How to: Aluminum Sand Casting Process & Manufacturing
Aluminum sand casting is a metal casting process where sand is used to mold material together. Currently, a majority of metal castings are produced by the sand casting process. This is largely because aluminum sand casting is a very cheap and effective means of molding material together.. Sometimes for increased durability, the sand will be mixed with clay.
The process is versatile and cost effective, even for low volume runs because of tooling cost. Nearly any part configuration that can be made using another casting process can be reduced to a pattern and created as a sand casting. The MetalTek Sand Casting Process:
