Abstract:In this paper, the inherent relationship between the negative pressure and the adhesion to sand formed in AL alloy casting in evaporative pattern casting has been studied. The author points out technologically that another effective way to pvevent the adhesion to sand lies in selecting suitable original negative pressure and gating system size.
Keywords:evaporative pattern casting  Al alloy  negative pressure  adhesion to sand
