P3V Vacuum Hot Pressing 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.

Efficient temperature rise and fall capability: The maximum temperature rise rate of the empty furnace can reach up to 20C/min, and it is fully adjustable from 1 to 20C/min, meeting the sintering process requirements of different materials. The high-temperature resistant heat shield design enhances the cooling efficiency, significantly improving the equipment turnover rate.

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

Excellent temperature uniformity: In the constant temperature zone (after holding at 1000C for 1 hour), temperature is measured at 5 points, achieving a temperature uniformity of +/-5C and a temperature control accuracy of +/-1C. Precise temperature control throughout the entire process ensures stable sintering quality of the material.

High mechanical pressure (standard version 1000kN / 100T, enhanced version 1500kN / 150T): Compared to low-pressure equipment, high pressure can significantly enhance the densification ability of materials, especially for superhard ceramics (B4C, SiC) and nanometer powder sintering, effectively eliminating internal pores and improving the mechanical properties of products.

High-precision pressure control: Utilizing a servo hydraulic system, the pressure control accuracy is maintained at <=+/-3 per milleFS (full scale), ensuring stable pressure during the sintering process and preventing material defects.

Multiple security protections: HMI+PLC+PID full-parameter linkage control, real-time monitoring and adjustment of process parameters such as temperature, vacuum degree, and pressure; multi-level safety interlock, immediate alarm and shutdown protection for abnormal conditions such as overtemperature, overpressure, water failure, and overcurrent; independent overtemperature monitoring + power-off protection mechanism, providing dual safeguards for equipment and personnel safety.

Excellent sealing performance: The dynamic pressure head is sealed with welded metal bellows to ensure no leakage in vacuum/atmospheric environments; the pressure rise rate is <=0.5Pa/h (in the cold state of an empty furnace), reducing gas pollution (oxidation/nitridation), lowering the frequency of vacuum pump replenishment, and extending equipment life.

Energy-saving and environmental protection advantages: Rapid temperature rise and fall, 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. The furnace body features a double-layer water cooling design, ensuring the furnace wall temperature remains at or below 55C, balancing operational safety and energy utilization efficiency.

Wide applicability: It is suitable for hot-press sintering, densification treatment, and powder metallurgy of materials such as ceramics (B4C, SiC, BN), graphene composites, and high-temperature alloy powders, meeting the needs of scientific research and industrialization.
