Mould design and process simulation
Neue Materialien Fürth GmbH uses computer-aided geometry and process design methods for casting light metal components. Magnesium injection moulding, die casting of aluminium/magnesium and the associated mould design are amongst the primary applications of these methods. The aim of simulating the casting process is to devise the optimal design of part or casting system quickly and to identify and use the most appropriate process parameters.
MOULD DESIGN AND PROCESS SIMULATION:
HOW IT IS DONE
Computations are performed to simulate how the mould is filled and how the component solidifies. The mould filling is based on a cycle calculation that simulates the inhomogeneous thermal state of the mould. To assess the process design that has currently been selected, our experts ascertain the likelihood of casting defects occurring. When doing so, NMF GmbH considers defects that occur when the mould is filled like e.g. entrapped air, as well as shrinkage cavities and pores that form as the material solidifies.
If simulations are to be used to optimise the production of components, it is incredibly important to obtain high-quality results. The adjacent images of a die cast component being poured into a mould illustrate that reliable results are completely achievable. The computed mould filling is consistent with partial filling test results obtained by experimentation.
