Casting Assignment #2

The part shown to the right needs to be cast. Design a blind riser to be made in the shape of a sphere, such that the solidification time is 30% greater than the part time. Use Chvorinov's equation for solidification time, with B=1 and n=2.

Volume of part shown: _________ (xx.xx in³)

Surface Area of part shown _________ (xx.xx in²)

Minutes required to solidify the riser = ____________( x.xxx min)

Diameter of the sphere used as a blind riser: _______________ (x.xxx in)

The parting line of a casting is the largest cross-sectional profile of the part. In this case, determine the area of the pattern directly on the parting line.: _____________(x.xx in²)
