冲压是一种冷冲压加工方式，系借助于常规或专用冲压设备的动力重击材料（金属或非金属），将其裁切、折弯或塑造成模具所规范的成品形状与尺寸中。冲压加工大致可区分成剪切、弯曲、成型及引伸等几种不同的加工型式。

冲压所用的工具机称为冲床，而所用的模具则称为冲压模具。

Stamping (also known as pressing) is the process of placing flat sheet metal in either blank or coil form into a stamping press where a tool and die surface forms the metal into a net shape. Stamping includes a variety of sheet-metal forming manufacturing processes, such as punching using a machine press or stamping press, blanking, embossing, bending, flanging, and coining. This could be a single stage operation where every stroke of the press produces the desired form on the sheet metal part, or could occur through a series of stages. The process is usually carried out on sheet metal, but can also be used on other materials, such as polystyrene.
