Mandrel Tube Bender Process Description

What does it do? How can I use it? Why will it help me?

A mandrel tube bender is a specific type of tube bending machine. 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.

Process Description: How does it work?

A mandrel tube bender works lust like a normal tube bender, except a mandrel is inserted into the tube and placed at the point of the bend. 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.

After the mandrel is inserted, the pressure and wiper dies push the tube against the former die to the desired angle. Usually this is up to 1.5 times the diameter of the tube. Mandrel tube benders do not allow rebending as other tube benders do.
