400 Ton Four Pillar Hydraulic Press Machine Production Line

An advanced heavy-duty 400-ton four-pillar hydraulic press custom-engineered for medical-grade powder metallurgy compaction of large orthopedic joint components. It features maximum platen stability and multi-stage pressure controls to deliver exceptional dimensional repeatability across substantial press footprints.

Use Case

Designed for the cold compaction of high-purity medical metal powders blended with clean organic additives into large, high-density green preforms. It provides the substantial tonnage needed to shape large joint reconstructive implants prior to high-temperature sintering.

  • Core Applications: Essential for manufacturing load-bearing total joint replacement components, hip stems, knee femoral components, and large pelvic reconstructive hardware. Widely utilized across orthopedic implant manufacturing, specialized biomedical engineering facilities, and surgical reconstructive device production.
  • Material: Processes medical-grade metal powders including Ti-6Al-4V titanium, cobalt-chromium alloys, stainless steel (316LVM), and biocompatible powders. Formulated with clean-burning binders, organic lubricants, and compaction aids to promote uniform cavity filling and residue-free debinding.
  • Products Processed: Produces femoral hip stems, knee joint femoral components, tibial trays, acetabular cups, and large structural pelvic fixation plates. Generates net-shape green compacts with high surface integrity and precise volumetric geometry to minimize post-sinter machining.
  • Why 400-Ton Hydraulic Press: Delivers high, uniform compaction force across large cross-sectional areas to achieve the green density required for heavy load-bearing implants. Maintains rigid four-pillar guidance and deflection resistance to protect complex mold tooling and ensure micron-level dimensional precision.
