  • The most practical safe operating procedures for vacuum furnaces, you can use them right away!

    Today, I have summarized the most practical safety operating procedures for vacuum furnaces, which can be used immediately. Let’s take a look at it together.


  • Performance characteristics of vacuum heat treatment furnace

    The vacuum heat treatment furnace uses high-quality molybdenum-doped alloy heating wire as the heating element, adopts a double-layer shell structure and a PID30 program temperature control system, phase-shifting trigger, thyristor control, and the furnace adopts alumina ceramic fiber material, which has high reflectivity and heat preservation Excellent heat insulation effect.


  • Introduction to the advantages of vacuum furnace

    Today I have sorted out some of the advantages of vacuum furnaces for your reference:1. The vacuum furnace completely eliminates the oxidation and decarburization of the surface of the workpiece during the heating process


  • Teach you perfect control of vacuum melting furnace

    Today, I will briefly talk about what problems should be paid attention to when using the vacuum melting furnace? And how to better operate the small vacuum melting furnace, let's learn together.


  • Introduction to the use and characteristics of vacuum sintering furnace

    People in the industry know that vacuum sintering furnaces are suitable for dozens of processing and manufacturing industries such as aerospace, machinery


  • Overview and technical characteristics of vacuum heat treatment furnace

    Overview of vacuum heat treatment furnace:Vacuum heat treatment is a comprehensive technology that combines vacuum technology and heat treatment. It means that all and part of the heat treatment process is carried out in a vacuum


  • Some influencing factors for choosing a vacuum furnace

    Vacuum heat treatment furnace is an important equipment to realize vacuum heat treatment. The air pressure in the furnace is lower than normal air pressure. The atmosphere in the furnace is equivalent to a kind of gas


  • Knowledge of vacuum brazing furnace

    Vacuum brazing furnace is divided into cold-wall vacuum furnace and hot-wall vacuum furnace from the basic structure. The hot-wall vacuum furnace has a simple structure and is mostly used in experiments. Most of the industrially used cold-wall vacuum furnaces are cold-wall vacuum furnaces.


  • How is the welding effect of the vacuum brazing furnace?

    The brazing method in the vacuum furnace is a relatively new brazing method that does not apply flux under vacuum conditions. Because the brazing place is in a vacuum environment, the harmful effects of air on the workpiece can be effectively eliminated
