to determine the prices of iron castings
overseas buyers may wonder how to
determine the prices of
As a marketing manager in
Foundry for many years, herein, I just
list some main aspects to help the
buyers to understand this issue.
The following aspects will help the
manufacturers to determine the prices of
1. The materials of cast iron
of cast iron is very important factor.
When we see the material grade, we will
know if we can make this products and
the cost for the materials. Higher
grades will cost more than lower grade,
and adding alloy will cost more than no
alloy. If your materials include some
content of Cr, Ni, Mo, Cu elements, then
cast iron prices will be much more higher than
2. The complexity of rough casting
The complexity means the size and
structure. Too large or too small
castings will cause more costs than
normal size castings. The castings with
complex structure will cause more
defective rate and need more sand cores,
so will need more costs.
3. The dimensional tolerance for
dimensional tolerance of rough
casting means none machined dimensions.
The stricter tolerance will mean the
higher casting process, such as
sand casting process,
hot shell molding,
lost wax investment
casting etc. Higher casting processes
will cause the large differences of
4. The requirements of machining
Machining requirements will affect the
machining prices, which include the
machining dimensional tolerance,
smoothness and machining work
If the castings are very large, need
high precision machining, or need to
machine many positions, then the
machining cost will be higher.
5. Surface coating requirements
Surface coating includes the primer
painting, finish painting, anti-rust
electric zinc galvanize, hot dip
chromium plating etc.
Different coating will cause different
In addition, there are many other
factors need to be considered, such as
heat treatment requirements, dynamic
balance requirements, inside flawless,
rough surface quality,
pressure testing, surface flaw
requirements and packing requirements.
The manufacturers need to consider all
of these factors, then determine the
prices of iron castings.
