Squeeze casting - back extrusion technique

摘要

Modeling and simulation of the solidification process are very important in order to predict the parameters which affect the casting properties, which in turn reduces the practical trials prior to production. A modification to the squeeze casting process which a clear and is set between the plunger and die in order to avoid the Modeling and simulation of the solidification process are very important in order to predict the high resistance of the early formed solid skin. The amount of the chosen clearance is of great importance to the success of the process. This clearance allows a small portion of the cast melt to back extrudes. The proposed expression that had been verified experimentally on Al-Si alloy castings.
