Industry professionals all know that vacuum hot press furnaces are widely used in the aerospace industry, mechanical equipment, metallurgy, heat-resistant alloys, carbon–carbon composite materials, semiconductor devices, and many other manufacturing fields. Let’s take a look at the main applications and features of the vacuum hot press furnace.
Main Applications of Vacuum Hot Press Furnaces:
- Suitable for high-temperature sintering and heat treatment of heat-resistant alloys, tungsten, molybdenum, high-temperature ceramics, superalloys, carbon materials, and more.
Features of Vacuum Hot Press Furnaces:
- Maximum temperature up to 2400℃, and capable of long-term stable operation at high temperatures.
- Multiple furnace configurations: top-loading, bottom-loading, vacuum or protective atmosphere options.
- Excellent sealing performance with a fully enclosed structure equipped with a vacuum pumping system and argon-purging system to ensure clean furnace atmosphere.
- Energy-efficient: induction heating directly heats graphite crucibles, resulting in high thermal efficiency and lower power consumption.
- Rapid heating efficiency—up to 600℃/hour (even faster at low temperatures).
- Short production cycle: only 24–36 hours from loading to unloading (longer for large furnaces).
- Uses infrared temperature measurement with PID segmented curve control for high-precision temperature accuracy.
- High safety: double-layer stainless steel furnace shell with water cooling; exterior surface stays below 50℃. Equipped with gas pressure, water pressure, and over-temperature alarms, as well as over-pressure venting.
- Human-machine touchscreen control with temperature recording—simple and user-friendly operation.
- Optional multi-stage filtration to protect the vacuum pumps.
- Modular control design supports multi-furnace operation using a single control unit.
