Castings Technology International. 67th World Foundry Congress
Magnesium is the lightest of the structural metals. Sand cast and HPDC
Magnesium is used in a wide range of markets and applications, from
automotive to aerospace. In all cases, weight saving is the primary reason
for using Magnesium alloys.
Precision cast Magnesium is not in widespread use. Main reason for this
lies in the potential reaction of molten Magnesium with Silica found in most
shell moulds. Recent work has shown that by modifi...

3D-Numerical simulations of squeeze moulding with the finite element method
Jürgen Bast / Abdulkader Kadauw
Technical University Bergakademie Freiberg, Germany.66th World Foundry Congress
Clay-bonded mould sand is widely used in the foundry industry due to its
environmental and financial advantages. Sand compaction plays an important role
for the quality of the mould and therefore for the quality of the casting. The
determination of optimal compaction parameters is often carried out by trial-and-
error-method, which is expensive and time consuming. To improve this situation,
the process of compaction is modelled here by se...
