What is heat induction bending?

Heat induction bending is a process that uses heat to soften a section of a metal pipe or tube, allowing it to be bent into a desired shape. The process uses an induction heating coil to heat a specific section of the pipe or tube, and then a bending die is used to shape the metal while it is still hot. This process is commonly used in the manufacturing of pipes, tubes, and other metal products.

The advantages of heat induction bending over traditional methods include more precise control over the heating process, which allows for more accurate bending, and the ability to bend a wider range of materials, including stainless steel and aluminum. Additionally, because the metal is heated locally, there is less thermal stress on the material, reducing the risk of cracking or other damage during the bending process.

The basic process of induction bending include:

Pre-heating: Induction coil pass through the area of pipe or tube that required to be bend, this will heat the metal to a specific temperature to make it suitable for bending.

Bending: After pre-heating, the metal is bent using a bending die. The die is designed to match the desired shape and size of the final product.

Cooling: After bending, the metal is cooled to solidify its new shape.

There are several variations of heat induction bending depending on the size of the pipe and the precision required, such as cold bending, single-segment bending, and multiple-segment bending.

Overall, heat induction bending is widely used in industrial and manufacturing applications such as oil and gas pipelines, automotive and aerospace parts, and many other types of metal products.
