    Abstract: PURPOSE: An injection sleeve for die casting is provided to protect sleeve from thermal impact and load impact of molten metal on a specific spot of the sleeve. CONSTITUTION: An injection sleeve for die casting comprises a sleeve(10), a protective layer(20), and a friction reducing unit. The sleeve has a pouring gate(11) and is equipped with an injection plunger(1) inside. The protective layer shields the inner wall of the sleeve. The protective layer is made of material having high melting point, high hardness, and high thermal conductivity. The friction reducing unit minimizes rubbing between the protective layer and the injection plunger. The friction reducing unit comprises a micro slit formed on the surface of the protective layer.

    Abstract: PURPOSE: An injection sleeve for die casting is provided to reduce frictional force of a protective layer by reducing a valid surface area of the protective layer using minute slits. CONSTITUTION: An injection sleeve for die casting is composed of a sleeve(10), a protective layer(20), and a friction reducing unit. The friction reducing unit comprises minute slits. The minute slits are formed on the surface of the protective layer and reduce a valid surface area of the protective layer. The friction reducing unit is formed in a scratch-shape and is arranged crossing with the surface of the protective layer.

    Abstract: PURPOSE: A die casting method is provided to prevent interface or uneven texture density inside the thick portion of a cast product. CONSTITUTION: A die casting method comprises the steps of: assembling a mold(70) of a sectional structure, creating a vacuum of 18mmhg~22mmhg in a mold cavity(72) and a sub cavity(74), injecting molten metal at high pressure into the mold and sub cavities, leaving the molten metal in the mold for 1~5 seconds to change the molten metal into a semi-solid, raising the density of the molten metal in the mold cavity, reclaiming hollows such as holes or cavitations of the mold cavity, and leaving the molten metal in the mold and sub cavities for several seconds in order to complete a metal cast product.
