Casting and forging processes are often required or recommended for custom parts having complex shapes. Both of these fabrication methods have many advantages, although casting is preferred when closer tolerances are necessary, or for parts having thinner walls. Parts fabricated by casting also tend to have much lower finishing costs than is the case with forged parts.
There are various brass casting processes, but die casting is by far the most common. The use of identical permanent molds makes die casting an ideal process for mass production of complex parts. Die cast parts are typically sharply defined, and noted for their accurate dimensioning. Parts surfaces can be smooth or textured, and can easily be finished or plated. Casting is a preferred process of mass producing complex parts, since there is usually no need for machining. Die cast parts are also noted for their strength when compared against welded or fastened parts, since the strength of the brass or brass alloy exceeds the strength afforded by a joining process.

Custom Permanent Mold Castings
|Permanent mold casting is a brass casting process that employs reusable “permanent” brass molds. It is often referred to as gravity die casting because brass is typically poured into the die under gravity-induced pressure instead of using forcible injection. Some manufacturers use other processes as well, such as pouring molten brass under high gas pressure or vacuum pressure.
