Tube End Forming Machines | Exhaust Pipe Manufacturing

 

Tube and Pipe End Forming Machines perform Expanding, Reducing, Swaging, Notching and Curling functions on pipe ends. Various machine designs are possible for the automotive, home appliance and fabrication industries based on cycle time and line layout. Our machines can come with up to four forming heads or with one forming head and an integrated leak tester, as per customer requirements. The single or multiple end forming heads move linearly over the workpiece while customized tool sets create the desired end profiles. We supply standard and customized end forming machines to global automotive companies that manufacture exhaust manifolds, exhaust mufflers, driveshafts, and other powertrain components.
