Unidirectional or bidirectional high temperature and pressure sintering furnace for material high-density processing
Unidirectional or bidirectional high temperature and pressure sintering furnace for material high-density processing
This equipment is widely used in efficient densification sintering of various ceramics, alloys, and composite materials. The equipment size can be customized, the pressure head material can be graphite or TZM, and the pressurization method can adopt upper and lower pressure heads for unidirectional pressure or bidirectional pressure.
The sintering process can be divided into two categories: unpressurized sintering (sintering without external pressure) and pressurized sintering (sintering with external pressure).Pressure sintering is the process of applying high temperature and external pressure to loose powder or powder compacting.
Hot-pressing Sintering, Hot Pressing Sintering, HPS) is in the process of Sintering and exert a certain external force (according to the strength of the mould material can withstand, general pressure in the 10 ~ 40 mpa), make the material flow acceleration, rearrangement and densification.The temperature of hot pressing sintering is about 100℃~150℃ lower than that of normal pressure sintering, but the driving force of hot pressing sintering is 20~100 times larger than that of normal pressure sintering.
Advantages
-
During hot pressing, the powder is in a thermoplastic state, which results in low deformation resistance and makes it easy for plastic flow and densification to occur. Consequently, the required forming pressure is only 1/10 of that in the cold pressing method. This enables the formation of large-sized products such as Al₂O₃, BeO, BN, and TiB₂.
-
The simultaneous application of heating and pressurization facilitates the mass transfer processes of powder particles, including contact, diffusion, and flow. This reduces the sintering temperature and shortens the sintering time, thereby inhibiting grain growth.
-
The hot-pressing method allows for the easy production of sintered bodies with near-theoretical density and porosity close to zero. It also enables the achievement of a fine-grained structure, the realization of crystal orientation effects, and the control of composition changes in sodium systems containing high vapor pressure. As a result, products with excellent mechanical and electrical properties can be easily obtained.
-
It is capable of manufacturing products with complex shapes and precise dimensions.
