Overview
Pressure sintering furnace series are designed to integrate the functions of pressure de-waxing, vacuum de-waxing, vacuum sintering, TORVAC, partial pressure sintering, pressure sintering, atmosphere sintering, fast cooling and etc. It is mainly used in the production of high-performance cemented carbide materials.
Advantages
Our pressure sintering furnace has the following advantages.
①High sintering density: The material in the pressure sintering furnace is sintered under high temperature and high pressure conditions, which helps to increase the sintering density of the material, thereby improving the mechanical properties of the material.
②Atmosphere control: The pressure sintering furnace has an atmosphere regulation function, which can stabilize atmosphere in the furnace, so as to better control the product quality.
③Pressure control: The pressure in the pressure sintering furnace can be controlled to achieve constant pressure sintering, so as to better optimize the sintering process.
④ Our pressure sintering furnace has high automation degree, easy to operate, with functions of manual operation, automatic control and locking, good flexibility, can achieve remote operation and remote diagnosis functions.
