Check the molten iron chemistry and real-time temperature, before pouring. Since molten iron is qualified, we do fast pouring within 8 minutes.
Regarding ductile iron, to keep stable of nodulizing, we use wire-feeding equipment. The equipment not only lower air pollution, but also increase casting quality.
We make test specimens that got from end of pouring melting material. Check melting material chemistry, mechanical property and metallograph phase. Specimens and test results are stored for three years.
