Abstract
Numerical simulation of the powder injection moulding of the stainless steel feedstock was performed using finite elements/finite differences method. Influence of the process parameters on the temperature development in the moulded part was estimated. Frictional heating between the layers of the feedstock with different viscosity may cause the temperature rise to a level dangerous for the integrity of the feedstock. Both process conditions and position of the gate affect the temperature distribution within the part. The temperature homogeneity can be improved by optimisation of the mould design and process conditions.
