28kw 600mm Multipurpose Furnace Minus 80 Deep Freezer ISO9001

The cryogenic tempering integrated furnace uses nitrogen to cool the metal surface. Nitrogen is not corrosive, but when the temperature is low, it is easy to arrange the molecules irregularly, resulting in a decrease in toughness and strength. Metal cryogenic treatment is a new process that has emerged in recent years to improve the performance of metal materials. Using liquid nitrogen as a refrigerant, cryogenic treatment of metal materials through liquid or gas methods can be used without reducing the strength and hardness of the workpiece. Significantly improve the toughness of the workpiece and increase the service life. The service life of knife and scissors products that have not undergone cryogenic treatment will be significantly reduced after refurbishment. Cryogenic treatment is not only applied to knife and scissors products, but also to molds for making knife and scissors products, and can also significantly increase the life of the mold.
