Pouring the Molten Metal •For this step to be successful, metal must flow into all regions of the mold, most importantly the main cavity, before solidifying •Factors that determine success: Pouring temperature Pouring rate Turbulence ©2002 John Wiley & Sons, Inc. M. P. Groover, “Fundamentals of Modern Manufacturing 2/e”
Solidification of Metals Transformation of molten metal back into solid state •Solidification differs depending on whether the metal is a pure element or an alloy ©2002 John Wiley & Sons, Inc. M. P. Groover, “Fundamentals of Modern Manufacturing 2/e”
