Vacuum Furnace (Molybdenum Foil Hot Zone)

Product Description

This high-performance vacuum furnace is designed for a wide range of thermal processing applications, including brazing, sintering, quenching, annealing, and tempering. With a maximum working temperature of 1350°C and an ultra-high-vacuum environment, it is suitable for processing components made from silver-base, copper-base, and nickel-base alloys, as well as advanced ceramics, powder-metallurgy parts, hard alloys, and precision structural components. Its combination of high vacuum integrity and excellent temperature uniformity makes it an ideal solution for industries such as aerospace, medical devices, electronics, and tooling manufacturing.

Product Highlights

• Molybdenum Foil Hot Zone — The furnace chamber is constructed with high-purity molybdenum foil lining and molybdenum strip heating elements, delivering stable and consistent performance at temperatures up to 1350°C. Molybdenum's exceptional high-temperature strength and low vapor pressure ensure a clean, contamination-free process environment.

• Superior Temperature Uniformity — Molybdenum heating strips are arranged in a circumferential layout around the furnace chamber, providing uniform radiant heating from all directions. Temperature uniformity reaches ±5°C, meeting the most demanding metallurgical specifications.

• High Vacuum Performance — The furnace is equipped with a mechanical pump + diffusion pump vacuum system, achieving an ultimate vacuum level of 7×10⁻³ Pa (no-load, cold state), effectively eliminating oxidation, decarburization, and contamination throughout the entire thermal cycle.

• Broad Process Compatibility — Suitable for a comprehensive range of thermal processes:

Vacuum Brazing — Silver, copper, and nickel-base filler metals

Vacuum Sintering — Hard alloys, ceramics, and powder metallurgy components

Vacuum Quenching — Tool steels, die steels, and high-alloy structural steels

Vacuum Annealing — Stress relief, recrystallization, and softening of precision parts

Vacuum Tempering — Post-hardening treatment for dimensional stability

• Intelligent Control System — HD touchscreen HMI with a built-in proprietary operating system and PLC automatic control, enabling precise programming of multi-segment temperature profiles, vacuum levels, and gas backfill sequences.

• Inert Gas Cooling — Inert gas (nitrogen or argon) backfill is available for accelerated cooling, allowing flexible quench rates to meet various metallurgical requirements.
