Permanent Mold Castings: Pathway to Quality
by the process. The metal near the die cast surface does exhibit a fine grain structure. However, when molten metal is injected into the die cavity under pressure, air often becomes entrapped in the metal. Also, after the metal is injected into the die, additional metal cannot flow into the cavity

Car designers are "hip" to aluminum castings
that pack well, such as brake calipers and steering knuckles. Bodycote says HIP works well for most investment, sand, and permanent mold (gravity die) casting. High-pressure die and lost-foam castings can, however, have surface porosity and trapped air pockets that HIP may not be able to get out

Investment Casting
is cast, and when cool, the mold material is removed by impact, vibration, grit blasting, high pressure water blasting or chemical dissolution leaving the investment castings, which are then removed from the runner system.

Where die casting makes "cents"
must be to function properly. Tailoring the alloy for individual components while using an unvarying production process helps reduce overall costs. Choosing a casting process. The choice of alloy and component size dictate which die-casting process to use. Pressure die casting is the most common method
