casting process as it is related to many internal defects (sand blow holes pinholes scabs metal penetration mold shift mold crack sand drop.). The target of the green sand casting process is to achieve "lower casting defects" while minimizing the effect of uncontrollable parameters. 3. Make the green sand casting process under the

PDF Optimization of Casting Process Parameters through

Casting simulation helps visualize mold filling and casting solidification predict related defects like cold shut shrinkage porosity and hard spots and optimize the casting design to achieve the desired quality with high yield. Flow and solidification of molten metals is however a very complex phenomenon that is difficult to simulate correctly by conventional computational techniques

An introduction to ceramic forming processes

The slip casting process Slip casting is the process of filling a porous mould (1) usually a gypsum mold with a ceramic slurry (3). The water is removed from the slurry via capillary action through the small pores in the mold (4). As the water is removed the ceramic particles are collected against the surface of
