Die-casting apparatus, die-casting method, and diecast article
A die casting method and apparatus are provided, thereby making it possible to produce a thin diecast product that has hitherto been considered impossible to realize, and a diecast product is also provided. A semi-solidified metallic material is formed having particles in solid phase of a particle size less than 30 m, and is thereupon injected into a die. A die casting machine has a sleeve into which a melt of metallic material is poured, and the semi-solidifying material there when it has a certain proportion of solid phase reached is injected into the die with a plunger to which pressure is applied. The melt of metallic material is poured into the sleeve so that the material occupies inside the sleeve at a proportion in vertical cross-sectional area of 30% or less. The particle size in this semi-solid material is held unvaried in a product as diecast.
