![]() ![]() ![]() However, best results can be achieved by concurrent engineering approach wherein the foundry and tooling engineers actively participate in the product design phase and simultaneously evolve the product, tooling and process design thereby ensuring mutual compatibility. ![]() This method requires expert handling of the inputs which are normally not easily accessible to the product designers. The results from these studies are applied in predicting casting defects like hard spots, blow holes, cold shuts, shrinkage porosity, cracks and distortion. It also takes in account models of product and tool equipment like cores, parting, mould layout, feeders, gates etc., along with temperature regulated properties of mould and part materials and finally the process parameters such as pouring rate, temperature etc. Typically the simulation process comprises of processes such as mould filling, grain structure, stress analysis, distortion and solidification. Casting simulation technique has been proven to be very effective and reliable for a wide category of cast metals and complex processes, but its inaccessibility and high costs makes it practical application very difficult. Casting simulation is a very critical aspect of the casting process which ensures perfect casting in the shortest time span.
