The push rod powder metallurgy sintering furnace is a continuous operating furnace. It is a specialized equipment for sintering iron-based powder metallurgy products with atmosphere protection, suitable for pressing and forming. It has a high sintering yield and industrial efficiency, and the equipment operates smoothly, safely, and reliably. The heating chamber can be filled with protective gases to prevent oxidation and carburization during heating, thus enabling the workpiece to achieve good mechanical and physical properties.
