Patent Number Title Of Patent Date Issued
7516772 Method of forming a product of metal-based composite material April 14, 2009
A forming method wherein a billet (31, 66, 77, 87, 107, 128, 136, 144, 153, 77B, 77C) comprising a metal-based composite material (27) prepared by mixing an aluminum alloy (22) and a ceramic (15) is subjected to pressure forming to manufacture a formed article, which comprises carryi
7258209 Brake drum and method for producing the same August 21, 2007
A brake drum includes a ring-shaped drum body, and a friction member secured to the inner circumferential surface of the drum body. Because the drum body is formed of a lightweight Al alloy and the friction member is formed of an Al-base composite material, the brake drum can be reduced
7216746 Brake drum and process for manufacturing the same May 15, 2007
A brake drum has its strength elevated in its disk portion. The brake drum is formed from a composition having ceramics dispersed in a matrix. The disk portion has a high ceramic content and thereby a high strength. The brake drum has a disk portion and a cylindrical portion. The disk po
7201209 Method and apparatus for casting aluminum by casting mold April 10, 2007
An aluminum casting process using a casting mold in which after the cavity (25) is filled with an inert gas, magnesium is introduced into the cavity to have a magnesium layer (58a) deposited on the cavity wall. Then, nitrogen gas is introduced into the cavity to form magnesium nitride
7040376 Method for envelopment casting May 9, 2006
A cast-bonding process includes a magnesium coating step and a magnesium nitride-forming step. The magnesium-coating step is carried out by supplying gasified magnesium into a mold in which a cast-in insert formed from an aluminum alloy, or an aluminum-based composite material is set,
6986379 Method and apparatus for casting aluminum by casting mold January 17, 2006
An aluminum casting process using a casting mold in which after the cavity (25) is filled with an inert gas, magnesium is introduced in to the cavity to have a magnesium layer (58a) deposited on the cavity wall. Then, nitrogen gas is introduced into the cavity to form magnesium nitri
6981303 Blank feeding method January 3, 2006
A method of feeding a blank (31) by cutting a billet (11) for plastic working includes the steps of superimposing a plurality of annular members (15 to 18) having a coefficient of linear expansion smaller than that of the billet and an inside diameter slightly greater than the outsid
6923242 Aluminum casting method August 2, 2005
An aluminum casting method includes the step of applying in advance a mold release agent including magnesium to a mold surface. Thereafter, a nitrogen gas is injected into a cavity to cause reaction between the magnesium in the surface of the mold release agent and the nitrogen gas,
6880681 Brake drum and method for producing the same April 19, 2005
A brake drum includes a ring-shaped drum body (13), and a friction member (16) secured to the inner circumferential surface (18) of the drum body. Because the drum body is formed of a lightweight Al alloy and the friction member is formed of an Al-base composite material, the brake drum
6871691 Apparatus for injection molding metallic materials March 29, 2005
A method for injection molding a metallic material is disclosed in which an injecting material comprised of a half-solidified metallic material and a molten metallic material is injected into a cavity of a die from an injection cylinder through a gate thereof. A non-product portion remai
6609286 Process for manufacturing a part of a metal matrix composite material August 26, 2003
A part is manufactured from a composite material containing an aluminum alloy as a metal matrix. Blanks are prepared from a billet of the composite material, and worked on in a press, while they are held at a temperature ranging from the solidus temperature, Ta, of the aluminum alloy
6505670 Method for injection molding metallic materials January 14, 2003
A method for injection molding a metallic material is disclosed in which an injecting material comprised of a half-solidified metallic material and a molten metallic material is injected into a cavity of a die from an injection cylinder through a gate thereof. A non-product portion remai
6303236 Method for manufacturing aluminum-based composite plate and composite back plate October 16, 2001
A method for manufacturing an aluminum-based composite plate is disclosed. The method comprises the step of producing an aluminum-based composite billet. The billet production step includes reducing, by magnesium nitride, an oxide-based ceramic as a porous molded body. The reduced ox
