Molding and Optimization of Injection Conditions on Shrinkage for Thin-Walled Wax Part Using RSM-GA Method

Abstract

Abstract:

Abstract： A response surface methodology(RSM) model was built to describe the relationship between the shrinkage in the thickness direction of the thinwalled wax part and injection parameters through experiments. The rationality and adequacy of the model were checked via analysis of variation(ANOVA). Besides, a sensitivity analysis for injection parameters on the dimensional shrinkage variation was conducted. Additionally, in order to reduce the shrinkage, the optimal injection conditions were also obtained by calculating the desirability and genetic algorithm(GA) approach.

Key words: wax injection, thin-walled wax part, response surface methodology （RSM）, genetic algorithm （GA）, shrinkage, investment casting
