Diamond Sintering Die

Diamond Sintering Die

diamond sintering die that made from high density graphite material


Diamond sintering die is made of graphite material, has excellent electric & thermal conductivity.

Graphite sintering die that made of high quality graphite mould has below property in pressure sintering of diamond tools:

  1. High density, excellent physical performance.
  2. Resistance to high temperature, excellent thermal conductivity.
  3. Resistance to corrsion of acid and alkali.
  4. Long service life.
  5. If pressure temperature increase to 1350 – 1450℃, required unit pressure will be reduced to 67-100 kgf/cm (1/10 pressure of cold press).
  6. Forcing and heating could be proceed in one procedure, compact sintering body could be obtained in short time.
