Abstract:
Sand casting, also known as sand molded casting, is a metal casting process
characterized by using sand as the mold material. The term "sand casting" can
also refer to an object produced via the casting process. Over 70% of all metal
castings are produced via this process. Mold Compactors are essentially
“Vibrating Tables” of a much more rugged design. The “pattern” which shapes
the casting is already inserted in the Mold. Sometimes it is made of wax so it
will melt and evaporate when the hot molten metal is poured into it. The need
for compaction is to ensure the Mold sand fills every nook and crook around
the surfaces of the installed pattern. In this research, the student made
research on preparing the Mold for sand casting using vibrating table and
identify the suitable sand composition for sand casting using vibrating table.
The prepared Mold is set down on the top of the vibratory machine with
different amplitude. The entire Mold is then vibrated as necessary for it to
achieve the wanted degree of densification.
