The conclusions of lost foam casting process

Was investigated various effects of process parameters such as the melting treatment, the packing material and the density model of the EPS foam on the porosity in lost foam casting of aluminum alloy. Found the highest density at the top of the bar, while that the density was lower...

The results and discussion of lost foam casting process

3.1 Change in density samples reduced pressure. The change in density and cross section of samples regardless reduced time pressure the degassed melt. Density increases gradually after degassing, and reaches a relatively stable level with time. It can be seen that small pores are scattered and not the upper...
