Straight Side Press with 4 Guide Posts, 550 ton
DDH Series Mechanical Presses
This high-speed press is built with a central 4 guide post structure and an 8-way roller slide guiding system, providing exceptional load capacity, precision alignment, and long-term stability even under eccentric loads. Its extra-wide working table (4200×1300 mm), along with a shut height of 500-600 mm, stroke of 50 mm, pressing capacity of 5500 kN, and speed of 80-200 spm, makes it well-suited for complex, high-precision stamping applications.
- Extra-wide working table: The 4200 mm table accommodates large dies and supports complex stamping processes.
- Stable bottom dead center repeatability: Minimizes die wear and maintains product accuracy, ensuring consistent precision and longer die life.
- Minimized thermal displacement: Advanced thermal control technology, originally applied in smaller high-speed presses, effectively reduces heat distortion, improving precision during continuous operation.
- High-precision 8-way roller slide guiding system: The extended roller guide design provides excellent load-bearing capability, resists eccentric load deflection, and offers easy maintenance for long-term reliability.
