Description
Matrix body bits are manufactured by mold process. The tungsten carbide and binder materials are arranged into the mold. The mold get placed into the furnace for certain period of time and materials are cooled to certain temperature. The mold later cooled down and broken to remove the unfinished matrix bit.
