In September 2016, we brought both sinker EDM and wire EDM online, completing our precision machining capability stack.
The EDM department was a strategic investment: it allowed us to produce parts with features impossible for conventional milling — deep narrow slots, fine holes (0.1 mm diameter), hardened steel mold inserts, and intricate carbide components.
We installed two sinker EDM machines and one 5-axis wire EDM machine, all from Makino. The EDM team now handles roughly 15% of our workload, primarily for semiconductor equipment parts, mold inserts, and carbide tooling components where milling cannot reach.
