This paper describes the structure of the molds for making polycrystalline diamond compact (PDC) drilling bits. It represents the mold shapes by using the Finite Element technique, and compares the analytical results with available experimental data. Based on the results of Finite Element analysis, some areas of stress concentrations are determined, and modifications made, to the PDC (polycrystalline diamond compact) mold. A displacement plot and several stress contour plots are presented. Techniques of the mold design are discussed.
