After the dies are prepared, metal sheets—often made from materials such as stainless steel, aluminum, or brass—are fed into the stamping machine. The machine applies immense pressure to the metal sheet, utilizing the die to create the intended shape. This process can incorporate various techniques, including blanking, bending, piercing, and forming. The versatility of custom metal stamping allows for multiple operations to be executed in a single stroke, significantly enhancing production efficiency.

1. Cost-effectiveness One of the primary benefits of using prototype sand casting is its cost-effectiveness, particularly for low-volume production runs. The materials used in sand casting are relatively inexpensive, and the molds can be created more quickly than more complex metal molds used in other casting processes.
