Studies have shown that the performance of structural parts directly affects the safety, reliability, maneuverability, carrying capacity, payload, fuel consumption and other indicators of vehicles. Ultra-high pressure liquid bulging is an advanced manufacturing technology developed to meet the requirements of the above-mentioned industries for high-quality manufacturing of structural parts. The basic principle of forming is to use a tube as a blank, and by applying ultra-high pressure liquid and axial force inside it, press the tube blank into the mold cavity to form it into the desired workpiece.
