Mandrel Tube Benders

Bossray Mandrel Tube Benders are used to bend metal tubes or pipes accurately and without deforming the inner surface of the tube. It uses ball mandrels which is a solid rod and balls inserted into the tube during the bending process to prevent it from collapsing or wrinkling. This results in smooth and precise bends for various applications such as Automobile, Industrial vehicles, Metal fabrications and Construction etc.

Mandrel tube benders are specific type of tube bending machines. It is so called only because it uses a mandrel to maintain the diameter of the tube being bent. Normally, when a tube is bent, it loses internal diameter and can wrinkle or even break. The mandrel, inserted into the tube at the point of the bend, keeps a constant diameter at the bend and reduces deformation. While there are several different types of mandrels, the most common includes a straight rod attached to several flexible balls. The mandrel must match the diameter of the tube or pipe to be bent.
