Abstract: A molding tool (10) has a body (20) that can be inserted into a cavity (62) of a component (12) for introducing molding material (72) to form a mold of one or more internal surfaces (60) defining the cavity (62). The molding material (72) is at least partially cured with the tool (10) in place so that the mold (80) and tool (10) are removed from the cavity (62) as a single unit. The tool (10) includes a passage (34) for introducing the molding material (72) into the cavity (62). A pressure device, such as a plunger (50), may be used to force the molding material (72) through the passage (34) and into the cavity (62). The tool (10) also serves to support the mold (80) on a fixture or other structure used to analyze the mold (80) to verify characteristics of the form, such as, for example, an optical comparator.
