Overview
We are a professional China manufacturer & factory specializing in custom vacuum sintering furnaces, vacuum infiltration furnaces, vacuum brazing furnaces and matched molybdenum & tungsten thermal field spare parts.
We develop and produce standard models of 500kg, 800kg and 1000kg vacuum sintering furnaces, as well as customized thermal zones and precision machined molybdenum components, including molybdenum strips, molybdenum sheets and molybdenum support posts.
Our vacuum furnaces are widely applied in NdFeB magnetic material, automotive and new energy industries. We adopt well-known brand vacuum pumps, premium sealing rings and high-precision 0.1℃ temperature controllers, to deliver reliable temperature accuracy and stable vacuum performance for your production requirements.
Vacuum Furnace Heating Chamber / Hot Zone
The heating chamber (hot zone) of our vacuum furnace consists of heating elements, heat insulation shields, furnace frame assemblies and loading trays.
We supply complete hot zone assemblies fabricated from molybdenum, tungsten and their alloys. The heating chamber is equipped with molybdenum heat shields, with multi-layer insulation structure of graphite or ceramic fiber. This all-metal or hybrid heating chamber works steadily within a temperature range from 800°C (1832°F) up to 1500°C.
Custom shapes are available upon request: circular, rectangular, vertical, horizontal and other geometric configurations.
