Vacuum Hot Pressing Sintering

Simultaneous pressure and high-temperature heating in vacuum for near-net-shape densification.

What This Process Solves

Simultaneous pressure and high-temperature heating in vacuum for near-net-shape densification.

Optimized design

Good temperature uniformity

Fast heating rate

High pressure accuracy

High safety performance

Suitable Materials & Applications

Ceramic / metal-matrix diamond composites

  • Si3N4, Al2O3, and SiC bonded diamond
  • Cu, Al, and Fe-Ni-Co matrix diamond composites

High-performance tool materials

  • WC-Co / WC-Ni cemented carbide
  • PCD / PCBN superhard tools
  • Si3N4, SiC, and Al2O3 ceramic tools

Magnetic materials

  • Nd-Fe-B and Sm-Co permanent magnets
  • Ferrite, Fe-Si-Al, and Fe-Ni soft magnets
  • Metal-ceramic soft magnetic composites

Sputtering targets

  • Refractory metal targets
  • High-purity metal and alloy targets
  • Oxide, nitride, and magnetic ceramic targets

Advanced special materials

  • Structural and functional ceramics
  • Titanium and high-temperature alloys
  • Functionally graded materials
  • Multiphase composites

Evaluation Boundary

Final feasibility depends on material composition, geometry, atmosphere window, thermal profile, target performance, and downstream testing requirements. For immature formulas or complex dissimilar joining, small-sample validation is recommended first.
