Lessons Learned

The redesign of the gating system for the crossbleed valve was an excellent demonstration how the casting design process can produce cost-effective solutions to production problems.

Major lessons learned were:

Controlled solidification can be produced in isolated hot sections by well thought-out design of the gating on the casting. This ensures a flaw-free, in-spec component.
Close communication with the end-user was necessary to approve the design change needed to achieve the directional solidification.
The investment casting design can be easily modified by low-cost additions and deletions to the wax pattern.
