a rapid tooling/manufacturing method for small series production, where wax pattern is produced separately and then extracted from the mould. The wax parts commonly used as patterns are usually obtained after wax casting silicone rubber moulds. The time needed for the wax to solidify is critical and difficult to predict. This article present an experimental method for cooling-time determination using a simplified applicable solution (needed in hash industrial enviroment and short deadlines) based on real-life parts experience.
