Furthermore, manufacturers value this technique for its efficiency and ability to produce lengths of aluminum in various shapes and sizes. The aluminum extrusion process starts with heating the aluminum billet to a pliable state. This preparation ensures the metal flows smoothly through the die. Then, it adopts the intricate contours of the mold cavity. Once extruded, the aluminum profiles undergo cooling.

It begins with a comprehensive analysis of the customer’s requirements, followed by the design and engineering of the die to match those specifications accurately. Then, the die goes for manufacturing with precision machining processes like CNC machining and electrical discharge machining(EDM)

Table: Die-making for Custom Aluminum Extrusion 

Step Description Key Considerations
Requirement Analysis Understanding the customer’s specifications and application needs. Ensure specifications are clear and comprehensive.
Die Design Creating a detailed die design using CAD software. The design must account for aluminum flow and cooling rates.
Material Selection Choosing the appropriate die steel for durability and performance. The material must withstand high pressures and temperatures.
CNC Machining Carving the die from the selected material using CNC machines. Precision machining is crucial for detail and accuracy.
Finishing and Testing Finalizing the die surface and conducting tests to ensure quality. Surface finishing and trial extrusions verify die performance.

 

What are the Aluminum Alloys for Extrusion Projects?

You can choose different Aluminum alloys for your extrusion projects based on required strength, flexibility, and corrosion resistance. Selecting the right alloy dictates the final product’s performance and durability. Therefore, manufacturers consider various factors, including mechanical properties, weldability, and finish. Moreover, this decision impacts the extrusion process and end-use.

  • Alloy 6061

It is renowned for its versatility. 6061 is a perfect blend of strength, weldability, and corrosion resistance. Meanwhile, you can use this for structural components such as automotive parts, frames, and bridges. 

  • Alloy 2024

Aluminum 2024 offers high strength and fatigue resistance in extruded parts. It’s a good choice in aerospace applications for wings and fuselage structures, where durability is paramount. However, its corrosion resistance is lower, necessitating protective coatings.

  • Alloy 7075

You can find aluminum 7075 extensively in aerospace and military applications. Its excellent strength-to-weight ratio suits components that endure high stress. Yet, it’s less weldable and more costly. Meanwhile, 7075 aluminum extrusion manufacturers consider this one as a strong aluminum alloy.

  • Alloy 6063

If you need an excellent aesthetic finish and corrosion resistance, 6063 is a good option for aluminum extrusion. It’s commonly used in architectural applications, offering a smooth surface ideal for anodizing. Here, alloy 6063 provides moderate strength suitable for windows and door frames.
