Across International Vacuum Hot Press Furnace
 
 
 
The Vacuum Hot Press Furnace from Across International is engineered for high-precision material processing where elevated temperatures, controlled atmospheres, and uniform pressure are essential. Designed with a maximum temperature of 2100°C and equipped with advanced graphite heating technology, this system delivers stable, repeatable thermal performance for applications such as powder densification, ceramic sintering, diffusion bonding, functional material development, and research-grade high-temperature testing. Its integrated hydraulic pressing system provides up to 50 tons of pressure with exceptional accuracy, ensuring consistent compaction and high-quality sample formation.

 

To support demanding laboratory and industrial environments, the furnace incorporates a robust vacuum pump system capable of achieving ultra-high vacuum levels down to 6×10⁻³ Pa, while maintaining low leakage and stable pressure rise rates. Intelligent PID temperature control, multi-stage vacuum pumping, and optional water-cooling ensure safe, reliable, and energy-efficient operation. Combining precision engineering with user-friendly controls, the Across International Vacuum Hot Press Furnace offers a powerful, versatile solution for advanced materials research, production, and quality assurance.
