HOW A PRESS CAN ENABLE THE DIE TO
PERFORM AT ITS BEST:
THE COMETAL WAY
1
2. EXECUTIVE SUMMARY
Cometal has integrated in its extrusion press numerous solutions to
enable the die to perform at the best.
No matter the resources spent into the design and manufacturing, the
performances of the dies are heavily affected from the operating
conditions and therefore the extrusion press can play a very big role on
this.

The extrusion is an adding value process in which the performances of the die are critical both on productivity, qualitto allow the die to remain orthogonal to the extrusion liney and repeatability of the process.
