Abstract
In this
paper , deformation and stress of casting shell and the resin prototype pattern are analyzed, getting the criterion of
non crack. And sol id prototype pattern which is in the diameter of 30mm and hollow prototype pattern which is in the
diameter of 30mm with thickness of 1mm are prepared, then coated and sanded, baked to get the casting shell. The results
show that criterion of non crack of casting shell is based on cross sectional ratio M of casting shell, and hollow prototype
pattern is more reasonable. When charging temperature is 80 to 100 o C , heating rate is 150 o C /h, the prototype pattern is
heated to 950 o C for 30min, then the integrat ed casting shell is obtained..
