How to pick a good vacuum furnace?

Vacuum furnace varieties have a lot of, including vacuum furnace pressure type vacuum furnace, vacuum furnace, high pressure and high temperature type tubular vacuum furnace, etc., equipment, the corresponding use is also different, so how to choose a good vacuum furnace? Suitable vacuum furnace?
From the perspective of process, the design of vacuum furnace will make a good product. Vacuum heat treatment process can improve the service life of the parts, is the contemporary advanced heat treatment process, it has been generally recognized by the people.
Vacuum furnace parts heat treatment was conducted under the vacuum state, and completely avoids the problem of oxidation, the parts after vacuum heat treatment is more stable and reliable performance, has provided the safeguard for high precision workpiece.
When we were in the use of vacuum furnace, heat treatment process will face some problems in the vacuum furnace can't complete, investigate its reason, generally there are two aspects: one is the vacuum furnace manufacturer in accordance with the standards of vacuum furnace production of vacuum furnace, although the technical parameters of qualified, but not yet fully in the process of production of the vacuum furnace system to consider the heat treatment process, resulted in the vacuum furnace and heat treatment process parameters do not match. Second, vacuum heat treatment process was flawed, cannot achieve the desired results. In this respect we put the heat treatment process and vacuum furnace manufacturing organic unifies in together, the effect is obvious. Through understanding the process and details of each process, design and manufacture for vacuum furnace and heat treatment process and perfect fit, solved the trouble back at home for vacuum furnace users.
