摘要

Production of an element made from polycrystalline diamond (4) comprises molding a substrate (2) with a surface complementary to a surface of the element; coating with polycrystalline diamond using CVD; and removing from the mold. The diamond is finished either before or after being removed from the mold. The substrate is machine cut to form the complementary molded product. Preferred Features: The substrate is made from silicon or molybdenum. The substrate is molded by grinding.
