Iron foundry is the metal foundry mainly
producing iron castings. There are
thousands of iron foundries in China.
Herein, I will talk about some main
aspects about the iron foundry in China.
Types of Iron Foundry
There are many types of iron foundries.
I just list some main types. One is
small iron foundry main using the green
sand floor molding process. Another is
the iron foundry using many different
casting processes, and normally these
foundries have machining capability,
such as our
Dandong Foundry. Third is the
iron foundry specifically producing
several types of iron castings, such as
papermaking dryer, pipe and pipe
fittings, certain automotive parts.
Main Equipments of
Iron foundry usually has cupola or
electric furnace as the main equipments
for melting the irons. Some large iron
foundries have the
automatic molding lines or
molding machines. As for small iron
foundries, they use hand molding method,
so there are no these machines. Some
foundries have shooters for making the
resin core and shell, please refer to
our another article
Molding for more about these
All iron foundries have sand cleaning
equipments such as various sand blasting
machines and grinding machines.
There are many iron foundries in China,
who have machining equipments, so they
could do the rough and finish machining
Main Products of Iron
Since the iron castings are the base of
living and industry, there are too many
types of iron castings. When you see
some iron parts, probably, they were
made by casting process. Herein, I list
some main types of foundry products.
Such as the iron parts for
agricultural and engineering trucks
and machineries, for automotive
vehicles, for civil facilities, for
and boilers, for
and valves, for ships and boats
and many fields.
Main Problem of Iron
There are many problems in iron
foundries. Firstly, iron foundries can
cause the pollution to environment.
Therefore, the iron foundries are few in
developed countries. Secondly, the
working condition is very bad, so the
salaries of workers are higher and
higher. Thirdly, the prices of iron
castings will be mainly affected by the
pig iron and iron ore, so the prices are
unstable in recent years. Fourthly, the
profit margin is very small because of
serious competition and low technology.
Fifthly, the workers and administrative
staff have low level of education,
therefore, it is difficult to reach a
good administration level.
However, iron foundry is still essential
for all industries, so they should have
better development in the future.
