Die Sinking EDM, or plunge EDM, is a specialized process used to create intricate cavities, molds, and forms in hard metals. It uses an electrode to erode the material with electrical discharges, making it ideal for producing detailed features in hard materials like tool steels and tungsten carbide. Commonly used in automotive, aerospace, and mold-making industries, it allows for high-precision machining of complex shapes, tight tolerances, and fine details. Applications include mold making, die-casting molds, stamping dies, and parts for electronic, jewelry, and medical industries.
