For some iron casting products, the cast iron price per pound is very useful for buyers to evaluate the price level of suppliers.

The price per pound is related to many factors, such as the iron materials, casting unit weight and size, design complexity, casting production processes, painting requirements, machining work load and annual demand. Let us to elaborate these factors and the prices accordingly, please notice that the following price USD/lb is only the costs ex-factory, which will exclude painting, packing and inland transportation costs in China. As for the updated cast iron per kg, please check our website www.iron-foundry.com.

If you want to calculate accurate iron casting costs, including rough casting, machining, painting and packing, please use our better price calculation tool "Cast Iron Price Calculator", which is free of charge.

If you want to learn about rough cast iron price per kg or per ton, please refer to our "Cast Iron Prices Per lb, kg, ton".

The following price sheet is just a rough estimation of cast iron cost.

Green Sand Molding - this production process is very common. It is suitable to produce iron castings with unit weight from 1 lb to 700 lb. The structure is comparatively simple, and low requirements to the surface quality and casting defects.

Resin Sand Molding - this casting process is more expensive because of using furan resin materials. It is suitable to produce iron castings with unit weight from 200 lb to 5000 lb. The structure could be more complex and has good surface quality, and less casting defects.

Shell Sand Molding - this casting process is even more expensive than resin sand casting process. It is suitable to produce iron castings with weight from 1 lb to 100 lb. It could produce castings with very complex structures, and high dimensional tolerance and surface quality.

In addition, the following factors will also affect the cast iron price per pound:

1. Unit Weight - if the weight per piece is too small (less than 1 lb), then the price per pound will be extremely high, because it will cause more extra materials and cleaning works.

2. Complexity of Casting - if the inside of outside structure is very complex, it will mean more sand boxes and sand cores, so it will cause the prices higher than normal.

3. Material Grades - as for the low and middle grades of cast iron, such as GG15, GG20, GG25, GGG40, GGG50, the casting prices made by them will be very close, but as for high grades, such as GG30, GG35, GGG60, GGG70, GGG80, their prices will be higher since they will require heat treatment and higher technical requirements.

4. Machining Costs - if the machining requirements or work load is higher, then the machining cost will be higher than that listed in the above table. Of course, if the machining works are very small, then the machining price will be very low comparatively.

5. Painting Requirement - the normal flat primer paint is the most cheap one, and gloss primer paint will be more expensive, and the gloss finish paint will be more costly. Of course, if you require zinc galvanizing, electrophoretic paint, or other surface coating, then the price will be much more higher than normal.

6. Annual Demand - this is also an important factor to price. The large annual demand such as larger than 100 tons per year will get a good price for buyers, but if the annual demand is very small, then the prices will be comparatively higher than normal.

The following castings were produced by Dandong Foundry in China, and their prices were settled by USD per pound.

Cast iron counter weight for machinery, produced by green sand casting process.

Iron blocks for elevators, produced by furan resin sand.

Crane ball castings, produced by resin sand casting process.
