Fineblanking, Diffusion Bonding, and Testing of Fluidic Laminates.
Abstract
Two manufacturing processes that show promise of improving the performance of laminated aluminum fluidic components are fineblanking and semi-solid-state diffusion bonding. A representative three-stage amplifier design was used as the basis for evaluating these processes. Amplifier and manifold laminates were produced by fineblanking, and amplifier modules were fabricated by diffusion bonding of the fineblanked laminates. Functional (pressure gain) tests conducted before and after bonding showed gain changes in all bonded modules, but the number of modules bonded was too small to permit determination of any pattern. Surface and dimensional quality of the fineblanked laminates was excellent in laminate thicknesses up to 0.51 mm for amplifier elements, and up to 3.18 mm thickness for manifold laminates. Overall quality was judged to be equivalent to that normally achieved by the photochemical etching process. Due primarily to high initial die cost, fineblanking is economically feasible only where large production quantities are required; diffusion bonding, at the present state-of-the-art, relies heavily on human operator technique and appears to need further development before it can be considered a viable production process.
