INTRODUCTION
1.1 CASTING WITH MOLD SAND The metal casting process is quite old, having its origins in the smelting of iron and copper already used in 3000 BC and developed significantly from the year 1340 with the invention of the oven streaming. To enable the manufacture of pieces with different geometries has developed a casting mold, wherein the mold with the shape of the part to be manufactured is filled with molten metal. The foundry sand mold allows the manufacture of parts with very complex geometries, but is an initial method of manufacture, and is usually followed by machining and heat treatments to achieve the desired result. The weaknesses of manufacturing by using foundry sand mold include high tolerances and embrittlement part due to the changes incurred in the grain structure of the metal by heating and phase change. The sand mold casting is used extensively in the steel industry for the manufacture of billets and rods. It is from them that all other geometries are manufactured marketed, such as pipes and plates. In automotive casting is of vital importance because it is the method currently used in the manufacture 100% of the blocks of combustion engines, these are aluminum or cast iron. Figure 1 shows a block motor Ford Mustang V6 3.7 L made of cast aluminum.
