Die Casting (Pressure Die Casting)

Sometimes called “Pressure Die Casting”
Molds are used multiple times
Metal is forced into die under pressure
Better for high production
Molds are usually made of metal
Complex shapes are possible
Castings have to have a relatively low melting temperature
- Zinc
- Aluminum
- Magnesium
Design Considerations
- Design with draft angles
- Avoid Undercuts
- Avoid Cores
- Holes can be problematic
