Metal Extrusion

From


 * Process by which metal in plastic state (not molten) is pushed by a ram through a die to obtain desired shape. This is doable well with an induction furnace.



=Questions=


 * How much force is needed to push the billet through the die?
 * Could force be done with a hydraulic cylinder?
 * Does the die need to be heat treated or be made of high temp metal?
 * Can this be used to create hollow shapes like pipes?
 * Is the billet heated separately before being placed in the extruder?
