Sheet metal stamping is a forming and processing method that mainly relies on presses and dies to apply external forces to plates, strips, tubes and profiles, etc., to plastically deform or separate them, so as to obtain workpieces of the desired shape and size (stamped parts) . In the sheet metal stamping process, three main types of dies are used - cutting, punching and bending :
Cutting: involves cutting a part from a sheet of metal. This is done by impacting the sheet metal with a punch, which shears the sheet metal into the desired shape. The edges of the punched part will have burrs, so they need to be filed or machined before use .
Punching: is the process of punching a hole in a sheet of metal by placing it between two punching dies and forcing them together.
Bending: is the deformation of metal through the use of pressure from a die, this type of stamping is often used to make parts with curves.
Sheet metal stamping process performance is excellent, high production efficiency, easy to operate, easy to realize mechanization and automation, with high dimensional accuracy, stamping parts have good interchangeability The process performance of sheet metal stamping is excellent.
Stamping: The whole roll of steel or aluminum plate will be continuously stamped into small sheet metal parts by several large presses. Stamping.
Welding: Stamped sheet metal parts are welded together to form the body structure, including the four doors and front and rear covers (hood + trunk lid), and the finished welded body structure is the body-in-white. Welding
Separation process: the sheet is separated along a certain contour line under the action of external force to obtain a certain shape, size and quality of the cut surface of the finished and semi-finished products. Separation process.
Forming process: the billet in the conditions of non-breakage to produce plastic deformation to obtain a certain shape and size of the finished and semi-finished products. Forming process.
Unwinding line: a large number of coils and strips are used to realize uncoiling, leveling, shearing or dropping and stacking of coils. Unwinding line: a large number of coils and strips are used to realize uncoiling, leveling, shearing or dropping and stacking.
Automated production: The production line of large body covering parts is mechanized or automated, with robots, manipulators or cross-bar transfer devices between processes. Automated production: the production line of large body covering parts is mechanized or automated.
Progressive die production: small and medium-sized stamped parts are produced using progressive dies. The

Material optimization: The stamping process makes efficient use of materials and minimizes waste, resulting in cost savings and reduced environmental impact. .
Integration with other processes: Sheet metal stamping can be integrated with other manufacturing processes such as laser cutting, bending and forming to produce a wide range of components and meet the diverse needs of the automotive industry.
Body Panels: Sheet metal stamping is widely used in the manufacture of body panels, including doors, hoods, fenders and trunk lids. These components require precise stamping to achieve the desired fit and appearance.
Chassis components: Sheet metal stamping is used to manufacture chassis components such as brackets, mounts and reinforcements. These components provide structural support and ensure the integrity and stability of the vehicle. Chassis Components.
Exhaust Systems: Sheet metal punching is used to punch and perforate holes in exhaust systems to promote proper airflow and reduce back pressure. This improves engine performance and fuel efficiency .
Interior Components: Various interior components of a vehicle, such as seat brackets, console panels and instrument panel components, are manufactured using sheet metal stamping. These components require precise stamping to ensure proper fit and function.
Heat shields: Sheet metal stamping is used to manufacture heat shields, which are used to protect sensitive components from high temperatures. These shields are vital to maintaining the safety and performance of the vehicle.
Electroplating: In an electroplating solution, charged ions attach to the surface of a product under the action of an electric field to form a plating layer. Commonly used plating includes zinc, cadmium, copper, chromium, tin, nickel, gold, silver, etc.
Powder Coating: Powder Coating is a coating process that uses corona discharge to make powder coatings adhere to the workpiece. After powder coating and then through the steps of heat fusion and curing, it will form a coating film on the surface of the workpiece. The powder coating film is formed on the surface of the workpiece after heat fusion and curing steps.
Electrophoresis: Electrophoresis process is divided into anodic electrophoresis and cathodic electrophoresis. If the paint particles are negatively charged and the workpiece is the anode, the paint particles are deposited into a film on the workpiece under the action of electric field force, which is called anodic electrophoresis; on the contrary, if the paint particles are positively charged and the workpiece is the cathode, the paint particles are deposited into a film on the workpiece, which is called cathodic electrophoresis. The opposite is called cathodic electrophoresis.
Plastic Dipping: Plastic Dipping alias also known as Plastic Coating, Thermal Dipping, Heat Applied Plastic Coating. Immersion molding (plastic coating) is a plastic coating process. According to the different raw materials used in dip molding can be divided into liquid dip (coated) plastic and powder dip (coated) plastic. The following are some of the most common types of plastic dip molding.
Oxidation: Oxidize the metal on the surface of the workpiece to form a dense protective film on the surface of the workpiece to increase the corrosion resistance of the workpiece. Oxidizing.
Brushing: Surface brushing is a means of surface treatment by which abrasive products form lines on the surface of a workpiece to provide a decorative effect. The surface brushing is a kind of surface treatment.
Imprinting: Imprinting is the process of changing the thickness of the material, filling the extruded material into the undulating die cavity, so as to form an undulating pattern or lettering on the part. Stamping.
Baking paint: through spraying, high temperature baking, etc., on the surface of the material sprayed with a variety of colors of paint used to beautify the appearance and can increase the corrosion resistance. Baking Paint.
