A pipe end extrusion forming machine (also called a tube end forming / tube end swaging machine) is a forming device that reshapes the open end of a tube by pressing a die against it under high hydraulic pressure — rather than cutting it, it changes the tube's profile without removing material. The KC-WF42 reshapes a tube end by radial extrusion: flaring it open, reducing (necking) its diameter, or forming a bead / collar, so the end can be joined, sealed or threaded reliably. It uses a crimping head with a clamping die and an ejector tool that the operator fits to the tube size; the operator feeds the tube by hand, the machine forms it under pressure, then the ejector pushes the finished piece out. It is widely used wherever a precise, repeatable tube-end geometry is required for assembly.
