Other Statements: Why shape/dimension Rectification is necessary for castings
Not like machined parts, investment castings will deform in varying degree during production.
Usually, it is the biggest problem for this kinds of parts.
Several main reasons as below:-
@ Wax mold deformation (one main reason; wax is SOFT)
@ When casting process, during cooling down, SHRINKAGE will lead to deformation in different position/direction especially for those Asymmetrical part.
@ Part surface Shot Blasting also will lead deformation a little bit.
@ After Annealing Heat Treatment, Deformation also might happen after this process
