I'm start-up with an idea for low-volume plastic injection molding.
Keeping costs down, I'll need to do my own die sinking.
I have a CAD/CAM/small CNC mill setup, but with a spindle speed of 4,500rpm max I'm pretty sure I'll get nowhere using 1mm ball-end cutters on a detailed little injection mold, right?
So if CNC EDM is still $50,000 plus, and a High speed mill is getting up there too, what do I do? Get an old 3d pantograph? Or any other suggestions how to do it?
