How to calculate the price of iron castings?
Learning about calculation and estimation
of iron casting costs
is important for buyers to make a right price evaluation. Herein, we
make a brief introduction to the process of casting price
calculation by manufacturers and suppliers.
When we receive the inquiries from clients, we will check the
1. Consider if we can produce the castings.
We need to check if the raw castings could be produced by
sand casting processes,
some could be made by green sand, some could be made by resin sand,
or shell molding, or automatic molding process. Green sand is
cheaper, shell molding is most expensive. The related aspects will
include the dimensional tolerance, surface quality, structure
complexity, annual demand, weight and size etc. All these factors
will affect the raw casting costs. Of course, if all these processes
could not meet the requirements, then we will not be able to produce
2. Consider if we can meet the machining requirements.
As for the normal machining works, most of
iron foundries with
machining capabilities will be able to do the machining in-house.
Otherwise, they will have to entrust other professional machining
workshops to do the machining, which is not the best choice, since
the cooperation between foundries and machining workshops may cause
more difficulties and delay of delivery.
Machining cost is difficult to quote since the price should consider
the machining equipments, work time, and price rate accordingly.
Moreover, the annual demand is also important issue, which affects
the machining costs.
3. Consider other costs.
Other costs will include the packing costs, surface treatments,
painting, inland and sea freights, and of course, the exchange rate.
These costs will be related with the specific requirements of
After our talking so much, you may still do not know how to
calculate the casting costs. Indeed, it is not a simple work to make
an accurate quotation, or price evaluation. There are many factors
that will affect the prices.
However, we still can make an approximate price range for
a) As for rough castings without machining works. You could refer to
our website iron-foundry.com, on it, you could see the various
casting price according to the different casting processes and
materials, such as grey iron
and ductile iron.
b) As for the machining costs, for the
simple machining or rough machining, the price is in the range 0.16
USD/kg to 0.80 USD/kg. For the complex or high precision machining,
the price is in the range 0.80 USD/kg to 1.60 USD/kg.
