Patent number: 9302312Abstract: Sheet metal workpieces are preheated to a temperature in the range of about 100° C. to about 500° C. for warm forming between press-actuated forming dies. The forming dies are not heated, but are coated with a liquid lubricating material suitable for the forming of the preheated sheet metal workpiece. For example, the liquid lubricating material is suitably a halogenated hydrocarbon that will adhere to unheated die surfaces and serve in the forming of the sheet metal workpiece into a vehicle body panel or other product. But the liquid lubricating material is composed so as to evaporate from surfaces of the formed workpiece at a temperature below about 200° C., so that the workpiece does not have to be cleaned before it is decoratively finished. The lubricant material may be vaporized, for example, into a warm stream of air or nitrogen and carried to a recovery or disposal system.Type: GrantFiled: February 7, 2014Date of Patent: April 5, 2016Assignee: GM Global Technology Operations LLCInventors: Anil K. Sachdev, William R. Rodgers

Patent number: 8747606Abstract: A method of forming an adhesive bond between a first substrate and a second substrate includes applying a semi-crystalline polymeric adhesive composition to a bonding area of the first substrate, and, after applying, disposing the second substrate adjacent to and in contact with the composition to form a workpiece. After disposing, the method includes heating the workpiece to cure the composition and thereby form a crosslinked polymeric adhesive material. After heating, the method includes cooling the workpiece such that the material has a crystalline molecular structure. Concurrent to cooling, the method includes imposing a stress on the material to thereby orient the crystalline molecular structure in a desired direction, and, after imposing, dissipating the stress along the crystalline molecular structure in the desired direction to thereby form the adhesive bond between the first substrate and the second substrate.Type: GrantFiled: March 31, 2011Date of Patent: June 10, 2014Assignee: GM Global Technology Operations LLCInventors: Tao Xie, Hamid G.
