Disintegrative Core For Use In Die Casting Of Metallic Components
US Patent:
7013948, Mar 21, 2006
Filed:
Dec 1, 2004
Appl. No.:
11/000724
Inventors:
David E. Grebe - Fond du Lac WI, US
Mark P. Potratz - Fond du Lac WI, US
Mark P. Potratz - Fond du Lac WI, US
Assignee:
Brunswick Corporation - Lake Forest IL
International Classification:
B22C 9/10
US Classification:
164137, 164302, 164340, 164365, 164369
Abstract:
A disintegrative member, such as a salt core, is provided with a vent opening extending through its thickness from an outer surface to an inner surface in order to allow gases to pass radially inwardly through the body of the salt core and away from a region proximate the salt core's outer surface. The escape of these gases through the vent opening decreases the likelihood that porosity will be formed as a result of those gases being trapped in a region proximate the outer surface of the salt core because the molten metal solidifies more slowly in this area because of the thermal insulative qualities of the disintegrative member.
Die Casting Method For Semi-Solid Billets
US Patent:
8047258, Nov 1, 2011
Filed:
Jul 18, 2008
Appl. No.:
12/175871
Inventors:
Randall J. Zeimet - Oshkosh WI, US
Mark P. Potratz - Fond du Lac WI, US
Mark P. Potratz - Fond du Lac WI, US
Assignee:
Brunswick Corporation - Lake Forest IL
International Classification:
B22D 46/00
US Classification:
164 41, 164312
Abstract:
A die casting method for use with semi-solid metal billets allows the removal of air from portions of the billet as it is compressed and deformed to flow into a cavity of a die. The die is formed in a manner that captures other potential defects and impurities in portions of the finished die cast product that can easily be removed subsequent to the completion of the die casting operation. The air is removed through passages formed in a generally cylindrical rod that extends through a second surface of the die to allow the air to flow from pockets formed by a concavity of the billet and through the air conduit to the atmosphere.
Composite Core For Casting Metallic Objects
US Patent:
6478073, Nov 12, 2002
Filed:
Apr 12, 2001
Appl. No.:
09/833772
Inventors:
David E. Grebe - Fond du Lac WI

Assignee:
Brunswick Corporation - Lake Forest
International Classification:
B22C 910
US Classification:
164 28, 164132, 164369
Abstract:
A composite core structure is used for metal casting in order to form cavities of preselected sizes and shapes within the casting. The composite core has an insoluble support member that can be metallic and a soluble portion disposed around at least a part of the support member. When the composite core is used in a casting process, such as a die casting process, the soluble portion is dissolved after the casting process is complete, and the insoluble portion is then removed from the cavity that was formed through the use of the composite core.
