Design and Optimization of Low Pressure Casting Process Parameters for Aluminium Alloy Battery End Plates
Based on an orthogonal experimental design and signal-to-noise ratio analysis,the effects of three process parameters-casting temperature,mold preheating temperature and mold filling time-on casting quality in low-pressure casting were investigated,and a set of standardized process design parameters using shrinkage rate and shrinkage pore volume,solidification time and secondary dendrite interval as evaluation indicators were explored.A set of standardized process design parameters was investigated as an important reference for the study and practical application of a low-pressure casting process for aluminum alloy battery end plates for new energy vehicles.The results showed that the casting temperature of 690 ℃,the die preheating temperature of 330 ℃ and the filling time of 8s resulted in no shrinkage or shrinkage of the castings,the smallest secondary dendrite spacing and the shortest solidification time.
