Together with the Technical Service of SMS group, Erbslöh Aluminium Gmbh in Velbert, Germany, has implemented a complete modernization of its 20-MN extrusion press. The objective of the modernization was increasing productivity, expanding its product portfolio, safeguarding plant availability and improving energy efficiency. At the same time, the extrusion force was boosted to 22 MN.
For increasing productivity and expanding the product portfolio the press window has been enlarged. A movable shear for discards patented by SMS group, a new linear billet loader and a complete new hydraulic system were installed. Besides safeguarding spare parts availability, productivity could be enhanced with the new hydraulic system thanks to reduced non-productive times. Another development of SMS group, the ecoDraulic system, made it possible that a significant increase of energetic efficiency was achieved. With its intelligent automatic start-stop function, this system deactivates the hydraulic pumps not used in the extrusion process.
In this connection, the complete electrical equipment was installed and the latest visualization technology was employed which at the same time laid the foundation for an entry into digitalization.
