Shell Molding |
|
- Shell molding meets all the functional
requirements for the rotor -- as-cast tolerance, surface finish, and
level of detail.
- From a casting perspective, the shell mold
offers a thin-wall capability and a heat transfer efficiency that cannot
be achieved with green sand.
- The sand shell is set in a bed
of metal shot which gives improved heat transfer during
solidification.
- The higher cost of the metal tool
for the shell mold is acceptable, given the production run and the
production benefits.
