Abstract

Filling and solidification of different squeezing casting schemes were simulated with the help of the Flow-3Dfor thin-walled high strength-ductility piston for light-loading power machinery to determine the optimized parameters and mould structure.Based on the Flow-3Danalysis

the mould structure was optimized.The practical production verified that the optimized design is feasible

meeting the piston requirements.
