A Design Study in Aluminum Castings - GM Cylinder Block                                          

Metal Pouring 
The cylinder block and head castings are produced at dedicated GM  casting facilities in Saginaw, Michigan and Defiance, OH. 

  • Three melt systems support casting production in five casting cells.  Each melt system contains a receiving furnace, a holding furnace, and a ladling furnace.

  • Metal is poured in each cell by a robotic pouring system.

These precision production facilities ensure that molten motel is poured at the correct temperature and the correct pour rate.

 24,000 lb Electric Ladling furnace in Saginaw

The aluminum is poured into the lost foam mold at a temperature 
of  ~ 1015C / 1500F.
