01 — Press System

400 Ton Four Pillar Hydraulic Press Machine

This 400-Ton Four-Pillar Hydraulic Press is specifically engineered for high-precision compaction of soft magnetic composite powders into complex core geometries. It delivers highly controllable pressing forces with exceptional parallelism to safeguard delicate electrical and magnetic characteristics.

Use Case

Tailored for the efficient mass production of electromagnetic cores, this press forms high-density preforms used in automotive and industrial electronics. It integrates multi-stage pressure control and precise powder feeding to minimize core losses and maximize permeability.

  • Core Applications: Supplies critical electromagnetic components for electric vehicle motors, power inductors, transformers, and industrial actuators. It enables reliable high-frequency magnetic performance across modern energy and power conversion systems.
  • Material: Compacts soft magnetic composite (SMC) powders, pure iron powders, and alloyed ferromagnetic compositions. Integrated organic or inorganic insulating binders and lubricants preserve particle insulation and ensure high green density.
  • Products Processed: Produces stator and rotor segments, toroids, E-cores, pot cores, and custom-shaped magnetic inductors. These components achieve near-net shapes ready for low-temperature curing or sintering treatments.
  • Why 400-Ton Hydraulic Press: Achieving optimum magnetic permeability in SMC materials demands high, uniform density without crushing the particle insulation coating. The 400-ton capacity provides the exact pressure precision needed for medium-to-large magnetic core cross-sections.
