Top 10 vacuum furnace Factory in China 2026

Introduction to Vacuum Furnace

A vacuum furnace is a type of furnace in which the product in the furnace is heated in a vacuum environment. It offers several significant advantages over traditional furnaces. Firstly, the absence of air in the vacuum environment prevents oxidation, decarburization, and other chemical reactions that can occur when metals are heated in the presence of oxygen. This results in high - quality heat - treated products with excellent surface finish and dimensional accuracy. Secondly, vacuum furnaces can achieve very high temperatures, which are suitable for various heat - treatment processes such as annealing, hardening, brazing, and sintering. They are widely used in industries like aerospace, automotive, tool and die making, and electronics manufacturing.
