A complete range of Vacuum Heat Treatment Furnaces
Gas cooling Vacuum Furnaces
Ideal for high-temperature industrial processes such as vacuum hardening, vacuum brazing, and vacuum annealing. These vacuum furnaces are available in multiple configurations (horizontal, vertical, and compact) making them perfect for both large-scale production and laboratory environments. Whether you're treating large parts or working with precision components, our gas-cooled vacuum furnaces deliver consistent thermal performance, optimized cooling rates, and exceptional surface quality.
Oil Quenching Vacuum Furnaces
Designed for vacuum oil quenching processes. Available in single- or dual-chamber designs, these vacuum furnaces provide high operational flexibility and are ideal for parts requiring rapid cooling under controlled vacuum conditions. Advanced features such as low-pressure carburizing can be integrated to further enhance performance and metallurgical results.
Low-Temperature Vacuum Furnaces
BMI's low-temperature heat treatment furnaces are optimized for processes such as tempering, ageing, stress relieving, or aluminum brazing. These vacuum furnaces ensure precise thermal control and excellent temperature uniformity across all zones—critical for sensitive alloys and complex geometries operating within lower thermal ranges.
Process furnaces for Advanced Thermochemical Treatments
Our process vacuum furnaces are designed to support advanced thermochemical treatments tailored to specific metallurgical objectives. These include low-pressure nitriding, low-pressure carburizing, plasma nitriding, and sub-zero treatments. Each system is fully customizable and engineered for high precision, efficiency, and repeatability.
