The following data chart is showing the gray cast iron and ductile iron casting price rate history and price trend from 2008 to 2018. All data is from Dandong Foundry in China. Please treasure our hard works.
All these price rate is USD/kg, basing on the simple or normal complex castings, made by green sand of floor molding (currently by molding machine), so these prices should be the lowest prices. If the casting parts are very complex or need other casting processes, such as shell molding or resin sand molding processes, then its price should be about 20% higher than the following prices as our experience.
These price trend chart is only for your reference, could give you an idea how the cast iron price has changed in the past, so to estimate how they may change in 2019. As our experience, because of the higher material prices, manpower costs and pollution control in China, the iron casting prices should be higher in 2019.
