Large-Extrusion-Press Operation and Production Problems

Giant presses now under construction or planned in this country will enlarge by severalfold the size of light-metal shapes and tubes that may be extruded. The operation of the new presses will present many production problems, both predicted and unpredicted, but at the same time will permit the extrusion of large or intricate shapes which lead to economy and versatility in aircraft construction. A review of operating techniques and problems associated with present large extrusion presses points out some of the expected problems and emphasizes the increased scope of the extrusion process to provide metal shapes designed for the utmost usefulness.
