Core Technology

Automated Basket-Free Rotary Heat Treatment System

Denova combines precise thermal control with a basket-free rotary conveying system to enable continuous and automated T5/T6 heat treatment of aluminum alloy castings. Workpieces are automatically loaded, transferred, and unloaded without conventional baskets, reducing unnecessary thermal mass and simplifying material handling. For integrated solution and aging processes, waste heat from the solution treatment furnace can be recovered and reused for aging furnace heating, enabling cascading energy utilization across the heat treatment line.

Performance Benefits

Temperature Uniformity up to ±5℃

Furnace temperature uniformity can reach ±5℃, supporting stable T5/T6 heat treatment and consistent part performance.

20%+ Lower Overall Energy Consumption

Waste heat from the solution treatment furnace is reused for aging furnace heating, enabling cascading energy utilization and reducing overall line energy consumption by more than 20%.

Efficient Basket-Free Handling

Basket-free rotary conveying reduces unnecessary thermal mass and basket maintenance while supporting automated workpiece transfer and compact line integration.
