- 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.
- 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?
