ABSTRACT --- The ever increasing demands for higher productivity and recovery at
the extrusion press focus attention on the mechanical, thermal, and electrical design of
the container, this increasingly complex but essential part of extrusion press tooling.
Research and development into the design and operating conditions of the modern
thermally controlled container started by revisiting the traditional approach to container
design and, in doing so, revealed many modern misconceptions as to the cause of
container failures, whether they be catastrophic cracking, softening of the mantle,
or slipping liners. Employing the finite element method to extend the research has
enabled an understanding of the optimum placement and control of heaters, cooling
passages, and thermocouples. The paper discusses a package of features that are
becoming essential to manage the aluminum extrusion process.
