Yasuda Metal Industries, based in Osaka, Japan, has placed an order with SMS Meer for an extrusion press of type HybrEx 14. Yasuda intends to use the press, which can attain a maximum force of 14.5MN, to produce light-metal sections for windows and facades. It is capable of processing billets of up to 800mm in length and has a capacity of around 5,000 tons per year. Thanks to the drive technology used in the HybrEx 14, energy savings of up to 55% can be achieved compared to conventional presses.
The HybrEx press developed by SMS Meer uses its hydraulic system solely to generate the forming forces required for manufacturing semi-finished long products, with only the auxiliary movements of the extrusion press produced by dynamic, electric servo drives. Compared to the drives used in conventional presses, these drive systems can reach twice the speed, i.e., 1,000mm per second. A reduced non-productive time of just 1s means production can be increased by up to 100 tons per year. Key factors include the new press cylinder with integrated prefill chamber as well as the airtight tank with degassing unit. The press is equipped with the new OxiStop technology. The press is to be brought into service in the third quarter of 2016.
