である。- Aluminum was used for the mandrel in this example because it was eluted with NaOH in the final layer, but it was necessary to remove the mandrel without having a negative effect on the sprayed metal.
10,000 F, example ri Mg, g4. Pb alloy, Cu may be used, and the removal force method is not limited to NaOH but HN 03
eHot, HF, and HNO3+HF mixed liquids can also be used, and even a single physical one is fine. The outer shape and dimensions of this mandrel 1 are made to match the inner shape and dimensions of the finally required metal molded body. Note that FIG. 2 (1) CB) is a sectional view taken along line AA' in FIG. 2 (1) (-).
