Our Sinker EDM service offers the ability to create complex internal cavities, blind slots, deep pockets, and intricate 3D geometries with high repeatability and minimal mechanical stress. Because the process uses a shaped electrode submerged in dielectric fluid, not a cutting tool, we can machine hard materials, deep slots, and complex shapes that are virtually impossible with conventional milling or turning.

Whether you need mold cavities, die inserts, tooling pockets, custom components, or deep internal features, our Sinker EDM cell is engineered to deliver consistent quality, sharp internal corners, and reliable surface integrity.

Choosing our Sinker EDM services means opting for reliable, high-precision cavity making and part production in any conductive material. Our equipment and process controls ensure consistent spark parameters, stable dielectric flow, and precise electrode control for superior part quality. We handle everything from electrode design, roughing and finishing passes, to final washing and inspection, giving you peace of mind and repeatable results. Whether your project involves a single prototype cavity or complex multi-cavity tooling, we provide expert support and craftsmanship.
