To build a complete aluminium extrusion facility, you need a full set of aluminium extrusion equipment that covers the entire process, from heating and extrusion to cooling, straightening, and finishing.
Core Equipment List:
- Extrusion press machine
- Billet heating furnace
- Extrusion die system
- Run-out table
- Cooling system
- Stretching machine
- Cutting system
- Aging furnace
In simple terms, a complete aluminium extrusion plant setup includes extrusion machinery, heat treatment systems, and material handling and protection systems.
Overview of the Aluminium Extrusion Process
Before selecting equipment, it is important to understand the extrusion workflow. This helps clarify the role of each machine in the production line.
Step-by-Step Process:
- Billet Heating
Aluminum billets are heated to approximately 400–500°C to improve plasticity - Extrusion
The heated billet is forced through a die using an extrusion press machine - Profile Handling
Hot aluminum profiles are transferred via the run-out table - Cooling
Profiles are cooled using air or water to control material properties - Stretching
Internal stresses are removed and straightness is improved - Cutting
Profiles are cut to the required length - Aging
Heat treatment enhances mechanical strength
Each stage relies on specific aluminum extrusion process equipment to ensure stable and efficient operation.
Core Aluminium Extrusion Equipment Explained
1. Extrusion Press Machine
The extrusion press machine is the core of the entire production line.
Functions:
- Generates extremely high pressure, often several thousand tons
- Forces heated aluminum through the die
Types:
- Direct extrusion
- Indirect extrusion
The press capacity determines production output and the size range of profiles.
2. Billet Heating Furnace
The billet heating furnace ensures billets are heated evenly before extrusion.
Key considerations:
- Temperature accuracy
- Heating uniformity
- Energy efficiency
Poor temperature control can lead to extrusion defects.
3. Extrusion Die System
The die system defines the final shape and precision of the product.
Functions:
- Controls cross-sectional geometry
- Affects surface finish
- Determines dimensional tolerances
High-quality dies are essential for consistent production.
4. Run-Out Table
The run-out table supports and transports high-temperature profiles after extrusion.
Key features:
- Heat resistance
- Stable conveying
- Prevention of deformation
It plays a critical role between extrusion and downstream processes.
5. Cooling System
The cooling system directly impacts final material properties.
Methods:
- Air cooling
- Water quenching
Cooling rate influences strength and microstructure.
6. Stretching Machine
The stretching machine removes internal stress.
Functions:
- Improves straightness
- Enhances dimensional stability
7. Cutting System
The cutting system ensures precise length control.
Requirements:
- High accuracy
- Automated operation
8. Aging Furnace
The aging furnace is used for heat treatment.
Functions:
- Improves mechanical properties
- Stabilizes material structure
Supporting Equipment in Aluminium Extrusion Lines
In addition to core machines, supporting systems are equally important.
Key Supporting Systems:
- Conveyor systems
- Automation control systems
- Material handling systems
Importance of Heat-Resistant Materials
During extrusion:
- Aluminum profiles can exceed 500°C
- Surfaces are highly vulnerable to scratches and contamination
This makes high-performance, heat-resistant materials essential.
