sand casting technology, from material to pouring theory. Metal melting, metal casting, resin sand casting and green sand casting.
What is Green Sand Casting? Green Sand Casting is mainly differed with resin sand casting . The mould sand is taken from rivers, and then put some others in sand to increase their viscidity. Green sand is an aggregate of sand, bentonite clay, pulverized coal and water. Its principal use is in making molds for […]
A sand casting is also divided resin sand casting and green sand casting. sand casting is produced when molten metal is poured at atmospheric pressure into a cavity formed in a compacted molding sand. In typical ferrous casting, the mold would be bonded with 6 to 8 percent western bentonite mulled with 2 to 3 […]
The sand casting comprison in green sand casting, resin sand casting.Sodium silicate bonded sand casting and dry mould casting
Electric Arc Furnace is a furnace that heats charged material by means of an electric arc. Arc furnaces range in size from small units of approximately one ton capacity (used in foundries for producing cast iron products) up to about 400 ton units used for secondary steel making. Arc furnaces used in research laboratories and […]
Sand casting is used to make large parts (typically Iron, but also Bronze, Brass, Aluminum). Molten metal is poured into a mold cavity formed out of sand (natural or synthetic). The processes of sand casting are discussed in this section, include patterns, sprues and runners, design considerations, and casting allowance.
