[Foundry Process] Die Casting [Process] This process is used for producing large volumes of zinc, aluminum and magnesium castings of intricate shapes. The essential feature of diecasting is the use of permanent metal dies into which the molten metal is injected under high pressure (normally 5000 psi or more). The rate of production of diecasting depends largely on the complexity of design, the section thickness of the casting, and the properties of the cast metal. Great care must be taken with the design and gating of the mold to avoid high-pressure porosity to which this process is prone. [Pros / Cons] 
Advantages Cost of castings is relatively low with high volumes. High degree of design complexity and accuracy. Excellent smooth surface finish. Suitable for relatively low melting point metals (1600F/871C) like lead, zinc, aluminum, magnesium and some copper alloys. High production rates. Disadvantages Limits on the size of castings - most suitable for small castings up to about 75 lb. Equipment and die costs are high.
