HOW A PRESS CAN ENABLE THE DIE TO PERFORM AT ITS BEST:
THE COMETAL WAY
EXECUTIVE SUMMARY
3
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.
Key points•COMETAL OVERVIEW•INTRODUCTION TO COMETAL PRESS•Cometal has incorporated numerous solutions to allow the die perform optimally
– Statically determinate configuration – Shifting shear– Cylinders to hold the die stack in position– Full length pre-loaded structure
