EDM in Mold Making: Sinker vs Wire-Cut

Electrical Discharge Machining (EDM) is essential for creating complex cavity details, sharp internal corners, and deep ribs that cannot be milled. Sinker EDM uses a shaped electrode to create a cavity impression. It is ideal for complex 3D cavity shapes and texture applications. Wire-cut EDM uses a traveling wire to cut through the workpiece. It excels at tight-tolerance through-cuts, such as ejector pin holes and core inserts. Yinzan Technology uses both EDM technologies in-house, ensuring full control over quality and delivery timing.
