Mandrel Links & Balls

Mandrel Links & Balls are important components in precision tube bending, particularly when manufacturers need to maintain tube shape during tight-radius or thin-wall bending. A mandrel supports the internal diameter of the tube while the tube is being formed, helping minimise deformation, flattening and unwanted wrinkling.

Delahenty Machinery supplies mandrel solutions for different tube materials, diameters, wall thicknesses and bending requirements. Available configurations include standard ball mandrels, close-pitch and ultra-close-pitch mandrels, chain-style mandrels, plug and spoon mandrels, as well as specialised options for square, rectangular and oval tubing.

Close-pitch mandrels are particularly useful for applications involving thin-wall tubes and tighter bend radii, where internal support is critical to achieving an acceptable finished profile. Mandrel components can also be manufactured from materials such as tool steel and aluminium bronze, depending on the application.

Selecting the correct mandrel configuration is closely connected to the bend radius, tube dimensions, material characteristics and required surface finish. Delahenty’s tooling specialists can assist manufacturers in determining the appropriate mandrel arrangement for their bending process.
