Vacuum furnace
aboutWhat is a vacuum furnace?
A vacuum furnace is a type of heating equipment used to perform heat treatment processes in a vacuum atmosphere. This type of furnace is designed to minimize the effects of oxidation and minimize the formation of surface oxide scale on treated products, particularly steel. The use of a vacuum atmosphere also results in degreasing and degassing of organic matter on the surface of the product, leading to restored original surface brightness after treatment. Sun Furnace Co., Ltd. a manufacturer of gastight vacuum furnaces, offers custom-made furnaces to meet the specific needs of its customers.
