01 — Press System

1250T Four Column Hydraulic Press Machine

The 1250-ton four-column hydraulic press delivers ultra-high force compaction with closed-loop proportional hydraulic control for heavy-duty powder metallurgy components. Its heavy-duty four-column guidance system maintains minimal deflection under high load, ensuring exceptional parallelism and dimensional stability.

Use Case

This system is designed for large-scale powder compaction of heavy-duty industrial gears, sprockets, and high-load structural parts. It generates high green density across large projected surface areas, minimizing structural porosity prior to high-temperature sintering.

  • Core Applications: Engineered for heavy industrial machinery, construction equipment, mining gearboxes, and heavy commercial vehicles. It manufactures high-torque transmission components that demand high load capacity and high fatigue strength.
  • Material: Processes iron-based, alloy steel (Fe-Cu-C, Fe-Ni, Fe-Mo), and stainless steel powders blended with graphite, binders, and solid lubricants. Copper and bronze powders are also processed for specialized heavy-duty wear plates and bush components.
  • Products Processed: Compacts large industrial spur gears, heavy-duty helical gears, drive sprockets, planetary gear carriers, and high-torque flange hubs. It handles complex multi-step geometries with thick cross-sections requiring high press force.
  • Why 1250-Ton Hydraulic Press: Delivers the extreme compaction force required to achieve high green density over large cross-sectional surface areas where smaller presses lack tonnage. The precise hydraulic control manages long stroke lengths and smooth multi-stage ejection without causing crack formation in large compacts.
