EDM (Electrical Discharge Machining) is a vital process in die and mould manufacturing, especially for machining complex internal cavities, tight-tolerance features, and hard-to-machine materials like tool steel and carbide. EDM enables manufacturers to achieve ultra-precise detailing, mirror-like surface finishes, and create intricate geometries that are difficult or impossible with traditional milling or turning. It is particularly useful in producing injection moulds, die inserts, and fine-detail tooling, making it indispensable for high-precision industries like automotive, aerospace, and medical device manufacturing
