Study Notes
Casting Part Design
- Uniform wall thickness in cast part design allows for more equal part shrinkage.
- This also enables better removal from the mold.
- Uniform wall thickness helps eliminate porosity in the cast part.
- It does not necessarily allow for more complex geometric shapes.
