Wolfram carbide EDM blocks for stamping molds and stamping dies

  1. Raw material selection: High quality tungsten carbide powder is preferred. 100% virgin material.
  2. Imported German PVA sintering furnace. HIP sintering. Which can keep wolfram carbide edm blocks in high density, High wear resistance, excellent resists electrochemical corrosion high-performance.
  3. Professional engineers and quality inspection teams ensure product process inspection and acceptance inspection to ensure stable product quality and prevent unqualified products from being shipped.
  4. More than 40 years of manufacturing experience.
  5. The wolfram carbide edm blocks performance and service life are close to 90-97% of Guhringg, Ceratizitt, Boehleritt and Kennametall.
  6.  Wolfram carbide edm blocks are suitable for Impacting punches, Coining dies, Forming dies, Can die punches, Swaging dies, Cold forming, Back extrusion punches & dies, high-impact extrusion dies.
