Introduction of vacuum sintering furnace hardware heat shield

The heat shield is the main component of the heating chamber of the vacuum sintering furnace. Its main function is to heat insulation, heat preservation and reduce heat loss. It is also the structural basis of the fixed heater. Therefore, the selection of the structure and material of the heat shield has a great influence on the power and performance of the vacuum sintering furnace (such as vacuum degree, outgassing rate, etc.). Heat shields are basically divided into two types: metal heat shields and non-metal heat shields. Its structure is divided into full metal heat shield, sandwich heat shield, graphite felt heat shield and mixed felt heat shield. The choice of heat shield is mainly determined according to the sintering temperature, the physical and chemical characteristics of the product and the vacuum degree requirements.
