Analysis of material properties of polycrystalline diamond die

Polycrystalline diamond (PCD) die material is made by connecting non-oriented diamond crystals together. The synthetic mass is sintered under very high pressure and temperature in the presence of bonded metal catalysts.

Polycrystalline diamond (PCD) combines hardness, wear resistance, strength, toughness and high thermal conductivity. These unique characteristics make it a high performance material customized in many materials drawings. It is also suitable for many other applications, combining precision and wear resistance.

Polycrystalline diamond is used to make our diamond dies, either as a PCD blank itself (self supporting), or as a PCD blank with a carbide ring (tungsten carbide die supporting). A heat stable blank (without a metal-bonded catalyst) can also be used at high temperatures or without electrical conduction.

The materials we use, i.e. natural crystal diamonds, synthetic monocrystalline or polycrystalline diamonds, will depend on the application, the conditions of use of the moulds, the technical and economic requirements of our customers.


In the mold production, we use the leading brand of polycrystalline diamond, its quality has been proven for many years.
At the same time, our methods and r&d departments regularly check and test the quality of the various polycrystalline diamonds we use, enabling us to guarantee the consistent reliability of our tools.
