A type of roll bending tube processing technology has its limitations, as it is not suitable for the production of small-radius bends. It is generally used for thin-walled tube materials with large angles. In fact, this method involves bending using three roller edge tube components. Among these rollers, there are three rotating shafts and two driven wheels. The roller wheels commonly used in tube bending have a running surface that matches the tube material's cross-sectional design. During bending, various angles can be achieved by adjusting the distance between the main and driven roller wheels. Therefore, this method is particularly advantageous when used to bend annular or helical-shaped tube materials.

The second method is called bending. This production and processing technique boasts significant advantages both in usage and manufacturing. It is not only convenient to use but also efficient in production processing, commonly employed for bending tubular materials with straight sections or pipes, etc. Simply put, it involves bending stainless steel wire materials using the mold's function on a four-column hydraulic press, which is a very common bending processing method.

Three types involve beating around the bush. Due to their wide application, they can be further categorized into two distinct production methods in the market: handcrafted bending and CNC bending machines. The former does not require specialized equipment, offering a low cost but demanding high work standards with low productivity. Today, bending machines are commonly used. CNC bending machines, on the other hand, come in core bending and coreless bending variations.
