Mandrel bending service
Infengde do mandrel bending services for local manufacturers and trading companies, with dia. range 1 inch to 5 inches.
The mandrel bends are widely applied in various industrial companies like exhaust pipes, auto parts and other industry products.
Using a mandrel when bending tube is to prevent the tube from flattening and to prevent wrinkles and kinks. But how to achieve this, the mandrel is held in a fixed position, and the tube is pulled over it. The tube stretching process is localized on the outer radius of the bend, and the material is work-hardened to retain its shape and not flatten. Once the material stretching is done on the forward tip of the mandrel. This force, acting on the mandrel tip, supports the inner radius of the bend, holding it firmly into the bend die groove.
