AVA Tec. Group is one of the leading companies which established its closed relation with customers not just suppling material, for us providing solution for our customer is our mission.
Steel is the most versatile of the structural engineering materials, so more grades of steel are available for casting than any other type of alloy. The casting of steel presents a number special problems due mainly to the high casting temperature, typically 1550-1600°C, the volume shrinkage that occurs on solidification and the susceptibility of molten steel to oxide formation. Steel castings range in size from a few grams to hundreds of tonnes. Steel castings are often used in critical situations where optimum mechanical properties are essential so that freedom from casting defects is particularly important.
Iron foundries require metal of controlled composition and temperature, supplied at a rate sufficient to match the varying demands of the moulding line. The metallic charge to be melted consists usually of foundry returns, iron scrap, steel scrap and pig iron with alloying additions such as ferrosilicon. The majority of repetition iron castings are made in green sand moulds with resin-bonded cores. The great merits of grey iron are its low cost, its high fluidity at modest temperatures and the fact that it freezes with little volume change. Ductile iron has high ductility allowing castings to be used in critical applications.
The investment casting sector produces a broad range of high value added castings for the aerospace, power, medical and automotive industries amongst others, where quality demands are at their highest.
Foseco offers a growing range of products to help the investment casting sector address they key challenges it faces such as:
JODOVIT produces fluxes that prevent the formation of oxides and hard points.
Best results are obtained by using specific chimical auxiliares.
