This furnace is mainly for mechanical pressure sintering. For the pressure application unit, a precision pressure control system is adopted in this design to achieve high-precision pressure exertion. A vacuum-sealed structure is applied to the overall furnace chamber and structural design. The sintering process can be carried out in a vacuum environment or two or more types of atmospheres, which improves the product sintering quality. The complete equipment includes the following systems: transmission system, lifting system, pressure application system, vacuum system, heating system, temperature control system, cooling system, etc. The process is divided into two stages: pre-pressing and main pressing.
