The press brake suitable for the air bending process is usually a hydraulic press brake or electric press brake. These two types of press brakes can exert appropriate pressure on the metal sheet to bend the material into the required shape. Air bending is achieved by air pressure exerted on the metal sheet. The hydraulic press brake utilizes the hydraulic system to control the pressure and bending angle, while the electric press brake uses an electric-driven system. These press brakes are used to generate metal components and structures because they can offer precise control and high-quality bending.
