A Design Study in Aluminum Castings -Uplock
Support
Aluminum Casting
Hitchcock Industries casts the uplock
support in D357 aluminum in precision molds formed in no-bake sand.
No-bake sand is used for accurate dimensional control and to
achieve the required metallurgical structure and properties.
The mold system uses over 20 cores to form both the
internal and external features of the uplock
Uplock in the As-Cast Condition
Gating,
risers, and chills are closely engineered to optimize flow and fill into the thin walls of
the casting. This produces a casting free of misruns, shrinkage voids, and porosity.
