Our Strength

Die-sinking EDM is based on the principle of spark erosion. This thermally ablative manufacturing process works by electrically discharging sparks between a shaping electrode and an electrically conductive workpiece, which is surrounded by a dielectric. The electrode has the negative shape of the desired contour of the part to be produced. It is a highly precise, contactless, and shaping process for all electrically conductive materials and is primarily used in tool and mold making.


Die-sinking EDM stands for exceptional precision and the ability to produce complex shape contours and undercuts with narrow tolerance ranges and high surface qualities.

No contact processing

As the electrode does not physically touch the workpiece but works via a spark gap, there is no mechanical stress on the workpieces to be processed.


In wire EDM, complex 3D contours can be created in a wide variety of conductive and hardest materials.
