Bellows Manufacturing






Bellows Manufacturing

Megaflexon manufactures bellows using an expanding mandrel (punch forming) method followed by a finish rolling. A rectangular sheet is sheared and rolled into a tube. The tube is welded using an auto flat-bed welder with no filler metal added. 


The longitudinal seam weld is then planished back down to the base material thickness.  Dye penetrant, X-ray, or air testing is performed at this stage. After testing, the convolutions are punched individually drawing material from the top and bottom of the tube.  The drawing process eliminates any possible thinning in the bellows material. Then, re-rolling process and then trimming process will follow.
In addition to this, Megaflexon manufactures bellows using a variety of machines, including hydraulic forming machines and automatic hydraulic forming machines.
