- •
A granular model for the simulation of PIM was proposed.
- •
The model enables a direct prediction on the density distribution.
- •
Effects of moulding parameters are investigated.
- •
Verification works are carried out on two moulds with designed features.
- •
The experimental results show good agreement with the simulation.
