Metal bending is the process where sheet metal undergoes mechanical deformation to achieve the desired shape or curvature. This method is widely used in metalworking and the production of metal parts and structures. Here are several key aspects of metal bending:

1. Working Principle: Metal bending is carried out using specialized mechanical devices known as bending presses or bending machines. The metal sheet is placed between upper and lower tools, and then pressure is applied to deform the metal according to the specified angle and radius of the bend.

2. Materials: Metal bending can be applied to various metallic materials, including steel, aluminum, stainless steel, brass, and others.

3. Types of Bends: There are several types of metal bending, including V-bending, U-bending, horizontal bending, and more. Each type of bend is suitable for specific constructions and components.

4. Industrial Applications: Metal bending is used to create various metal products, such as casings, frames, doors, window frames, roofs, cladding, and other structural elements.

5. Custom Orders: Metal bending allows for the creation of custom and made-to-order components and structures, making it popular among designers and architects.

6. Precision and Quality Control: Modern bending machines ensure high precision in bending and quality control of manufactured products.

Metal bending is an essential step in the production of metal parts and structures. It provides the capability to create bends and shapes required for various projects and plays a key role in construction, manufacturing, and other industries.
