Electrical 500kg Aluminum Holding Furnace with 350kg Working Capacity and 0.5-3kg Dosing Range for Die Casting

WDL500KG Electrical Dosing Holding Furnace for Aluminum Alloy Casting

The WDL Dosing Furnace is an advanced machine-side holding furnace designed specifically for aluminum alloy casting processes. Combining holding and dosing feeding functions, it offers high efficiency and precision for applications in high-pressure die casting, semi-solid casting, and gravity casting industries. The furnace’s innovative features not only ensure the optimal temperature control of molten aluminum but also improve casting quality and energy savings.

Key Features of the WDL Dosing Furnace

1. Durable, Energy-Efficient Design
   The WDL Dosing Furnace utilizes a fully sealed furnace chamber with a non-crucible structure, enhancing its durability and extending its lifespan to 10-15 years. This sealed structure minimizes heat loss and results in energy consumption savings of over 70% compared to traditional open-type holding furnaces. The furnace is equipped with silicon-carbon rod heating, which is controlled by a PLC-based power amplifier for precise temperature regulation.

2. Precise Temperature Control
   The dosing furnace ensures consistent molten aluminum temperature control, with a fluctuation range of just ±1.5°C. This precision is critical for achieving the desired quality in every casting. The dosing system allows for accurate and consistent delivery of molten metal into the die-casting machine, with a customizable dosing range from 0.5 kg to 3.0 kg. The dosing accuracy is within ±1.5%, which is essential for producing high-quality aluminum castings.

3. Hydraulic Lift and Tilting Function
   The hydraulic lift system allows the furnace to adjust its height according to the die-casting machine’s injection position, providing greater flexibility. Additionally, the tilt function makes material changeover and cleaning faster and more efficient, significantly reducing labor intensity and downtime. This feature makes the WDL Dosing Furnace a highly productive solution for aluminum alloy casting.

4. Pneumatic Dosing System for High Accuracy
   The dosing furnace is equipped with an advanced pneumatic dosing system that feeds molten aluminum directly into the die-casting mold. This system ensures fast, precise dosing while maintaining the quality of the aluminum liquid. The aluminum’s surface oxide layer is not disturbed during feeding, ensuring the purity and consistency of the metal.

5. Online Degassing Function
   The online degassing feature of the WDL Dosing Furnace removes impurities from the aluminum alloy, which is crucial for achieving high-quality, gas-tight castings. This function is especially important for products requiring very high air-tightness and consistency in metal properties.
