Key Features & Benefits
Discover why our products are trusted by industries worldwide
Ultra-low electrode wear
High-purity tungsten helps minimize electrode loss during spark erosion and supports stable dimensions during extended die-sinking EDM cycles.
High rigidity and precision
Strong resistance to deformation makes pure tungsten suitable for high-tolerance mold details, thin ribs, and demanding finishing work.
3422 C melting point
The ultra-high melting point of tungsten supports severe EDM thermal conditions and repeatable long-cycle machining.
Custom head and profile types
Flat head, cylindrical, stepped, inclined, and special-shaped profiles can be produced from customer drawings or physical samples.
Precision CNC machining
Head thickness, width, diameter, total length, profile geometry, tolerances, and surface condition are controlled for the intended EDM operation.
Drawing-to-delivery support
We support technical review, quotation, production, inspection, and export packing for custom and repeat-order programs.

Pure tungsten EDM electrodes made for difficult mold details
Our custom pure tungsten electrodes are manufactured for die-sinking EDM operations where conventional copper or graphite electrodes may wear too quickly or lose dimensional stability.
High density, high rigidity, and an ultra-high melting point make tungsten a practical choice for complex cavities, deep narrow slots, thin ribs, inclined surfaces, and other precision mold features.
Custom shapes from drawings or physical samples
This is a drawing-based custom product rather than a standard welding electrode.
- Flat-head, cylindrical, stepped, inclined, and special-shaped profiles
- Custom diameter, total length, head thickness, width, and profile geometry
- Technical review against drawings, samples, tolerances, and EDM working conditions
- Trial quantities and repeat-order production support
Precision machining and quality control
Each custom electrode is produced and inspected around the dimensions and working surfaces that matter to the EDM process.
- Material purity and incoming material verification
- Precision CNC machining of the requested profile
- Dimensional tolerance and geometry inspection
- Surface finish and edge-condition review
- Batch identification and packing for delivery
