Die Stamping

The die stamping process, also known as pressing, includes several processes, such as punching, blanking, piercing, coining, and others. Die stamping manufacturers follow detailed designs to guarantee that every punch produces the finest possible result.

Die stamping is a process that uses specialized tools called dies to create designs, which can range from simple everyday items to complex computer components. To do a single task or a series of tasks that happen one after the other, dies can be built per die stamping suppliers’ specific requests.

For die-stamping, there are three common manufacturing processes.

• Line: A single-step procedure
• Transfer: Stamping completes multiple tasks in a single cycle
• Progressive: The most typical and extensively employed

Die Stamping Operations

Cutting or shaping are the tasks that stamping dies can undertake; certain dies can combine these tasks. Every operation that die stamping producers undertake has the goal of causing separation or plasticizing so that it can take the shape of plastic.

Forming dies are:

• Bending
• Flanging
• Drawing
• Stretching
• Coining
• Ironing

Cutting dies are:

• Shearing
• Blanking
• Trimming
• Notching
• Piercing

A description of forming dies is provided below: Like a stencil, forming dies compress metals into precise forms.

Bending

A bend produces shapes resembling an L, U, or V. It is a plasticizing deformation that places stress along a single axis at the yield level below tensile strength.

Flanging

The workpiece is bent by flanging along a curved axis. Stretching and shrinking are the two sorts. The length of the tab affects the flanging process, which frequently involves tension and compression. However, with just a simple downward push motion, it is possible to create curves or corners.

Drawing

Drawing is a metal flow process that substitutes a different form with the same surface area for the workpiece's surface. The metal is still thick after being reshaped. Since it impacts how the part can be moved, cut, and expelled, the drawing orientation is crucial. Deep drawing is a type of drawing. Since it is non-directional, the direction may be vertical, up, or down.

Stretching

Tension and thinning increase the workpiece's surface area. For painting and finishing, it creates an incredibly smooth surface. High-pressure binding is used in dies to stop the metal's flow. Stretched metals are typically resistant to dents. Pre-stretched material is displaced into an alternate geometry.

Coining

Applying intense pressure and reducing the metal's thickness creates a pattern on the workpiece.

Ironing

Similar to coining, its goal is to squeeze the workpiece at a depth that is 30% of the workpiece's thickness to minimize the wall thickness of the workpiece. Ironing raises the drawn vessel's length and provides a uniform wall thickness.

As opposed to forming dies, cutting dies cut or remove material to produce items. Below we discuss the various types of cutting dies.

Blanking

When a metal strip is blanked, a section is removed along a certain contour line or shape. In the simplest terms, it involves separating one end of a strip from the other. In this process, the cutaway portion is the workpiece, and the remaining portion is scrap.

Piercing

Blanking and piercing go hand in hand. In blanking, the punched component turns into the usable part, which makes this difference between the two. With piercing, the portion is what is left after the excised piece is scraped off. The punch dimensions determine the size of the deleted component and the remaining hole.

Shearing

Although angle cuts are feasible, shearing generates a straight-line cut and is utilized for parallel cuts.

Trimming

To fit the appropriate profile, a form's outer edge is removed. This procedure is used to trim a flash, which is extra material surrounding a form during the die stamping process.

The top die trims the product, and the product enters the top die. To be ejected from the die, the product inside the die rises over the top die and is knocked out close to the top dead point. The knockout touches the bottom of the sketched product. When a product with a huge flange is being ejected, it's possible that it was deformed beforehand. Therefore, the knockout is produced to escape in the event of a product with a large flange in accordance with the drawing's diameter, and the ejecting is done at the flange part.

Notching

Bending or cornering procedures can be aided by notching. It is done to the outside of the workpiece to produce a particular profile.

In addition to stamping, machines may cast, punch, cut, and shape metal sheets. Each stamped component can be produced with great precision and repeatability using machines that can be programmed or controlled using computer numerical control (CNC). Programs for computer-aided design (CAD) and electrical discharge machining (EDM) ensure accuracy. There are numerous tooling machines available for the dies used in the stampings. The stamping needs are met by progressive, forming, compound, and carbide tooling. Progressive dies can simultaneously create several pieces on a single piece.
