アルミニウム合金の重力鋳造における点群金型の適用可能性の検討

The mold used in aluminum alloy casting has a high cost and a long production period. Therefore, as a new shaping method for casting, a pin screen mold was proposed in this study. The pin screen mold, which has a large number of pins with tips, can transfer arbitrary shapes by changing the distance between pins and height of pins. It was found that when the distance between the pins was small, the molten metal could be cast without leaking through the gaps between the pins. When the distance between the pins was large, the molten metal could be cast by lowering the temperature of the molten metal to form a semi-solid state. The pin screen mold could be used repeatedly, which is expected to reduce the cost of aluminum alloy casting.
