Sinker EDM machines are essential in mold and die making, aerospace component manufacturing, automotive tooling, and tool and die shops, wherever hardened or hard-to-machine materials require precise cavity and detail work.

Sinker EDM uses a shaped electrode to erode a cavity into a workpiece, ideal for die sinking and mold detail work. Wire EDM uses a thin traveling wire to cut through material, better suited for cutting profiles, slots, and through-features.
