PQS series small real air quenching furnace is a kind of miniaturized vacuum furnace, mainly used for quenching, tempering, annealing, solution and aging treatment of materials. Through precise temperature control, vacuum environment technology, combined with inert gas (such as nitrogen or argon) through optimized airflow design forced cooling, modular design and intelligent control, it significantly improves the mechanical properties, physical properties and dimensional stability of parts, and expands the application range of materials, with high precision, low deformation, no oxidation, intelligence and high adaptability as the core advantages. Meet the needs of high-end manufacturing, widely used in aerospace, precision mold, medical equipment, scientific research and other fields.
