Abstract

Based on the software Magma5.3

low pressure die casting simulations was carried out on the local defects of a lower cylinder blocks.The origination of defects was described and the simulated results were optimized by DOE Taguchi method.The results show that the optimization of cooling parameter and the structure of ingates can improve greatly defects.The defective rate was decreased by 98%.
