Mold EDM Machining

Mold EDM (Spark Erosion) Services

Specialized in EDM sinker machining for complex mold cavities, cores, and intricate details that are difficult to achieve with conventional CNC. Using graphite and copper electrodes, we create deep ribs, thin walls, and fine textures with high precision.

Complex Geometry & Deep Cavities

Capable of machining hard materials (HRC 50+) without inducing mechanical stress. Ideal for deep cavity sinking, narrow slots, and undercuts in mold steel, ensuring the exact replication of electrode geometry onto the mold surface.

Fine Surface Finishing

Achieve various surface finishes directly from the EDM process, reducing the need for extensive hand polishing. We control spark parameters to minimize the heat-affected zone (HAZ) and white layer, ensuring the structural integrity of the mold.

Precision & Accuracy

Maintain tight tolerances and fine detail accuracy for critical mold features. Our EDM process ensures excellent electrode wear compensation and precise depth control, which is vital for parting lines and shut-off surfaces.

Integration with Mold Making

Seamlessly integrated with our CNC and polishing departments. Post-EDM inspection verifies dimensions and surface quality before the mold moves to the assembly stage, ensuring a perfect fit for the final plastic parts.
