1600°C Vacuum Atmosphere Furnace for High-Temperature Sintering in Inert Gas or Vacuum

Robust Circular Chamber for Enhanced Vacuum Performance

The circular furnace body is engineered to evenly distribute external atmospheric pressure, avoiding stress concentration and delivering greater structural stability under vacuum. Its seamless cylindrical design also ensures superior airtightness, reducing the risk of leakage and making it ideal for high-vacuum applications down to 10⁻³ Pa.
