Hydraulic systems are the backbone of aluminum extrusion presses, providing the force and control necessary for shaping aluminum into various profiles[7]. However, these systems are complex and prone to failures that can lead to downtime, reduced productivity, and costly repairs[7]. Understanding how to diagnose and repair these failures is crucial for maintaining efficient operations. This article provides a detailed guide to identifying common hydraulic issues in aluminum extruders and implementing effective solutions, and emphasizes the importance of regular maintenance[1][7].
