Dependence of aluminum hollow section's quality on characteristics of hollow dies

Hollow aluminum sections are currently manufacture by means of extrusion through hollow dies. Connections between characterististics of hollow die, metal flow and hollow section's quality are shown by several characteristic examples. Analyses have shown that the type of hollow die and its design have impact influence on the quality of section's longitudinal joints. Results of investigations could be useful for industrial practice.
