The local microstructure and physical properties of an injection moulded PA66 was observed by using combined characterizations. The influence of the manufacturing process on the local structure and mechanical behaviour of the material was analyzed. Interrelations exist but are complex even if it was found that all mechanical properties significantly depend on the location into the material.
