Molten Metal Flow in Die-casting of Circular Disc

FLOW BEHAVIOR OF MOLTEN METAL IN ALUMINUM LFC PROCESS

The effects of gating system and pattern geometry on the metal flow in the lost foam casting (LFC) process have been investigated using glass covered mold and video recording system. Unlike convectional casting process, the type of the gating system showed little effect on fillability in lost foam, but pattern thickness had large effect on mold filling. The mold filling behavior seems to be con...

Optimalization of Die Shap and Flow Lines in Non-Linear Dies in Extrusion of Non-Circular Sections

In this paper, an analytical method for noncircular shape extrusion is presented. Using this method, non-linear deformation field can be described with Hermit cubic spline which is prescribed by the boundary conditions of the die at its entryand exit. The upper bound method has been used to obtain optimum coefficient of the tangential boundary conditions. The results show that the optimum tange...

Collaborative Research: Manipulating the Contact and Solidification of Molten Metal in Continuous Casting

A technology to enable continuous casting of molten metals, in a single step, to the specifications of the designer is being developed[7]. For example, casting aluminum foil in a single step could reduce CO 2 emissions to the atmosphere by 250,000 tons per year, in the US alone. Furthermore every kilogram of aluminum saved by reducing manufacturing waste translates into electricity saved at the...
