Progressive stamping is a technique used in the manufacturing industry that has revolutionized the way many metal products are produced. This process, which involves the progressive forming of metal sheets through a series of sequential operations, is a key component in the production of parts for numerous industries.
At Bericht we are experts in the manufacturing of metal parts for various sectors. We are very familiar with this manufacturing technique, and in this post we explain it clearly.
What is progressive stamping?
Progressive stamping is a highly efficient manufacturing process used to transform metal sheets into complex and precise components. In this method, a strip of metal is fed through a series of stamping stations where various forming operations are performed, such as cutting, bending, drawing, and punching.
Each station performs a specific task, and the blank piece gradually moves through the set of tools to complete the process. This sequence allows for the mass production of components with tight tolerances and intricate geometries, making it an ideal option for manufacturing parts in numerous industries.
The progressive stamping process
The progressive stamping process consists of several phases that allow for highly efficient and cost-effective production of complex metal parts.
It involves a series of coordinated operations carried out in a progressive stamping press.
- Cutting: this stage involves trimming the metal sheet to form the blank piece with the required general shape.
- Bending: in this phase, mechanical forces are applied to bend the sheet at specific angles, shaping the part according to the desired design.
- Drawing: a die is used to deform the sheet and create cavities or protrusions in the part, forming features like recesses, ribs, or grooves.
- Punching: holes or cuts are made in the sheet using punches and dies, allowing for the insertion of screws, rivets, or other components.
Design and operation of metal stampings
In this technique, the metal sheet is placed in a specialized press that performs a series of sequential operations. During each press cycle, parts are formed, cut, bent, drawn, and punched in a single pass.
This is achieved using a progressive die, which contains multiple workstations, each designed to perform a specific operation on the sheet. The continuous advancement of the sheet along the stations enables the efficient and high-precision production of complex parts.
Applications and industries using progressive stamping
Progressive stamping is used in numerous applications and sectors thanks to its strong capacity to produce complex metal parts efficiently and cost-effectively. From the manufacturing of automotive components to the production of appliances and electronic devices, this manufacturing technique is essential in many industries.
- Automotive: used to manufacture parts such as body panels, chassis components, engine mounts, and internal vehicle parts.
- Home appliances: used to produce metal parts for washing machines, dryers, refrigerators, ovens, and other household appliances.
- Electronics: applied in the production of device casings, connectors, printed circuit board supports, and other metal components used in electronics.
- Aerospace: used to manufacture components for aircraft and rockets, including structural parts, brackets, and system components.
These are just a few of the applications and industries where this manufacturing method plays a vital role in producing high-quality, precision metal parts.
Advantages of progressive stamping in manufacturing
