The process of this equipment involves forming the branch pipe through a combination of liquid pressure and axial extrusion: ·Fix the tube blank on the dedicated hydraulic press and inject liquid inside. ·The horizontal side cylinders synchronously extrude the billet, reducing its volume and increasing internal pressure. ·The metal material flows along the mold under the action of liquid pressure and side cylinder thrust, eventually expanding the branch pipe ·Features: Capable of one-time forming, with increased wall thickness for the main pipe and shoulder, suitable for materials such as low-carbon steel, stainless steel, copper, and aluminum.
