Denova Develops Integrated “1+2” Molten Aluminum Supply System for Doli Technology’s 9,200T Die Casting Cells

On August 8, 2024, Doli Technology held the ignition ceremony for its 9,200T die casting cell “1+2”molten aluminum supply system at its Changzhou production base.

The innovative system adopts a new configuration combining one tower melting furnace with two dosing furnaces, and was specifially designed to provide molten aluminum supply for two 9,200T ultra-large die casting cells. Developed by Denova Thermal Technology (Suzhou) Co., Ltd. (“Denova”), the system represents an integrated solution for large-scale die casting applications, supporting stable and efficient aluminum manufacturing processes.

The system consists of one DMFS 6000-12000 melting furnace and two DDI 6100 dosing furnaces. Integrating melting, holding, molten aluminum treatment, and transfer functions, the melting furnace achieves a melting capacity of 6 tons per hour and a holding capacity of up to 12 tons. Equipped with dedicated molten aluminum treatment pools and transfer zones, the system ensures stable aluminum quality and continuous molten aluminum supply.

The two dosing furnaces, each with a 6-ton holding capacity, are symmetrically positioned on both sides of the two die casting cells, enabling synchronized molten aluminum delivery and supporting efficient production operation.

Denova’s integrated molten aluminum supply system further enhances automation through intelligent materials transfer control. The transfer section of the melting furnace is positioned between the two dosing furnaces and connected through an automatic rotary launder system. The patented opening and closing mechanism automatically adjusts according to production requirements and enables precise molten aluminum transfer to the designated die casting unit.

When the dosing furnace detects insufficient molten aluminum, a signal is automatically sent to the transfer pump, allowing treated aluminum from the melting furnace to be quickly transferred through the launder system. This fully automated process minimizes manual intervention, enabling the complete die casting island to operate with only one operator.

Doli Technology is a leading automotive component and stamping-welding parts manufacturer listed on the Shenzhen Stock Exchange. In recent years, the company has actively expanded into integrated die casting and introduced multiple ultra-large die casting cells. With eight 6,100T-9,200T die casting cells deployed across its production bases in Jiangsu and Anhui, Doli Technology has become one of the leading manufacturers in large-scale integrated die casting applications.
