Thanks to special alloys and further heat treatments, iron casting can be used for example in the entire area of the automotive and mechanical engineering business. From heavy marine engine cases to connection rods for automobile engines, there is the adequate type of iron casting for every purpose. All iron casting qualities are classified and standardized according to DIN EN. This also includes the so called grey cast iron, which still turns out to be ideal for heavy machine tool bases as well as for pumps and engine cases. Other qualities can be used for high quality crankshafts or highly stressed machine components. This applies, for example, for the hand gear system of tailboards of modern passenger airplanes and for axle parts of vehicles. Another specialty of the KUNFENG casting is iron casting according to customer specifications in regard to individual characteristics.
