Metal Stamping Services

Metal stamping is used to fabricate metal parts in high volumes at a very low manufacturing cost per unit. The term usually encompasses a wide variety of sheet-metal forming production processes, either single-stage or multi-stage in scope.

METAL STAMPING


Metal stamping is used to fabricate metal parts in high volumes at a very low manufacturing cost per unit. The term usually encompasses a wide variety of sheet-metal forming production processes, either single-stage or multi-stage in scope.

In a single stage metal stamping operation, every single stroke of a press creates a metal part or desired shape from a strip of metal or a piece of sheet metal. By contrast, during multiple stage metal stamping operations, a metal component undergoes multiple press strokes and/or tool and die procedures. This form of fabrication involves greater complexity.

Bunty LLC offers high quality metal stamping services and products for use in different kinds of industries. Our precision metal stamping presses vary in size from 15 tons to 1,500 tons, which allows us to furnish custom metal stampings in a wide range of sizes. Stampings can be produced in stainless steel, aluminum, carbon steel, cobalt alloys, and nickel alloys through the following metal stamping processes we specialize in:

·        Blanking;

·        Deep drawing;

·        Die cutting;

·        Progressive die stamping.

·        Multi-side die stamping;

·        Coining.

We ensure comprehensive monitoring and inspections throughout the whole production process.  To promote better quality control, we'll inspect parts for accuracy and quality, and conduct accountability testing of the stamped metal components.

 

Metal stamping processes

The specific metal stamping process may vary significantly, depending upon customer specifications.
 

Blanking

Blanking is a metal fabricating process during which sheet metal or metal strips are punched in order to fabricate desired metal workpieces. The force of punching removes material from the metal sheet, creating a new piece or ‘blank’. This process permits rapid manufacturing of blanks of various shapes and is suitable both for high volume and medium volume levels of production. Common materials used for blanking include aluminum, brass, bronze, steel, and stainless steel.

In deep drawing, the mechanical action of a punch forces a sheet metal blank radially into a forming die, to the point that the depth of the drawn part eventually exceeds its diameter as the part enters a series of dies. This process is used for the production of very precise and intricate metal parts that can be both symmetrical and asymmetrical. Parts can come in a wide range of sizes, varying from 0.25 inches in diameter to large mechanical components used in aircraft and automotive industries. They are typically made out of copper, brass, aluminum, cold rolled steel or stainless steel.

The process of deep drawing can offer the advantages of reduced waste, much lower assembly costs, and improved strength.
 

Die cutting

Die cutting is a high-volume manufacturing process used to cut a thin flat item into a desired shape using a steel cutting die, a machine that functions similarly to a press. The cutting die functions as a template, enabling the production of identical parts quickly and easily. The parts are typically cut from sheets of metal, paper, foam, plastic, and other materials. Some examples include seals, shims, templates, gaskets, washers, puzzle pieces, and inserts.

This process is widely used to produce low-cost parts for various industries. During progressive die stamping, an automated feeding system typically pushes a metal strip through a series of several individual work stations in the progressive stamping die assembly. At every station, one or more unique operations occurs impacting the metal part. These may include bending, punching, coining and other modifications. Progressive die stamping can form metal parts made from brass, copper, nickel, aluminum and stainless steel.
 

Multi-side die stamping

Multi-side die stamping represents a somewhat more complex process than other types of metal stamping. It essentially involves successive or simultaneous shaping of a metal wire or other metal piece by means of multiple dies. This custom process is often employed to work with cold rolled steel, stainless steel, spring steel, aluminum, copper, and brass. It works well to produce complex small parts that involve multiple bends or coils, such as springs, clips, brackets, and similar metal components used in numerous industries, particularly the construction and automotive industry.
 

Coining

Unlike stamping operations that cut metal by means of a die or a punch, coining doesn’t remove any material. Instead, the coining machine employs a gear-driven press, a hydraulically activated press, or some other mechanical press capable of exerting a lot of force. This force is then used to displace material held within the press to form a desired shape. This metal stamping process can be used to create durable functional components on a part designed to interact with other parts.
