CUSTOM TUBE BENDING
Mandrel bending is when a metal mandrel is placed into the tube as it is pulled around a forming die. This retains the shape of the tube throughout the radius of the bend, and prevents any warping.
Multiple bends of different radii and angle can be made on the same length of tube, separated at minimum by the clamp length.
The radius (sharp bend, slow bend) of our custom tube bends is based on the size of the forming die. Various sizes of forming die are available and are listed below in our tooling section.
Custom tube bends allow you to design a part specifically for your needs.
METAL FABRICATION & FINISHING
At Mandrel Bending Tasmania we are skilled metal fabricators.
If your custom bends need polishing, trimming, shortening or adaptation prior to delivery we can help.
Our workshop is set up for all fabrication needs. This includes: welding and purge welding, mill and lathe work, metal finishing and polishing. We can modify your custom mandrel bends into any shape you need.
Check out our motorbike exhaust work at VEREX Tasmania, or below in the gallery to see what we can do!
