Before a designer or engineer can utilize aluminum die casting to its full potential, it’s important that they first understand the design limitations and common geometric features that can be accomplished with this manufacturing technique. Here are some factors that you should keep in mind when designing a part for aluminum die casting.

Draft – In aluminum die casting, the draft is considered as the amount of slope given to the cores or other parts of the die cavity, which makes it easier to eject the casting from the die. If your die cast is parallel to the opening direction of the die, the draft is a necessary addition to your casting design. If you optimize and implement a proper draft, it will be easier to remove the aluminum die casting from the die, increasing precision and resulting in higher quality surfaces.

Fillet – The fillet is a curved juncture between two surfaces that can be added to your aluminum die casting to eliminate sharp edges and corners.
Parting line – The parting line is the point where two different sides of your aluminum die casting mold comes together. The parting line location represents the side of the die that is used as the cover and which is used as the ejector.

Bosses – When adding bosses to aluminum die casting, these will act as mounting points for parts that will need to be mounted later on. In order to optimize the integrity and strength of bosses, they should have the same wall thickness throughout the casting.
Ribs – Adding ribs to your aluminum die casting will grant more support to designs that need maximum strength while still maintaining the same wall thickness.

Holes – If you need to add holes or windows into your aluminum die casting mold, you’ll need to consider the fact that these features will grip to the die steel during the solidification process. To overcome this, designers should integrate generous drafts into hole and window features.
