Friction stir extrusion is an innovative direct-recycling technology for metal machining chips.During the process a specifically designed rotating tool is plunged into a cylindrical matrix containing the scraps to be recycled.The stirring action of the tool prompts solid bonding related phenomena allowing the back extrusion of a usc trojans snapback hat full dense rod.

This process results to be particularly relevant because allows the reuse of the scrap without any previous nitrile gloves in a bucket treatment.Experiments have been carried out in order to investigate the influence of the process parameters on the extrudes quality and a numerical model has been developed in order to simulate the evolution of the material flow.
