As you can see in the photo above, the pipe on the bottom has been significantly crimped by a conventional press, while the Mandrel-bent pipe on the top retains a consistent diameter through each bend.

What is Mandrel Tube Bending?

The key difference between a Mandrel Bending Machine and a conventional bending press, is that the conventional press cannot bend pipe without collapsing or crimping the tube to some extent. While this may be acceptable for regular automotive exhaust systems, any reduction in pipe diameter will create a restriction which, in turn, will reduce power, performance and economy.

To overcome this, Beaudesert Exhaust have invested in CNC Mandrel Bending Machines in order to bend pipe without any crimping. This means that all of Beaudesert Exhaust's Systems provide increased airflow into, and out of, your engine providing for maximum power, performance and economy.

The CNC mandrel bending machines use a pair of half-round steel dies to hydraulically bend the outside of the pipe. The difference is that the mandrel bender inserts an articulated steel "stiffener" (the mandrel) inside the pipe to keep it from collapsing. It's much like a series of three or four metal donuts held together by a ball-and-socket and spring arrangement and is just a hair smaller in diameter than the inner diameter of the pipe.
