Abstract

Experimental flow analysis and verification of computer simulation have been carried out in order to apply them to die casting. Despite much work in this field, no work has been published confirming the accuracy of a simulated result. Different flow simulation softwares have been studied for several years, and this work reports flow visualized experimental results compared with computer-simulated results. The experimental equipment used for flow visualization has comparable dimensions to a real die casting machine and is equipped with a transparent mould, a shot sleeve and an injection plunger whose speed is servo-controlled and measured. Mould filling water is either mixed with micro-sized tracer particles or dyed. Three transparent moulds, whose shapes are rectangular, a two-dimensional section model of a wheel and a three-dimensional shape, are observed. Several sets of software were examined and compared with the experimental results. Finally, some new software, named STEFAN, was found to show good results.
