Die Casting Campaign

On June 5, 2001, a die casting campaign was conducted at Briggs and Stratton Corporation’s Milwaukee die casting facility. The primary objective of the June 5th B&S die casting campaign was to produce aluminum alloy die castings with varying amounts of externally solidified product (ESP) for future characterization in keeping with the DOE project objectives. This section summarizes the die casting conditions used to produce those samples and preliminary observations relating to the resultant castings.

Part Description and Die Casting Machine Setup
 The die casting selected for production during this campaign was a Model 19 base, identified as Briggs & Stratton Part # 212143.This casting is similar to the casting shown in Figure 1 of the Characterization Section of the project webpage (www.mse.eng.ohio-state.edu/~mobley/diecasting). The designed total shot weight (total quantity of alloy poured) was 5.25 pounds, and the designed resultant weight of the casting and overflows was 4.0 pounds. The die casting alloy was a modified 383 aluminum alloy of the composition given in Table 1.
