Die Casting

Electrical Discharge Machining (EDM) is a process that removes material in a precise manner from conductive materials with an electrode. This electrode leaves in the workpiece a negative imprint. The process is a bit more intricate: in a tiny gap between the electrode and workpiece, a discharge happens that removes the material via vaporizing or melting.
