It is suitable for the following processes:
– Vacuum heat treatment, such as annealing, normalizing, quenching, and tempering of materials sensitive to atmospheric environment
– Surface hardening treatment, such as vacuum surface quenching, low-pressure carburizing, etc
– Vacuum brazing, metallurgical connection of different materials
– Vacuum sintering for green parts produced by powder metallurgy (PM), injection molding (MIM,CIM), Binder Jetting printing (BJ), and other methods, including processes such as vacuuming, dewaxing, heating, sintering, and rapid cooling
-Pressure sintering, including vacuum pumping, dewaxing, heating (up to 2200 ℃), pressurization (up to 20MPa), sintering, rapid cooling, particularly suitable for the parts with high surface densification requirements. It is widely used in various processes such as powder metallurgy (PM), injection molding (MIM, CIM), additive manufacturing (AM), special manufacturing, etc
