From [1]

  • 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?
