How do bending forces and mandrel functions factor into tube bending?

The skills possessed by our team members allow us to create some of the best tubing products in the industry. Utilised for all sorts of applications, these tubes are immensely versatile. Fortunately, our tube bending services are just as diverse.

Several different bending techniques are available. They include the likes of roll, ram, press, and draw bending. Despite the differing approaches, every one of them hinges on the same basal notions. Bending principles make up the premise for the majority of processes we see today. These fundamentals converge in a multitude of ways, which can influence the usefulness of tube manufacturing.

Always consider bending force

Bending force is one of the aforementioned principles. While tubes are being bent, the outer wall at the bend’s point starts to thin and stretch out. Concurrently, the matching inner work piece section becomes more compressed and thicker. For a rounded and smooth bend, you must keep these degrees of physical malformation in check.

Mandrel function is another important principle that you need to know about. During particular scenarios, the tubing work piece won’t meet the necessary criteria. Consequently, you can’t shape it correctly with a rudimentary die set contraption. Once the wall factor measurement begins to expand and tighten from the exterior wall thinning, so too will the bend radius. This heightens the likelihood of obtaining a flattened bend. A mandrel can account for this vulnerability. Mandrels are tools that are secured to a tube’s interior at the bending point and offer support from there.

At Multiform Tubes, to acquire supreme results, we make use of advanced machinery for our tube bending services. Aside from our standard work, we also supply clients with advice and guidance whenever they request it. Consequently, we can help people to get the right products for their needs.
