Automatic Aluminum Billet Stacking & Unstacking System
The automatic aluminum billet stacking & unstacking system is designed for automated handling, stacking, unstacking, and storage of aluminum billets after homogenization. The system integrates overhead crane handling, a stacking manipulator, conveying equipment, spacer positioning, and electrical controls to automate billet transfer from homogenizing furnace discharge through layer-by-layer stacking and storage.
| Billet Diameter | Billets per Layer | Number of Layers |
| Ø305 mm | 8 pcs/layer | 6 layers |
| Ø228 mm | 10 pcs/layer | 7 layers |
| Ø178 mm | 13 pcs/layer | 8 layers |
| Ø152 mm | 16 pcs/layer | 9 layers |
| Ø120 mm | 19 pcs/layer | 11 layers |
| Ø90 mm | 27 pcs/layer | 12 layers |
| Load capacity | Depending on configuration |
| Control system | PLC automatic control |
| Operation modes | Automatic / Manual / Remote |
| Drive system | Electric motor + Hydraulic |
| Safety protection | Safety guarding + door interlock alarm |
- Automatic billet gripping and positioning

The automatic billet stacking and unstacking system is suitable for:
- Aluminum billet homogenizing lines
- Aluminum extrusion billet production lines
- Aluminum casting and billet storage systems
- Large-scale aluminum processing plants
Conventional billet-handling processes can present several operational challenges in aluminum plants, including:
- High labor intensity during billet handling
- Inconsistent stacking quality
- Safety risks during overhead crane operation
- Low storage efficiency
- Billet damage during material handling
- Inefficient material flow from the homogenizing furnace
Huitai’s automatic billet stacking system integrates billet handling, positioning, stacking, spacer placement, transfer, and storage to address these challenges within one automated system.
Equipment is configured around the customer’s production requirements, plant layout and existing line, with installation, commissioning and technical support provided according to the project scope.
