To ensure smooth processes during sintering—such as debinding (removal of lubricants or binders), reduction, alloying, and microstructure transformation—it is necessary to precisely control sintering temperature, protective atmosphere, powder compact transport, heating rate, and cooling rate.
Therefore, high-temperature sintering furnaces should meet the following structural requirements:
- Debinding Device
- Equipped with a complete lubricant/binder removal system (commonly called a “debinding belt”).
- Gas Tightness
- Able to completely isolate the furnace interior from outside air while maintaining a controlled protective atmosphere inside.
- Controllable Temperature Zones and Atmosphere
- Each temperature zone within the furnace should be adjustable, and the sintering atmosphere must be controllable.
- Rapid Cooling Capability
- Equipped with a fast cooling system to bring sintered parts to a safe temperature for removal without oxidation.
