Mouldtech Industries offers Spheroidal Graphite Ductile Iron Casting. Mouldtech Industries is an ISO 9001-2000 registered company. Spheroidal Graphite Ductile Iron Casting is unique combination of carbon and silicon with very low percentage [Trace] sulphur in nodular shape than flake after metal treated with magnesium alloys. Spheroidal Graphite Ductile Iron Casting has successfully replaced steel forging and malleable iron casting with proven techno commercial advantages. The discontinuities which graphite flake creates in grey in grey iron are eliminated in nodular iron and the result and material has greatly improved properties including a high degree of toughness. Moreover, there is no limit to the size and nature of the casting.
