Impact Extrusion is commonly used to make collapsible tubes such as toothpaste tubes, cans usually using soft materials such as aluminum, lead, tin. Usually a small shot of solid material is placed in the die and is impacted by a ram, which causes cold flow in the material.  Hydrostatic extrusion is a form of impact extrusion, uses a fluid hydrostatic pressure instead of a mechanical ram. This is useful for making parts out of materials such as Molybdenum, Tungsten that are relatively hard to extrude using normal extrusion methods.  |
