A "mold heating/holding furnace," also known as a "die heating/holding furnace" or "billet heater," is a specialized type of industrial furnace used to preheat or maintain the temperature of molds or dies used in various aluminum forming processes. These furnaces play a crucial role in ensuring the proper working temperature of molds and dies, which is essential for achieving accurate and consistent shaping of aluminum billets or ingots during processes like extrusion and die casting.
Usage of Mold Heating/Holding Furnace in the Aluminum Industry:
- Preheating Molds: Before starting the aluminum forming process, the mold heating furnace is used to preheat the molds or dies to the desired working temperature.
- Maintaining Temperature: During the aluminum forming process, the furnace is used to hold the molds or dies at a constant temperature to ensure consistent product quality.
- Die Heating in Extrusion: In the extrusion process, the furnace is used to heat the die, allowing the aluminum billet to flow smoothly through the die cavity.
- Die Heating in Die Casting: In die casting, the furnace is used to preheat the mold or die, ensuring proper metal flow and reducing the risk of defects in the cast parts.
How Mold Heating/Holding Furnace Works in the Aluminum Industry:
- Loading: The molds or dies are loaded into the heating/holding furnace.
- Heating: The furnace uses a heat source, such as gas burners or electric heating elements, to raise the temperature of the molds or dies to the desired level.
- Temperature Control: The furnace is equipped with temperature control systems to maintain the molds or dies at the required working temperature.
- Holding Time: Once the desired temperature is reached, the molds or dies are held at that temperature for a specific duration to ensure thermal stability.
- Unloading: After the preheating or holding period is complete, the molds or dies are unloaded from the furnace and used in the aluminum forming process.
