Vacuum Sintering Furnace
Xiamen Dexing Magnet Tech. Co., Ltd. is a technology-based enterprise specializing in the research and development and manufacturing of vacuum equipment. Over the years, Dexing Vacuum has developed various furnace types with temperatures ranging from 100°C to 2200°C and loading methods ranging from horizontal loading to large vertical bottom loading.
It adopts a unique internal (external) airflow circulation method and a larger vacuum unit, with the characteristics of uniform cooling, fast speed, good furnace temperature uniformity, large exhaust volume, uniform and controllable temperature, high vacuum and no leakage and etc. The cooling methods are divided into two types: internal circulation (DXRVSX) and external circulation (DXRVS).
The control system is PLC, and the temperature is controlled by an intelligent temperature controller. The control is accurate and the degree of automation is high. It can realize full-automatic/manual disturbance-free switching and abnormal alarm function. The operation is simple and reliable.
