01 — Press System

315 Ton Four Pillar Hydraulic Press Machine

A mid-range heavy-duty 315-ton four-pillar hydraulic press configured specifically for the medical powder metallurgy compaction of structural orthopedic implants. It incorporates high-rigidity guidance and micro-meter level ram control to deliver uniform compaction along elongated mold cavities.

Use Case

Designed for the cold compaction of medical-grade biocompatible metal powders blended with clean organic additives into high-integrity green preforms. It produces elongated orthopedic plates, structural rods, and trauma fixation components ready for sintering.

  • Core Applications: Essential for manufacturing load-bearing trauma plates, intramedullary rods, spinal reconstruction hardware, and structural orthopedic fixation devices. Widely deployed across medical device manufacturing, orthopedic trauma engineering, and surgical implant production lines.
  • Material: Processes high-purity medical-grade powders including Ti-6Al-4V titanium alloys, cobalt-chromium, stainless steel (316LVM), and specialized biocompatible alloys. Blended with clean-burning organic binders, lubricants, and compaction aids to achieve precise density distribution and residue-free sintering.
  • Products Processed: Produces straight and contoured bone plates, spinal stabilization rods, pediatric trauma pins, dynamic hip screws, and reconstructive bone brackets. Delivers near-net-shape green preforms with excellent edge retention and uniform density along long axes.
  • Why 315-Ton Hydraulic Press: Provides the optimal pressing force required to compact long, thin geometries uniformly without density gradients or bow warping. Ensures rigid deflection resistance across wider platen areas to maintain exact dimensional tolerances for critical surgical hardware.
