Maximum wall thickness

Decrease the maximum wall thickness of a part to shorten the cycle time (injection time and cooling time specifically) and reduce the part volume
Uniform wall thickness will ensure uniform cooling and reduce defects

Round corners to reduce stress concentrations and fracture
Inner radius should be at least the thickness of the walls

Apply a draft angle to all walls parallel to the parting direction to facilitate removing the part from the die.
Aluminum: 1° for walls, 2° for inside cores
Magnesium: 0.75° for walls, 1.5° for inside cores
Zinc: 0.5° for walls, 1° for inside cores

External undercuts require side-cores which add to the tooling cost
Some simple external undercuts can be cast by relocating the parting line
