According to the different binder, the PCD module can be divided into cobalt base and silicon base two kinds. Cobalt based PCD Mold Core contains metal binder, has the good machinability, may use the EDM, the laser, the ultrasonic and so on processing, but the metal cobalt existence causes the diamond at the high temperature to be prone to graphitization, therefore this kind of mold core is suitable under 650 degrees Celsius condition processing and uses.
