This fully automatic nano silver/nano copper positive pressure sintering furnace is primarily designed for mechanical pressure sintering. For the pressure application unit, a precision hydraulic control system is adopted in this design to achieve high-precision pressure exertion. A vacuum-sealed structure is employed for the overall furnace chamber and structural design. The sintering process can be conducted in a vacuum environment or a protective atmosphere filled with two or more inert gases, which enhances the product sintering quality. The complete equipment consists of the following systems: automatic loading and unloading system, pressure application system, vacuum system, heating system, temperature control system, cooling system, etc. The sintering process includes two stages: pre-pressing and main pressing.
