(DIE) is the process of manufacturing of metal parts that is essentially filled with liquid metal to a mold cavity shaped and measures corresponding to the part to be manufactured / Melting point - is the temperature at which the metal passes from the solid to liquid / Flow - is the ability of a substance to sell more or less easily. For example, water is more fluid because the oil flows more easily / Foundry step-by-step: making the model, making the mold, making the males, melting, casting, mold, deburring and cleaning / Channel Power -- are the pathways, or conduits, through which the molten metal passes to get the mold / massalotes- Are reservoirs of molten metal that will offset the contraction of the metal part on the transfer of liquid to solid / Features: addition of an allowance, small holes and complex details are not made the play difficult because the casting process, radiussing and thickening of the walls of the workpiece defects: the inclusion of sand mold on the walls inside or outside part, defects in the composition of the alloy, causing the appearance of hard particles left in the material, sinks and porosity
(LAMINATION) Lamination is a process by which mechanical forming an ingot of metal is forced to pass between two cylinders that rotate in opposite directions at the same speed. /Hardening: This is the result of a change in the structure of the metal, associated with a permanent deformation of the grains of the material when it is subjected to cold forming. The hardening increases the hardness and tensile / facilities of a rolling ovens are made by heating and reheating of ingots, slabs and billets, roller systems to move products, lifting tables and tilting, scissors cut, and especially the mill /
