MODELING AND GRAPHIC OPTIMIZATION OF VACUUM CASTING PROCESS OF WAX PARTS IN FLEXIBLE MOLDS
The research presented in this paper aims at modeling and optimization of vacuum casting process wax parts in silicone rubber molds based on the response surface method (RSM) and bi-factorial dispersion analysis. In this case of wax parts casting, the dependent variable considered is mold filling time (tfill) and the independent variables are wax temperature (Tw) and mold temperature (Tm).In this particular case, the best combination of process parameters is determined by graphical optimization method.
