Low-pressure carburizing or low-pressure nitriding treatment is also available as an option! BMI's vacuum heat treatment furnace.
French BMI manufactured vacuum heat treatment furnace
Various vacuum furnaces tailored for different applications, ranging from parts and cutting tools for the aerospace and automotive industries, molds, and medical devices such as implants, to those for research institutions.
The OSG Group's Sanwa Seiki offers options for BMI's "Vacuum Heat Treatment Furnace" according to the type of furnace. In addition to standard heat treatment, it is also capable of performing "special treatments" such as low-pressure carburizing and low-pressure nitriding. 【Options List】 All of BMI's high-temperature furnaces can be equipped with low-pressure carburizing (ALLCARB) as an option. The low-pressure vacuum furnace (tempering furnace) B5_R series offers an option for low-pressure nitriding. It uses a reduced-pressure ammonia-based nitriding atmosphere, allowing for stable nitriding treatment in a short time. Furthermore, with the ultra-low temperature treatment (COOL PLUS) option, it reduces residual austenite and stabilizes the parts both mechanically and dimensionally. *For more details, please download the PDF or feel free to contact us.
