Abstract: A monolithic airflow testing mold suitable for mating with a workpiece includes a platform portion formed from a first material having a first hardness. The mold further includes a workpiece mating portion surrounding by the platform portion. The mating portion includes a support region abutting the platform portion and formed from a second material having a second hardness, and a sealing surface positioned above the support region and formed from a third material having a third hardness. The sealing surface is configured to mate with and extend into a hollow portion of the workpiece. The first hardness is different from at least one of the second and third hardnesses.
