New High-Pressure Hydroform Tool Design Reduces Springback in Ultra-High Strength Steels

New High-Pressure Hydroform Tool Design Reduces Springback in Ultra-High Strength Steels,” SAE Technical Paper 2019-01-1084. Flexform™ is a high-pressure hydroforming technique using a flexible rubber diaphragm between the liquid pressure medium and the sheet metal. No seal is thus needed between the metal sheet and the pressure medium.
