Sarix’s unique EDM milling function enables material removal like a traditional milling process but with electrical discharges. This allows toolmakers to “sculpt” three-dimensional microstructures with micron-level precision, creating complex cavities, channels, and freeform surfaces that conventional machining cannot achieve.

2. Micro Hole Drilling

Sarix provides outstanding micro hole drilling capability, with hole diameters down to Ø20 μm or smaller. This is critical for producing cooling channels, micro nozzles, and microfluidic structures, directly improving mold cooling efficiency, cycle time, and tool lifetime.

3. Complex Structures

Sarix 3D Micro EDM allows for the machining of deep, intricate, and fine structures that are impossible with traditional CNC or grinding, ensuring the highest design freedom for advanced molds.

4. Superior Surface Quality

With excellent surface finish achievable during EDM, Sarix reduces or eliminates the need for additional polishing, shortening overall lead time for mold manufacturing.

5. High Automation

The system is fully compatible with CAD/CAM integration, enabling faster prototyping, shorter mold development cycles, and higher repeatability.

6. Wide Material Compatibility

Sarix is capable of machining hardened steels, tungsten carbide, and high-performance alloys, meeting the full spectrum of requirements for precision molds.
