A Case for Low Pressure Sand Casting of Aluminum

Solidification times are typically five times longer in sand casting than in permanent mold. This is why low pressure sand molding is no comparison to LPPM when castings are small enough to be produced on a LPPM press. Since the majority of aluminum castings are relatively small, the LPPM process is...

Description
Summary:Solidification times are typically five times longer in sand casting than in permanent mold. This is why low pressure sand molding is no comparison to LPPM when castings are small enough to be produced on a LPPM press. Since the majority of aluminum castings are relatively small, the LPPM process is much more widely used than low pressure sand casting. But when the dimensions are too large for LPPM, low pressure sand casting is a viable option.
