Extrusion
Aluminum extrusion is a manufacturing process in which pre-heated aluminum is forced through a die or mold to create a continuous shape with a specific cross-section. This method allows for the production of aluminum profiles with complex and uniform shapes, such as tubes, bars, frames, and other structures.
Stages
Loading Area
This stage of the process involves preparing the aluminum billet for extrusion.
- Bar Loader
- Ingot Furnace
- Hot Shear
Press Area
In this stage, the aluminum billet is extruded to obtain a profile.
- Billet Loader
- Extrusion Press
- Control Handling
Post-Extrusion Processing
This stage includes the transportation and treatment of the material to enhance its properties after extrusion.
- Cooling Table
- Pullers
- Tables
- Profile Saw
- Stop
- Profile Stacker
- Stacker / Destacker
- Aging Furnace
Auxiliary Equipment
This equipment adds value to the final product or preserves the lifespan of certain elements involved in the extrusion process.
- Die Oven
- Automation Modules
- Scrap Compactor

Press Outlets
The extrusion press outlet is the opening or die through which heated aluminum is forced to adopt a specific shape during the extrusion process. It is a critical component of the extrusion machine, designed according to the shape of the desired profile, which can range from simple round bars to complex shapes like window frames or rails.
Made from high-strength steel, the outlet is configured to allow aluminum, when passing through it under high pressure, to adopt the intended design for the extruded profiles. These dies can vary in size, shape, and complexity, depending on the specific requirements of the final product.
Importance in Aluminum Profile Manufacturing
- Precision in Shapes: The press outlet defines the exact geometry of the aluminum profile, enabling the production of pieces with complex and precise shapes.
- Repeatability: It ensures that all extruded profiles maintain the same shape and dimensions, which is crucial for mass production.
- Customization: Custom designs can be created in the die to produce tailor-made profiles, adapted to specific industrial or architectural needs.
- Product Quality: A well-designed press outlet guarantees that the extruded profiles are uniform, with clean edges and no defects, thus improving the final product quality.
