Stampaggio metalli
Il settore industriale si affida ai fornitori di stampaggio dei metalli per creare diversi componenti per i loro macchinari e attrezzature o per aiutarli in processi operativi specifici. È veloce, affidabile, ed efficace per produrre forme complesse dalla lamiera.
L'accessibilità economica, qualità, e la velocità di produzione offerta dallo stampaggio dei metalli sono le ragioni principali per cui molte industrie scelgono questo processo per sviluppare parti e prodotti durevoli.
La storia dello stampaggio dei metalli
Lo stampaggio dei metalli si è evoluto dall'uso di un ferro o di un martello per creare forme sulle monete fino allo sviluppo di un torchio a vite nel XIV secolo. Oggi, questa tecnica di formatura dei metalli viene eseguita utilizzando attrezzature e processi più moderni.
Cos'è lo stampaggio dei metalli?
Stampaggio metalli noto anche come stampaggio lamiera, prevede l'utilizzo di una pressa e di stampi (utensileria) per trasformare la lamiera nella forma o nel disegno che preferisci. La superficie dello stampo e l'utensile utilizzano diverse tecniche per lavorare il metallo fino a ottenere la forma o la forma desiderata.
La matrice si riferisce agli strumenti utilizzati per sviluppare la forma finale di un pezzo. Questo processo di produzione è in grado di supportare progetti o requisiti di produzione di parti metalliche di volume medio-alto a prezzi accessibili.
Tecniche di stampaggio dei metalli
Il basso costo, ad alta velocità, I processi di produzione ad alta precisione associati allo stampaggio dei metalli comportano l'applicazione di diverse tecniche, ad esempio:
Soppressione
The blanking process involves the removal of a workpiece from primary material to create the desired form. Unlike punching, the removed workpiece becomes the desired shape or blank.
Punching
This technique refers to the use of a die and a punch to cut sheet metal into the required form. During punching, the punch enters the material attached to the die and dispels pieces of metal to create the desired form in the remaining workpiece.
Coining
This technique involves the placement of the material between a die and a press or punch. The material is squeezed with extreme force during the press stroke to generate fine features and tolerances on the surfaces of parts.
Piegatura
Bending refers to processes that form sheet metal into desired bent shapes, which are generally the L, U, or V-shapes. The bending process is applied above the material’s yield point and around a single axis to form the desired shape.
Flanging
The flanging process involves the use of a die and a flange or flares produced by a flanging tooling section on a workpiece. The flange portion of the tooling and die form the desired shape in the workpiece.
Drawing/Forming
The drawing and forming stamping process involves the use of compressive force to form sheet metal into a cavity or produce a shaped form by wrapping the workpiece over the desired shape in the die.
Embossing
The embossing process involves the use of a die and a pressing or stamping machine to apply the shaped die onto the material. The embossed pattern or designed form is then imprinted on the workpiece.
Curling
The curling process is used to eliminate sharp edges or form sharp edges into hollow rings according to a specific design. Once performed, curling also increases the moment of inertia at the curled end of the workpiece.
Piercing
The piercing process involves punching or cutting out holes of closed shapes in a workpiece. The punched-out portion is discarded and the pierced pattern forms the end-use part.
These diverse metal stamping techniques are done individually and can be combined or done in multiple operations to form the intricate parts a project requires. The peculiarities of individual projects are the major determining factors when choosing which metal stamping techniques to apply.
For example, a simple bent design can be developed using bending while intricate tooling sections may combine flanging and piercing or any one of the other techniques outlined above.

The different types of metal stamping utilize the diverse techniques that are applied to produce a finished part with high quality standards. There are three major types of metal stamping, and they are – Progressive die stamping, Deep draw stamping, and Fourslide stamping.
Progressive die stamping
With progressive stamping (also referred to as prog die stamping), we move strip metal through a progressive stamping press, where it passes from one station to the next. Each station performs a specific function, including forming, punching, flessione, and cutting the metal.
In most cases, progressive stamping requires the use of multiple stations or stages, especially when a project involves complex parts. Progressive stamping offers the advantages of a quick turnaround and the creation of repeated, uniform pieces. It also has the lowest labor cost for each stamping type.
Deep draw stamping
Deep drawing is a technique that uses a punch to feed a blank into a die. It works best for projects in which a customer needs extreme depths on the part shape. Generally, parts with sweeping and deep shapes are used in the Automotive and Aerospace Industries. Deep drawing uses less raw material than other stamping processes. It also works well for producing less-complicated pieces at high volume.
Fourslide stamping
Fourslide stamping is a metalworking process that simplifies the creation of complex parts. It uses four tools that each bend the metal into the required shape simultaneously. While fourslide stamping doesn’t create pieces with as much uniformity as progressive stamping, it makes changing or adjusting the design easier when a project requires many parts with different bends.
Which metal stamping process is right for your project?
Metal stamping is a popular manufacturing process for developing parts with tight tolerances using sheet metal, like steel, rame, acciaio inossidabile, and aluminum. You can take advantage of metal stamping to manufacture products across diverse industries such as:
- Automotive
- Agricultural parts
- Aerospace
- Electronics
- Home appliances
- Lighting
- Healthcare
- Defense
- Telecommunications

A few factors play important roles in determining the correct metal stamping process and techniques to use. These factors include the manufacturing budget, shape and size of the manufactured part, production speed, qualità, and production volume. Types of Metal Stamping:
Progressive Stamping:
For producing complex patterns in the automotive, aerospace, defense, and home-appliance industries.
Used for low to large-volume manufacturing.
Fourslide Stamping:
For producing domestic or home-appliance items, agricultural parts, and spare parts.
Supports mid to large-volume production runs.
Deep Draw Stamping:
Uses less material than the others and is applied in the automotive, aerospace, and home-appliance industries.
Supports low to mid-volume production runs.
