Learn about Green Sand, Green Sand Filter and Green Sand
Molding.
Sand
casting is the most ancient form of metal casting and has been around since at
least Ancient Egypt. Many metal casters prefer using sand casting over many of
the other forms of processes because it’s cheap and the sand used is readily
available.
Many experienced metal casters will continue to use sand casting even though
their abilities and resources allow them to use the other metal casting methods
like Lost Wax Casting or Investment Casting. Sand casting involves less
material and less effort than the other casting methods. Sand casting is a
great way for new casters to get into the trade.

Learn about the basics of Iron Casting, types of
IronCasting, and the process of Iron Casting.
Iron castings can be referred to as products made out of
melted iron molecules. These molecules are, first, poured into mold and allowed
to cool. They are then extracted. The casting properties depend a great deal on
the foundry practice. They also depend on the cooling rate. Iron contains huge
carbon concentrations. This content facilitates melting, simplicity of casting,
and machining. Iron casting designs have a great variation owing to the
property of iron to resist shrinkage during the process of cooling. The end
product attains a great reputation for its strength and durability. Tensile
strength ranges between 20,000 psi and over 60,000 psi. The values of hardness
(without heat treatment) range between 100 and 300 BHN.
