Metal press braking is a process that bends sheet metal quickly and efficiently using a press brake. The technique does not alter the properties of the metal being worked, producing a versatile semi-finished part for many applications. Whether you need a U-bend for structural profiles or a V-bend for precise angles, press braking gives excellent results on materials such as iron, aluminium, stainless steel and various metal alloys, provided they are sufficiently ductile.
How does metal press braking work?
The press brake, the key machine in this process, applies a controlled force to the sheet, causing a plastic deformation that produces the desired bend. Depending on the design requirements, permanent bends of different angles and radii can be made.
Advantages of press braking and practical applications
- High precision: accurate bends that comply with technical specifications.
- Flexibility: different shapes and angles can be produced (U, V, complex bends).
- Versatile materials: a wide range of metals can be worked (iron, aluminium, steel, alloys).
- Efficiency and speed: a fast process that optimises production times.
- Less waste: precise work that minimises errors and material waste.
- Customisation: bends adapted to each customer’s specific needs.
Thanks to the versatility of press braking, bent sheet metal is used in many sectors, such as household appliances (structural components, outer panels), construction (window and door profiles, roofing elements, gutters, ducting), furniture (table legs, shelving, decorative elements, seating frames) and automotive (body parts, structural reinforcements).
Springback in press braking: a key consideration
Metal bending is a cold-working process that exploits the material’s plasticity. During deformation, the outer fibres of the sheet are stretched while the inner fibres are compressed, creating internal stresses. When bending ends, these stresses tend to make the material partly return to its original shape: this is known as springback. Understanding and managing springback is crucial for accurate bends that meet design specifications. Advanced techniques and modern press brakes can compensate for this effect, ensuring high-quality results.
