Product Introduction
Sheet metal stamping refers to the process of applying pressure to metal sheets using stamping equipment (such as a press) and dies, causing the material to undergo plastic deformation or separation, thereby producing components with specific shapes, dimensions, and properties. It is one of the primary methods of metal forming, characterized by high efficiency, low cost, high precision, and excellent consistency, making it a crucial technique in industrial manufacturing.
Commonly used materials for sheet metal stamping parts are diverse and plentiful. In addition to the familiar cold-rolled steel sheets, hot-rolled steel sheets, stainless steel plates, and aluminum sheets, there are also copper plates and titanium alloy sheets. Cold-rolled steel sheets, with their excellent stamping performance and superior surface quality, are widely employed in automotive body panels and appliance casings. Stainless steel plates, renowned for their outstanding corrosion resistance and strength, are frequently used in medical devices and kitchenware. Aluminum sheets, prized for their lightweight nature as well as excellent electrical and thermal conductivity, play a vital role in aerospace, electronics, and telecommunications industries. Meanwhile, copper plates, thanks to their exceptional electrical conductivity, are predominantly utilized in electrical connectors and other similar applications.
Its manufacturing processes mainly include two major categories: separation processes and forming processes. Separation processes involve cutting the stamped part away from the sheet material along a defined contour, while ensuring that the resulting cut surfaces meet quality standards. Common examples include punching, blanking, and shearing. For instance, blanking involves punching out a workpiece of a specific shape from a sheet, which can then serve as a stamped part or a semi-finished product for further processing. On the other hand, punching creates holes of various shapes directly in the sheet material. Forming processes, meanwhile, induce plastic deformation in the sheet metal without causing it to fracture, enabling the creation of parts with desired shapes and dimensions. These processes primarily include bending, deep drawing, bulging, and flanging. Bending is similar to the fabrication of sheet-metal folded components—it involves shaping the sheet into angles and curvatures of specified degrees. Deep drawing, on the other hand, transforms a flat blank into an open, hollow component; for example, automotive fuel tanks and beverage cans are both produced using this deep-drawing process.
Sheet metal stamping components find applications across a remarkably wide range of industries. In the automotive industry, most exterior body parts—such as doors, hoods, roofs, and fenders—as well as numerous structural elements in vehicle frames and chassis—are produced via stamping; in fact, stamped parts can account for 50% to 70% of an entire car. In the electronics and appliance sector, components like switch and socket housings, along with silicon steel laminations used in motors, and core parts such as evaporators and condensers in refrigerators and air conditioners, are also predominantly manufactured using stamping processes. In aerospace engineering, critical structural elements like aircraft fuselage skins and wing frameworks are similarly crafted with high-precision stamping techniques. Beyond these fields, sheet metal stampings are also extensively utilized in medical devices, hardware tools, consumer goods, and other industries.
