Metal stamping is a cold forming process that uses molds and punches to transform metal sheets into different shapes. A flat sheet of metal (commonly called a blank) is fed into a sheet metal stamping machine, which uses tools and mold surfaces to shape the metal into a new shape, as is the case for Automobile Press Parts . Production facilities and metal manufacturers that provide stamping services place the material to be stamped between the mold parts, where the use of pressure will shape the material and cut it into the final shape required for the product or component.
Basic concepts of stamping
Metal stamping, also known as stamping, is a low-cost, high-speed manufacturing process that can produce a large number of identical metal parts. Stamping operations are suitable for short or long-term production and can be performed in conjunction with other metal forming operations and can consist of one or more of a series of more specific processes or technologies, such as:
stamping
Blank
Embossing
Coin
bending
Flanging
Punching and blanking refers to the use of a die to cut the material into a specific form. In the punching operation, when the punch enters the mold, a piece of debris is removed, effectively leaving a hole in the workpiece. Blanking, on the other hand, removes the workpiece from the main material, making the removed part the desired workpiece or blank.
Embossing is the process of creating a raised or recessed design in a sheet metal part by pressing the original blank against a mold containing the desired shape or passing the material blank through a rolling die.
Embossing is a bending technique in which a workpiece is punched when placed between a mold and a punch or punch. This action causes the punch to penetrate the metal and results in accurate, repeatable bending. Deep penetration can also relieve internal stresses in metal workpieces, so there is no rebound effect.
Bending refers to the general technique of forming a metal into a desired shape, such as an L, U, or V-shaped profile. The bending process of metal results in plastic deformation, the stress of which is higher than the yield point but lower than the tensile strength. Bending usually occurs around a single axis.
Flanging is the process of introducing a torch or flange into a metal workpiece by using a mold, press, or special flanging machine.
Metal stamping machines can do more than just punch. They can cast, stamp, cut and form metal plates. The machine can be programmed or computer numerically controlled (CNC) to provide high precision and repeatability for each stamped part. Electrical discharge machining (EDM) and computer-aided design (CAD) programs ensure accuracy. There are various machine tools for stamping dies. Progressive, forming, compounding and cemented carbide dies perform specific stamping needs. You can use progressive dies to create multiple parts on a single part at the same time.
