Every example image I've seen of extrusion dies has the billet going in the top and being forced through an opening at the bottom (with an angle leading into the opening, and a relief angle behind it). It would be substantially more convenient for me if I was to create a die where the opening was on the side instead.
What sort of considerations need to be made for that (aside from it not really being machinable on the lathe)? Does this increase the pressure required for extrusion to occur?
