Steam bending is a woodworking technique that involves steaming pieces of wood to make them bendy. One of the most interesting ways of building and constructing with wood is a process called “steam bending”. With centuries to experiment with techniques and methods of building with wood, it’s of little surprise that humans have discovered unique ways to manipulate and build with it. In fact, the oldest standing wooden building is in Japan and dates back to 607 AD.

If all of these parts are functioning correctly and are adequate for the application, then check for drag and make adjustments as needed.Ĭlick here or follow the link below to download a free introduction to tube bending to learn more, or contact us at any time with any questions or comments you may have.Wood is perhaps the oldest building material out there. For tube collapse, it is also useful to ensure that the number of mandrel balls is sufficient for the application. Like most mandrel tubing bending issues, it is always a good idea to check the mandrels position in relation to the tangent. If clamp slip isn’t an issue, the next step is to ensure that there is sufficient push-assist for your set up. Your first step when trouble shooting tube collapse should be to check and see if you’re experiencing clamp slip. Either type of tube collapse can be addressed with the following steps. Tube collapse can occur with or without wrinkling through the bend. The second common issue we will address here is tube collapse. If all else fails, be sure that the material you are attempting to bend is suitable for the application and type of bend you are attempting.
If this fails, you should ensure that the mandrel ball size is correct for your bending specifications and adjust as needed. You can also check the force on the pressure die and pressure die assist.
The second step, if adjusting the mandrel position doesn’t work, is to ensure the free movement of the pressure die. You can try to move the mandrel back from the tangent until the hump goes away. The first step should always be to check the mandrel positioning. Have questions about mandrel bending? Get your free Intro to Tube Bending and learn about the importance of a mandrel to avoiding common bending issues! There are five likely solutions to bends with a hump at the end of the bend and mandrel ball humps. Hump at the End of a Bend and Mandrel Ball Humps For this article, we’ll focus on two common mandrel tubing bender problems and the best ways to troubleshoot solutions for your individual set up and specifications. It is useful whenever beginning a new bending project or run to do a number of sample bends to help pin point adjustments to the machine and tooling. However, like any other bending method, mandrel bending opens up the door to a unique set of issues and problems that can occur. For instance, mandrel bending greatly helps to prevent spring back, which can be excessive without a mandrel.
