    1. 1. Guangdong Aluminum Processing (International) Seminar 2013-11-30 HOW A PRESS CAN ENABLE THE DIE TO PERFORM AT ITS BEST: THE COMETAL WAY 1
    2. 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. 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 Next steps •- visit FOSHAN COMETAL ! 3
    3. 3. COMPANY OVERVIEW Foshan Cometal Industrial Machinery Co,. Ltd (FCIM) An ITALIAN investment since 2004 FCIM has established itself at an international level as a leading company in the design and manufacturing of equipment for aluminum extrusion. 5
