Electrical Discharge Machining (EDM)

High-fidelity surface finishing for stamping dies

Our electrical discharge machining service excels in creating intricate details and high surface fidelity required for heavy-gauge metal stamping. We specialize in machining hardened materials with minimal thermal distortion, ensuring tight tolerances and repeatable results. This process is ideal for complex mold cavities and components where conventional milling cannot achieve the required precision.

What our clients say

Feedback from heavy manufacturing partners on precision and durability.
