Abstract
Equipment and method for the rapid and easy extraction of formed metal parts from forming dies while in a press and operating at elevated temperatures. The invention features the controlled supply of streams of air or other inert gas to the interface of the hot surface of the forming die and the formed panel to augment removal so that flaws from removal equipment are minimized for optimized production of high quality parts. High velocity air is discharged through nozzles onto the forming surfaces of hot forming dies to cool the forming die and the part that contract at different rates and pop the part from the surface.
