This User Guide will teach you how
to use our cast steel casting price calculator. Then, you could get
the casting and machining prices instantly by yourself.
1. Material Grade
Most of alloy cast steel will have the alloy Chrome (Cr), Molybdenum
(Mo), Nickel (Ni) and Copper (Cu). These alloy compositions will
affect their casting prices directly, so you must input their
composition (percentage) into our calculator.
You could search Google to get the chemical composition for your
alloy, for example, as for stainless steel 316, you could see its
chemical composition is Ni 10.00-14.00, Cr 16.00-18.00, Mo
2.00-3.00. So, you could input our calculator by Ni as 14.00, Cr as
18.00, Mo 3.00.
As for the carbon steel, such as mild steel, medium-carbon steel and
high-carbon steel, they do not have certain alloy composition, so
you do not need to input any alloy composition, just leave this area
2. Casting Weight
If you want to get the unit price USD/pcs, then you have to input
the unit weight. You may get the unit weight from drawings, after
input the unit weight, you need to tell our calculator what unit
weight it is. You could choose "Raw casting weight" or "Finish
"Raw casting weight" means the weight for castings before machining,
or do not need any machining.
"Finish weight" means the weight for machined casting parts, or the
castings after machining process. So, if the castings need further
machining works, then the "Finish weight" will be lighter than "Raw
Normally, if you get the unit weight from casting drawing, then it
should be raw casting weight, but if you get the weight from
machining drawing, then it should be the "Finish weight".
If you are not sure about what unit weight you get, then, as our
Dandong Foundry's experience, most of them are "Finish weight".
Be careful, this choice will affect the unit weight about 10% or
20%, so you must choose it carefully.
Why this price calculator can not be used for the castings with unit weight less than 1.0kg?
If the casting unit weight is less than 1.0kg, such as 0.9kg, 0.8kg etc., its raw casting price and machining price will be much higher than the result by this calculator.
If the casting weight is very small, its raw material prices will take small proportion to its price, but the manpower cost will take very high proportion. For example, if its unit weight is 5kg, then one worker can use 10 minutes to grind it, however, if it is only 0.5kg, then one worker may use 5 minutes to grind it, but 10 pcs (total weight 5kg) will use his 50 minutes. In other words, one worker will use 50 minutes to grind total 5kg castings. This is why the smaller castings will need higher manpower costs.
This is only one example. Actually the smaller castings will use higher costs from molding process to machining process.
Therefore, it is difficult to calculate the prices for small castings less than 1.0kg, the machining price must be calculated by the machining process, so have to check the machining drawings.
3. Complexity of Castings
The complexity of the castings will affect their prices. The complex
castings will need more materials to make sand cores, and also more
works for sand cores making and assembly. Also will cause higher
defective rates. All these will affect their prices.
Please choose one as your judgment to the complexity of your casting
"Very Simple" means your casting parts are very simple. Simple
shape, no complex inside structures, such as simple plate, rings,
balls. Most of counter weights could be taken as very simple.
"Normal" means the casting parts only have one hole or simple inside
"Complex" means the casting parts have complex inside or outside
designs, many characters. Not very easy to make.
"Very Complexity" means the casting parts are very complex, choose
this carefully, because it will affect the casting prices seriously.
If you are not sure about its complexity, you are better to choose
"Normal" or "Complex".
4. Selection of Casting Process
As for the steel castings, there are several different casting
processes, or called as casting production methods. The casting
processes will affect the casting prices very seriously, choosing
the suitable casting process will be very important.
If you do not have high requirements to the surface quality and
dimensional tolerance, then you could choose the sand casting
process, which is the cheapest one. Plus, if your casting part is
over 100 kg per piece, then you will have to choose the sand casting
If you have certain requirements to the surface quality and
dimensional tolerance, you could choose the lost wax investment
casting process by water glass material. This casting process is
much better than sand casting process, but its price is not low and
it can not be used to produce steel castings over 100 kg normally.
If you have very high requirements to the surface quality and very
high dimensional tolerance, then you could choose the lost wax
investment casting process by silica sol material. This casting
process could produce perfect steel castings, however, it can not be
used to produce large castings over 50 kg, and its prices are
extremely high. Do not choose it as long as you are sure you need
For the difference of these casting processes, you could refer to

Water Glass Investment Casting vs. Silica Sol Precision Casting
5. Machining Description
Dandong Foundry's casting price calculator could help you to get the
machining costs. Of course, the accurate machining cost is very
difficult to get unless you are very professional machining
engineer, so our calculator is just help you to get the approximate
If you just need raw castings, or the castings do not need further
machining, then you should choose "No Machining".
You could check how many positions or surfaces will need machining,
if there are many machining positions and surfaces, then you could
take it as complex or very complex.
If your casting parts need CNC centers, or very high accurate
machining, then you may choose complex or very complex.
If you think there are not many machining positions, or the
tolerance is not very high, then you could choose the "Normal
But please notice that the different machining complexity will
affect the machining costs very seriously, so please choose it
6. Surface Painting and Coating
If you want foundry to paint them or do some certain surface
coatings, then you could choose the painting method accordingly.
7. Packing and Delivery to Local Seaport
Packing cost means our Dandong Foundry will pack them into
fumigation-free plywood crates. We will also deliver them to our
local Dalian port, then they will be ready for shipment. This is FOB
If you want us to pack them and deliver them to the local seaport,
then you could choose the options accordingly.
Now, please click the button "Price Calculation", then you
will see the prices for the casting price, machining price, paint &
coating price, packing & delivery cost, and total price.
By the way, the Price Index FG, and RG are only used by us to adjust
the prices according to the current material and manpower costs. The
exchange rate will be adjusted by us too. So, the users do not need
to care about these data.
Please feel free to contact us if you have any question. We will be
glad to help you to use our calculator.
