Core Definition & Manufacturing Process
PCD (Polycrystalline Diamond) die blanks are ultra-hard composite materials engineered by sintering micron-sized diamond particles with cobalt/nickel binders under high-pressure/high-temperature (HPHT) conditions. The resulting structure combines diamond’s intrinsic hardness (8,000–10,000 HV) with the toughness of a metallic matrix, enabling durability in extreme abrasive environments.
