Four à chargement par le bas
Bottom-Loading Furnace are high-temperature furnaces suitable for large workpieces and mass production, and are widely used in sintering, recuit, and material handling processes. This equipment uses an electric lifting mechanism for loading and unloading, making it suitable for materials that are difficult to handle manually or that are large in size.
In actual use, the workpiece enters the furnace chamber via the lifting platform. The heating process is stable and reliable, improving production efficiency and reducing human error. This equipment is suitable for industrial production, as well as laboratory and research applications. Smaller units are also commonly used in denture processing, zirconia crown sintering, and powder material processing.
