We're looking for a robust 4-column hydraulic press designed to maintain structural integrity under high pressure. Key specs include nominal pressure of 1,500 kN, compacting pressure between 60-80 MPa, and an ejection force of 300 kN. The system should utilize an AC servo-hydraulic pump with a stroke of 400-500 mm and a max open height of 700-800 mm. Crucially, the press must support advanced features such as multi-stage compaction profiles and a micro-de-airing pause to enhance product quality. Tooling should use tungsten carbide liners, and the design needs to ensure precise ejection without damage. Lastly, we're interested in automated charging solutions and a vacuum de-airing system to optimize throughput and ensure product integrity. Performance guarantees on cycle rates and die lifespan are essential.
