Steps in EDM Wire Manufacturing Process

1. Copper cathode, Special high-grade Zinc and Master alloys.
2. Induction Melting
3. Alloy Forming verified through Spectrum Analysis.
4. Dispatch
5. Packing under controlled environment.
6. Total Quality Assurance
7. Inline Annealing, Spooling, and Change over
8. Consecutive Automatic Operations in Drawing Process.

Electrolytic Zinc Plated Brass EDM Wires

Zinc-coated wires manufactured on European Technology consists of brass wire electroplated with high purity zinc. the high plating accuracy realizes faster cutting speed and provides a better surface finish on the work piece.


  1. High purity uniform zinc layer
  2. Impurities are kept to the minimum, thus preventing deterioration of performance
  3. The discharge is stable and free of irregularities
  4. High cutting rates
  5. Reduced tendency of wire breakage and copper deposit
  6. 6. Excellent value for money

High quality diffused EDM Wires for High Speed EDM Machines. This diffused EDM wires are coated and diffused to give better cutting speed, up to 25% then plain wires.
