Mandrel bending is an elemental process in the automobile industry. Particularly, car owners who want to customise their vehicle must invest in this process to fine-tune their exhaust systems, engine cooling accessories, power boost, intakes and other parts. Mandrel bending employs a metal shafts and a few segmented donuts balls. The balls have a smaller circumference compared to that of the pipe you want to bend. During the process, the balls reinforce the inner walls of the pipe so that there is no distortion or damage to the pipe. If you want to hire a fabricator who uses this process, here fundamentals you need at your fingertips:
Mandrel Bends are Strong
For your information, mandrel bends are very strong and durable. If your custom exhaust, inlets and other parts are done using this process, your vehicle will still be able to display its off-road and high way prowess. In fact, some materials become stronger after mandrel bending due to the structural changes that occur in the grain of the metal. Therefore, shrug off any doubts and thoughts from those who try to convince you that mandrel bends are not as strong as welded joints.
Mandrel Bends have A Consistent Diameter
Today, fabricators have gone a long way to improve the quality of mandrel bends. They hold them within consistent ovality specifications and wall thickness by using supporting tools in the interior of the pipe. This ensures that fluids and other materials can flow through the bend with the highest level of efficiency and the least possible resistance. Ideally, you should opt for mandrel bends over pre-made elbows if you are looking to maximise fluid flow in your vehicle's custom-made parts.
Angular Inclination is Precise
Mandrel bends have an added advantage over welds and premade elbow. Mandrel tools are designed to enhance precision when working on angles unlike welded joins and elbows. Welds need a fit, and the addition of soldering metals can distort the angular inclination of the bend.
Cold Bending is Possible
There is a popular belief among many uninformed car owners that all metals have to be post-treated using heat after the mandrel bending process. This is not true, and such myths can make you shy away from the services of a quality professional. Well cold bending is possible for metals such as austenitic steels. There is no need for post-bending treatment, which cuts down the overall costs of fabrication.
