Mandrel bent意思

"Mandrel bent" is a term used in metalworking, particularly in the context of bending tubing or piping. It refers to a specific method of bending that results in a smooth, consistent radius and maintains the structural integrity of the material being bent.

In mandrel bending, a mandrel (a rod or form) is placed inside the tube or pipe as it is being bent. The mandrel supports the inside of the tube or pipe throughout the bending process, preventing the material from collapsing or wrinkling. This ensures that the finished product has a clean, uninterrupted curve with no dents or imperfections.

Mandrel bending is often used in applications where a precise and uniform bend is required, such as in the automotive industry for exhaust systems, in construction for HVAC ductwork, or in the manufacturing of custom piping for various industries. It is particularly useful for materials that are prone to distortion or for larger diameter tubes where a smooth bend is essential.
