US Patent:

8061404, Nov 22, 2011

Filed:

Dec 18, 2009

Appl. No.:

12/623417

Inventors:

Robert W. Neal - Buffalo Grove IL, US
Michael A. Garin - Mahtomedi MN, US

Assignee:

MarcTech Innovative Design, Inc. - Buffalo Grove IL

International Classification:

B22D 19/04

US Classification:

164 98, 164109, 164333

Abstract:

A dual temperature mold assembly for maintaining a mold cavity used in a cast on strap process at two different temperatures facilitates the removal of the solidified strap after the molten metal is solidified. The mold assembly includes a mold cavity having walls attached to different mold assembly segments that are heated or cooled by thermal energy input and coolant processes which can maintain the mold cavities at different temperatures, so that molten metal around the battery plate lugs in a mold cavity segment is solidified while the sides of the mold cavity are exposed to at least one adjacent heated segment to provide thermal energy thereinto, resulting in a reduction of the amount of molten metal necessary for a cast on strap, and reducing the amount of thermal energy input into the process for manufacturing the straps.
