01 — Press System

630T Four Column Hydraulic Press Machine

The 630-ton four-column hydraulic press features heavy-duty structural rigidity and proportional hydraulic control for compacting large powder metallurgy components. Its balanced four-column guidance ensures uniform force distribution and precise alignment under heavy compaction loads.

Use Case

This system is engineered for high-density compaction of large-diameter bearings, thick-walled bushings, and heavy-duty structural sleeves. It delivers high pressing force over broad surface areas to produce strong green compacts suitable for oil impregnation and sintering.

  • Core Applications: Engineered for heavy commercial vehicles, off-highway machinery, industrial equipment, and renewable energy gear systems. It manufactures large-scale self-lubricating journal bearings, high-load suspension sleeves, and heavy wear rings.
  • Material: Processes iron-based, bronze (Cu-Sn), iron-copper alloys, and stainless steel powders blended with graphite, lubricants, and binding agents. These formulations ensure consistent green strength and optimal matrix porosity for subsequent oil impregnation.
  • Products Processed: Compacts large flanged journal bearings, thick-walled cylindrical bushings, heavy drive-shaft sleeves, guide bushes, and split-bearing liners. It produces complex multi-level geometries with strict concentricity and wall-thickness requirements.
  • Why 630-Ton Hydraulic Press: Delivers the high tonnage required to achieve uniform target green density across large cross-sectional pressing areas without overloading tooling. Its controlled pressing velocity and multi-stage hydraulic ejection prevent laminar cracks and density gradients in long or thick-walled parts.
