PROBLEM TO BE SOLVED: To provide a die-casting machine which can cope with ultra-high speed injection (in the case of being the faster than 2.5 m/sec injection speed). SOLUTION: The maximum injection speed is faster than 2.5 m/sec in an injection apparatus of the die-casting machine, and a plunger rod and an injection piston, etc., are made of titanium-aluminum base light alloy. Further, the above titanium-aluminum base light alloy contains 2.5-8.35 wt.% aluminum. COPYRIGHT: (C)2004,JPO&NCIPI
