We deal with products made by vacuum furnaces every day, such as gears in car transmissions, special hard drill bits used in industry or DIY. Without vacuum, these high-strength materials are difficult to produce. Let's take a look at the vacuum applications in vacuum furnaces.

The workpiece is heated in the vacuum furnace, and oxygen is isolated through the vacuum environment to avoid oxidation of the workpiece. Therefore, the application of the vacuum furnace is also very wide, which can be used in the vacuum sintering of hard alloy production in the cutting tool industry, the vacuum brazing of the vacuum switch room production in the electrical industry, and the vacuum quenching for the high alloy steel necessary for the manufacturing of gear in the automobile industry.

What are the advantages of using vacuum in vacuum furnace? Not only can the aforementioned oxidation be avoided, but also the quality of the vacuum-sintered surface can be improved, avoiding reworking of the workpiece and resulting in higher strength, density, and lower porosity. Vacuum brazing, for example, improves joint quality and ensures high repeatability of the process. For vacuum quenching, the surface quality can be greatly improved and the possibility of workpiece deformation can be reduced. The vacuum furnace technology ensures the surface quality of the workpiece and enables the workpiece to be nitrized directly after hardening.

Vacuum technology makes possible many technologies considered impossible by traditional technology. The application of vacuum furnace is such an example. Common applications of vacuum furnaces include brazing, sintering, annealing, degassing, drying, tempering, welding, quenching, and hardening. Vacuum furnaces can also be used for metal injection molding (MIM) or ceramic injection molding (CIM) as well as metallization, silication, carbonization and other industrial processes. Different vacuum furnaces have different applications.
