EXTRUSION MANDRELS
Extrusion mandrels are surrounded by the hot billet throughout the entire extrusion cycle. The thermal stress is correspondingly high. Piercing is also frequently carried out with the same mandrel. This results in high bending forces and compressive loads.
During the extrusion process, the material flows along the surface of the mandrel, which results in high friction and tensile loads. Extrusion mandrels are mainly used in the processing of heavy metals. The materials for mandrels for use with aluminium are also shown in the table. The quality of the mandrel determines the performance. S+C has extensive expertise in the manufacture of finished mandrels.
