💡 What is the difference between vacuum sintering and gas pressure sintering?

HAOYUE G4 Pilot Scale Gas Pressure Sintering (GPS) Furnace

Many customers ask this before choosing equipment.

Here’s a simple breakdown:

🔹 Vacuum sintering

  • No gas pressure
  • Suitable for basic densification

🔹 Gas pressure sintering

  • High pressure (up to 100 bar)
  • Higher density
  • Better mechanical properties

👉 If you are producing tungsten carbide cutting tools,
gas pressure sintering is usually the better choice.
