A novel device and method for the injection and molding of a body of elastomeric composition within a mold cavity, around a core member and against the prepared surface of a test substrate, such as a ceramic or metallic disk, at the base of the mold cavity. The molded elastomeric composition is molded as an axial-symmetrical frustro-conical body which tapers down to a uniformly thin layer between the test substrate surface and the flat undersurface of the core member, and the core member supporting the molded elastomeric body bonded to the test substrate are separable from the mold cavity for attachment to a conventional tension test machine for measuring the interfacial bond strength between the elastomer and the prepared surface of the test substrate.
