The tube is bent around a fied radius mold and a mandrel is inserted to prevent it from collapsing during the bending process.The tube or tube istightly leaned on the mold and then rotated while the pressure mold moves in a straight line.Ssee our mandrel bending video for a brief oveview.This is the most common form of bending.
Roll forming (rolling)
The pipe is rolled by three rollers to form a larger centerline radius. Please watch our scrolling video for a brief overview.Compression bending
Compression molding is the original technology of bending pipes. Clamp the tube in place and move the pressure die along the radus to form abend, which is the opposite of mandrel bending.This method does not allow the use of mandrels.
