Sinker EDM erodes material with controlled electrical discharges, producing shapes impossible with cutting tools — deep ribs, sharp internal corners, thin walls, and features in hardened steel. No cutting force means fragile geometries stay intact.
What We Offer
- Deep ribs & thin walls
- Sharp internal corners
- Hardened & exotic materials
- Electrode-based cavity forming
- Tight, repeatable accuracy
Materials
Hardened tool steels, tungsten carbide, Inconel, titanium, and conductive exotic alloys.
Typical Applications
- Molds & dies
- Turbine & aerospace parts
- Tooling with fine detail
- Fragile geometries
- Prototype cavities
Frequently Asked Questions
What can EDM do that milling cannot?
Sharp internal corners, deep narrow slots, and very hard materials without mechanical stress.
Is EDM good for production?
Yes for low-to-mid volumes and for features that are uneconomical to mill.
