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.

Once the mold is prepared and the pattern (the model of the final product) is placed in it, an opening is created to allow the molten iron to flow in. When the iron solidifies, the mold is broken apart to extract the cast piece. This method is cost-effective and can produce complex shapes with good dimensional accuracy.
