WDL-CDJ-5000 Immersion Electric Melting Furnace with 5000 kg Capacity and 70 kW Heating Power for Precise ±2°C Temperature Control

WDL-CDJ-5000 Immersion Electric Melting & Holding Furnace – Vertical Insertion Type for Aluminum Alloy Die Casting

Product Overview

WUXI WONDERY INDUSTRY EQUIPMENT CO., LTD. introduces the WDL-CDJ-5000, a high-efficiency immersion melting and holding solution for aluminum alloy die-casting. Utilizing a unique vertical insertion design, this system heats the molten metal directly from the inside, delivering over 30% higher thermal efficiency than traditional radiant systems.

Industry Challenges & Causes

• Problem: High Energy Wastage. Conventional furnaces rely on radiation, which leads to massive heat loss during the transfer process.

• Cause: Indirect Heating Methods. Heating the air inside the furnace to reach the metal is inefficient and energy-intensive.

• Problem: Excessive Oxidation & Dross. Surface heating in oxygen-rich environments leads to high metal loss and poor melt quality. 

• Cause: Surface Overheating. Standard methods create temperature imbalances at the metal surface, accelerating oxidation.

 Our Solution

• Direct Immersion Heating: By heating from within the melt, the system achieves near-perfect thermal transfer and stable performance.

• Precision Temperature Stability: Maintains holding accuracy at ±2°C with an internal oxygen level of <2%, drastically reducing dross formation.

• Advanced Smart Controls: Integrated with  PLC, Keyence laser level detection, and remote LED digital displays for real-time monitoring.

• Superior Multi-Layer Insulation: Uses nano-insulation boards from Japan and Sweden, keeping the external temperature rise below 20°C above ambient.

FAQ

• Q: Is heating element replacement difficult?

  A: No. The vertical insertion design allows for easy replacement on-site after basic training, minimizing downtime.
  •  

• Q: How does this save energy compared to radiant furnaces?

  A: By heating the liquid directly rather than the air, it eliminates heat loss through the furnace lining and surface radiation.
