More Information
Summary:The method involves immersing a hollow profile (10) into an immersion container (3) filled with hydraulic fluid, and arranging the hollow profile filled with the fluid in a standard cavity of a molding press (1) using an upper die (15) and a lower die (17). Ends of the hollow profile are guided over sealing spikes during application of inner pressure of the press, and a fluid cushion provided between the cavity and the hollow profile is controllably maintained over a time period till guiding of the ends of the hollow profile over the sealing spikes is completed during discharging of the fluid.
