D2 Vacuum Diffusion Welding Furnace

Highly integrated design: Adopting a horizontal, side-opening, integrated machine structure, it optimizes material loading and unloading accuracy, facilitates operation, and allows for flexible equipment movement, significantly improving efficiency and space utilization.

High efficiency heating and cooling performance: Rapid heating: It takes only 90 minutes to heat from 10C to 2000C (with an average heating rate of 22.22C/min), which shortens the process time by 50% to 70% compared to traditional equipment and significantly reduces energy consumption;

Rapid cooling: It takes only 387 minutes to cool down from 2000C to 50C (with an average cooling rate of 5.04C/min), significantly improving equipment turnover rate (actual measurement data report available).

Optimized thermal field design: The heating chamber undergoes thermal simulation calculations to ensure temperature uniformity. It adopts a modular heating element combined with an efficient insulation layer design to reduce heat loss and enhance the energy efficiency ratio.

Excellent temperature uniformity: After maintaining a constant temperature of 1000C for 1 hour, temperature measurement at 5 points shows a uniformity of +/-5C, ensuring stable sintering quality of the material.

Electric cylinder pressure (Standard version 5T/50kN, Plus version 10T/100kN): With 5T/10T high-pressure capability, the system dramatically enhances diffusion bonding, delivering stronger interfaces, superior densification, and high-efficiency atomic-scale metallurgical bonding.

High-precision pressure control: Using a servo electric cylinder system, the pressure accuracy is <=+/-1 per milleFS (full scale), ensuring stable pressure during the sintering process and avoiding material defects.

Multiple security protections: HMI+PLC+PID pressure sensing control enables real-time monitoring and adjustment of process parameters; multi-level safety interlocking prevents abnormal conditions such as overpressure and overtemperature, ensuring the safety of equipment and personnel.

Excellent sealing performance: The dynamic pressure head is sealed with welded metal corrugated pipes to ensure no leakage in vacuum/atmospheric environments; the pressure rise rate is <=2Pa/h (empty furnace in cold state), reducing gas pollution (oxidation/nitridation), lowering the frequency of vacuum pump replenishment, and extending equipment life.

Energy-saving and environmental protection advantages: Rapid raising and cooling temperature design, coupled with efficient insulation, can reduce electric energy/gas consumption by over 20%. The low leakage rate design minimizes the waste of protective gas, thereby lowering operating costs.
