OverviewLearn how Bosch Rexroth and Keymark’s major overhaul of a half-century-old aluminum extrusion press gave it new life.
Keymark’s 8-inch aluminum extrusion press, in constant operation for more than half a century, had over time become increasingly undependable, breaking down frequently and requiring expensive repairs. In 2023, the press was upgraded extensively, with its deteriorating original parts swapped out for state-of-the-art components, including a hydraulic power unit, electrical controls, prefill valves, transducers, and piping.
These changes transformed the aging press, dramatically improving its energy efficiency while giving it newly fine-tuned controls and an intuitive troubleshooting system.
