Oscillating hot pressing sintering furnace for ceramics,refractory carbide,cermets,composite powders
The oscillating hot pressing sintering furnace is a furnace that simultaneously applies an oscillating force field and a temperature field to functional ceramics, structural ceramics, refractory carbide, cermets, intermetallic compounds, refractory metals and composite powders in a vacuum, atmosphere or protective atmosphere to obtain bulk materials with high density and mechanical strength.
This product can achieve multiple functions such as oscillating sintering, vacuum sintering, atmosphere sintering, and hot pressing sintering.
The pressure has two characteristics: adjustable frequency and adjustable amplitude. Under oscillating pressure, the particle rearrangement is accelerated, and the volume shrinkage is accelerated, which can achieve the purpose of rapid densification. At the same time, it effectively improves the uniformity of the grain size of the sintered body and improves the density and mechanical properties of the sintered product.
This product can greatly improve the sintering quality, greatly shorten the material sintering time, and reduce energy consumption and production costs. This product can process high-performance ceramics and powder metallurgical products under different oscillation frequencies, different oscillation amplitudes/pressures, and different atmospheres, and can select appropriate pressure parameters and atmosphere media for various materials.
