CAST IRON PRICE PER POUND
For some iron casting products, the cast
iron price per pound is very useful for buyers to evaluate the price
level of suppliers.
The price per pound is related to many factors, such as the iron
materials, casting unit weight and size, design complexity,
casting production processes,
painting requirements, machining work load and annual demand. Let us
to elaborate these factors and the prices accordingly, please notice
that the following price USD/lb is only the costs ex-factory, which
will exclude painting, packing and inland transportation costs in
China. As for the updated cast iron per kg, please check our website
www.iron-foundry.com.
If you want to calculate accurate iron
casting costs, including rough casting, machining, painting and
packing, please use our better price calculation tool "Cast
Iron Price Calculator", which is free of charge.
If you want to learn about rough cast
iron price per kg or per ton, please refer to our "Cast
Iron Prices Per lb, kg, ton".
The following price sheet is just a
rough estimation of cast iron cost.

Green Sand Molding
- this production process is very common. It is suitable to produce
iron castings with unit weight from 1 lb to 700 lb. The structure is
comparatively simple, and low requirements to the surface quality
and casting defects.
Resin Sand Molding -
this casting process is more expensive because of using furan resin
materials. It is suitable to produce iron castings with unit weight
from 200 lb to 5000 lb. The structure could be more complex and has
good surface quality, and less casting defects.
Shell Sand Molding - this
casting process is even more expensive than resin sand casting
process. It is suitable to produce iron castings with weight from 1
lb to 100 lb. It could produce castings with very complex
structures, and high dimensional tolerance and surface quality.
In addition, the following factors will also affect the cast iron
price per pound:
1. Unit Weight - if the weight
per piece is too small (less than 1 lb), then the price per pound
will be extremely high, because it will cause more extra materials
and cleaning works.
2. Complexity of Casting - if the
inside of outside structure is very complex, it will mean more sand
boxes and sand cores, so it will cause the prices higher than
normal.
3. Material Grades - as for the
low and middle grades of cast iron, such as GG15, GG20, GG25, GGG40,
GGG50, the casting prices made by them will be very close, but as
for high grades, such as GG30, GG35, GGG60, GGG70, GGG80, their
prices will be higher since they will require heat treatment and
higher technical requirements.
4. Machining Costs - if the
machining requirements or work load is higher, then the machining
cost will be higher than that listed in the above table. Of course,
if the machining works are very small, then the machining price will
be very low comparatively.
5. Painting Requirement - the
normal flat primer paint is the most cheap one, and gloss primer
paint will be more expensive, and the gloss finish paint will be
more costly. Of course, if you require zinc galvanizing,
electrophoretic paint, or other surface coating, then the price will
be much more higher than normal.
6. Annual Demand - this is also
an important factor to price. The large annual demand such as larger
than 100 tons per year will get a good price for buyers, but if the
annual demand is very small, then the prices will be comparatively
higher than normal.
The following castings were produced by Dandong Foundry in China,
and their prices were settled by USD per pound.
Cast iron counter weight for machinery, produced by
green sand casting process.
Iron blocks for elevators, produced by furan resin sand.
Crane ball castings, produced by resin sand casting
process.
