Wire EDM — 2D Profile Cutting
2D contour cutting of hardened tool steel, carbide, titanium and stainless by wire erosion. No mechanical force on workpiece.
Wire Ø0.1–0.3mm · Tolerance: ±0.003mm · Taper cutting available
Wire EDM — Taper Cutting
Angled wire EDM cuts for die inserts, punches and extrusion dies requiring taper relief.
Taper angle: ±15° · Hardened tool steel, carbide
Wire EDM — Stack Cutting
Multiple thin workpieces stacked and cut simultaneously. Efficient for production of identical profiles.
Reduces per-part cost on repetitive shapes
Wire EDM — Fine Finishing
Multi-pass skim cutting for surface finish Ra 0.2–0.4μm. Dimensional accuracy ±0.002mm.
For gauging, precision inserts and mold cavities

Sinker EDM — Cavity Sinking
3D cavity shapes sunk into hardened steel using a graphite or copper electrode. For mold cavities and die sinking.
Electrode: graphite or copper · Surface Ra 0.4–3.2μm
Small Hole EDM Drilling
Precision small-hole EDM for start holes, cooling holes and through-holes in hardened materials.
Hole Ø0.3–3mm · Depth: up to 100× diameter
EDM Surface Texturing
Controlled EDM texturing of mold faces for matt or stippled surface finish on plastic parts.
Texture depth and pattern to specification
