The type of iron foundries in China
As everyone knows, China has become the
largest metal casting manufacturing country, and have thousands of
various metal foundries. Herein, we try to classify the iron
foundries into five main types, and hope it could give an
approximate concept to the buyers who want to purchase metal
castings from China.
1. Large iron
foundries
Normally, these type of iron foundries are very professional, and
have several automatic molding lines, sophisticated inspection
devices, related high precision machining equipments, and hundreds
of workers. They could produce iron castings of dozens of thousands
of tons annually. Such as the
FAW Foundry.
However, these foundries usually supply
cast iron parts for the local or joint-venture automobile
manufacturers. So, they only accept super large orders, such as
hundreds of thousands of pieces annually.
2. Specific iron foundries
When I said specific, I meant they mainly produce one or several
types of casting parts, and normally do not accept the orders not
related with their main products. For example, some foundries mainly
produce ductile iron pipes, some mainly produced various standard
pipe fittings, some for stove parts, fishing castings, fire grates,
paper dryers, hydraulic parts etc.
These iron foundries are specialized with some type of castings, so
all their equipments and inspection devices are fitted with their
products, and their workers and engineers are familiar with those
products. So, they tried to be the best in their areas, and would
not like to insert some various products into their routine
production.
3. Medium-sized iron foundries
Medium-sized foundries means the foundries with over hundred
workers, one or two automatic molding lines, and about thousands of
tons output. These foundries usually have several types of molding
processes, such as automatic molding lines, resin sand casting
process, shell molding process and traditional green sand molding
process, some foundries use the molding machines.
These foundries have some normal machining equipments, so they could
do most of machining works in-house, and they have some basic
inspection devices to check the materials and dimensions.
Normally, these foundries do not have very special products. They
are willing to produce any types of iron castings that they could
produce. Such as machinery parts, pump and valve parts, pipe
fittings and many civil and industrial use castings. So, they could
accept middle and large orders, such as
Dandong Foundry.
4. Small iron foundries
Small foundries means the iron foundries who have dozens of workers,
and can produce hundreds of tons annually. Most of them use manual
green sand casting process and shell molding process, some small
foundries have some basic machining equipments, but they could just
make some rough and no n-precision machining works.
These foundries only have some basic
inspection devices, but they are willing to accept small orders, and
rough castings.
Most of small iron foundries in China could not export iron castings
directly, so they have to cooperate with the larger foundries or
trading companies.
