Precision EDM for the most demanding details
Electrical discharge machining (sinker EDM) is a specialized material-removal technology using controlled electrical discharges. Because conventional CNC milling reaches physical tool limits with deep cavities and sharp internal corners, sinker EDM is an ideal choice for producing inserts for injection molds, punches, and dies.
Precise shape transfer via an electrode
We pre-machine a precise shaped electrode from copper or graphite, then “burn” its shape into the workpiece with micron-level accuracy. Material hardness is not an obstacle; we routinely sink features into fully hardened tool steels.
End-to-end manufacturing chain
At PINP, EDM is not an isolated service. We integrate it seamlessly into the process—we first rough-mill the part, harden it, and then use sinker EDM to finish the finest details.

Wire EDM uses a tensioned wire to cut through-profiles. Sinker EDM uses a machined 3D electrode to produce blind cavities and very fine surface finishes.
