The heat transfer section is externally provided with a plurality of receiving grooves for correspondingly connecting with a plurality of radiating fins. The LED heat sink manufacturing method includes the steps of molding a main body using a half-molten metal material and cooling the main body, so that the cooled main body is connected with a plurality of radiating fins to form an integral unit. With the LED heat sink manufacturing method, it is able to manufacture an LED heat sink having a relatively complicated radiating fin structure or being formed of two or more types of materials, and to largely reduce the time, labor and material costs of the LED heat sink.

  • Patent number: 8672018
    Abstract: A cylinder head is formed by positioning a clad preform including a first and second layer in a casting die cavity with the second layer in communication with the die cavity and the first layer facing outwardly to define a combustion surface. Molten material provided to the die cavity is solidified to form a cast portion metallurgically bonded to the second layer. An aperture of the preform forms a port in fluid communication with a passage of the cast portion. A plurality of dome-shaped preforms may define the combustion chambers of a cylinder head formed by the method. The preform may define a cylinder head face. The first layer may be a steel-based layer, and the second layer and cast portion may be aluminum-based, such that the first layer and combustion surface has higher thermal fatigue strength relative to the cast portion.

  • Patent number: 8662141
    Abstract: One or more ductile metal inserts may be selectively incorporated into articles of limited ductility, including castings and molded polymers. The inserts are positioned at joint locations for joining of the article to other articles using self-piercing riveting (SPR). The inserts are of suitable ductility, thickness and strength to receive and retain self-piercing rivets and enable a strong riveted joint between the article and a second article. In an embodiment the articles are magnesium alloy castings formed by any of sand casting, die casting and semi-solid metal casting. The chemical composition of the insert may be informed by the anticipated corrosive environment of the joint and the casting temperature of the magnesium alloy. For magnesium alloy castings which may be exposed to corrosive environments, aluminum alloy inserts are preferred.

  • Publication number: 20140057125
    Abstract: A light weight alloy part is molded in a mold containing at least one weldable metal insert, so that portions of portions of the alloy part lap portions of the insert to securely lock the weldable insert to the light weight alloy part. The resulting hybrid part is thus both light weight and weldable to other assemblies and sub-assemblies.

  • Patent number: 8568120
    Abstract: A tire vulcanization mold manufacturing method can manufacture a tire vulcanization mold having an exhaust mechanism capable of ensuring sufficient exhaust with fewer processing steps. When a mold having a surface of a gypsum mold transferred to the mold is to be manufactured by pouring molten metal onto the surface of the gypsum mold and solidifying the molten metal, a tubular body having a slit allowing hollow inside to communicate with the outside is disposed in such a way that the slit is brought into contact with the surface of the gypsum mold. Thereafter, the molten metal is poured onto the surface of the gypsum mold in such a way that the tubular body is buried in the mold while the slit is exposed on a tire molding surface of the mold.
