Track: EXTRUSION EQUIPMENT - Safety and Automation

ABSTRACT—Modern hot aluminum extrusion plants are highly automated and optimized to
meet customer needs and to produce at low cost. Automation of a stretching line reduces the need
for human work in the stretching of extruded shapes. To be able to fully automate the stretching
line it is necessary to have a good understanding of the aluminum alloy stretching mechanism.
The impact of several process and material parameters on the automated profile stretching were
studied. The theory of material deformation during different stages of the stretching process was
also evaluated. Based on practical and theoretical work results, a set of guidelines for automated
profile stretching was established. A few case studies are presented where practical applications
of the results are demonstrated.
