Metal stamping is a manufacturing technique that transforms coil or flat materials into designated shapes. This process includes various molding methods, including drop feed, punching, embossing, and progressive die stamping. The choice of technique may depend on the complexity of the component, allowing for the use of a combination of methods or individual techniques. Metal stamping is highly effective for the mass production of diverse and intricate parts, ranging from automotive door panels and gears to small electronic components utilized in cell phones and computers.

Metal stamping services can be achieved through molds and mechanical equipment, usually involving a series of processes, including shearing, bending, pressing, etc.
This technology can be mass-produced in an efficient and precise manner, thereby reducing production costs and improving production efficiency.

Stamping Types

Progressive stamping uses multiple molds and steps to create deeper parts than would normally be possible with a single mold. It also allows for multiple geometries to be achieved through various molds for each part. This technique is best suited for high volume and large parts, such as those in the automotive industry. Transfer stamping is a similar process, except that progressive stamping involves attaching the workpiece to a metal belt that runs the length of the process. Transfer stamping removes the workpiece and moves it along a conveyor belt. 

Deep stamping creates stamped parts with deep cavities, such as closed rectangles. This process creates rigid parts because the extreme deformation of the metal compresses its structure into a more crystalline form. Standard stamping is also commonly used, and it involves the use of shallower molds to shape the metal. 

Four-slide press molding shapes parts from four axes rather than one direction. This method is used to make small, complex parts, including electronic components such as cell phone battery connectors. With greater design flexibility, lower production costs and faster manufacturing times, four-slide stamping is popular in the aerospace, medical, automotive and electronics industries. 

Hydroforming is an evolution of the stamping process. Sheet metal is placed on a bottom shaped die, while the top shape is a bladder filled with high pressure oil that presses the metal into the shape of the bottom die. Multiple parts can be hydroformed at the same time. Hydroforming is a fast and accurate technique, although it requires trimming the mold to cut the part out of the sheet. 

Stamping is the initial step before forming, where the part is cut from the sheet. Fine blanking is a variation of punching that allows for precise cutting with smooth edges and flat surfaces. 

Imprinting is another blanking process that creates small, round workpieces. Because stamping requires a great deal of force to form small pieces, stamping hardens the metal and removes burrs and rough edges. 

Punching is the opposite of dropping; it involves removing material from a workpiece rather than removing material to create a workpiece. 

Embossing creates a three-dimensional pattern on the metal, either raised on the surface or through a series of depressions. 

Bending occurs in a single axis and is typically used to create U-, V- or L-shaped contours. The technique is accomplished by clamping one side and bending the other over a mold or by pressing the metal into or against the mold. Flanging involves bending a protruding part or portion of the workpiece rather than bending the entire workpiece.
