The main types of sheet metal bending include air bending, bottom bending, stamping bending, roll bending, and V-bending. Air bending uses a punch that doesn’t make contact with the bottom die, offering flexibility in the bending angle. Bottom bending ensures greater precision by pressing the material into the die for more accurate angles. Stamping bending applies force to the metal to create exact bends. Roll bending is ideal for forming curves or circles, and V-bending uses a V-shaped die to efficiently achieve various angles. The choice of method depends on the material, thickness, and desired angle to deliver optimal results.

Aluminum alloy 3003 is generally considered one of the best choices for bending. It offers a balanced combination of average strength, excellent cold workability, and high elongation. Additionally, it provides a significant difference between its yield and tensile strength, making it ideal for most bending applications.

At Shengwo, we utilize advanced CNC bending technology to guarantee the precision and consistency of each part. Our process includes thorough inspections at various stages to verify dimensions and alignment. We also adhere to strict industry standards to ensure that every bent component is durable and reliable for its intended application.

The most commonly used metal bending technologies include press brake bending, roll bending, and tube bending. Each method is suited to specific applications depending on the material and desired bend characteristics.

The minimum bend radius is typically determined based on the thickness of the sheet metal (denoted as t). We recommend a minimum bend radius of 1t for all sheet metal parts, meaning the smallest radius of any bend should be at least equal to the thickness of the sheet.

The duration of the bending process varies depending on factors such as material type, thickness, and design complexity. Most projects are completed within a few hours to a few days, depending on these variables.
