Nous n'utilisons pas d'outils de devis automatisés en ligne, car ils sont très imprécis. Les plateformes de devis en ligne reposent uniquement sur des calculs basés sur des montants de coupe et des coefficients fixes, et ne tiennent pas compte des nuances de traitement réelles, comme la déformation du matériau après le traitement thermique, les exigences de tolérance strictes, le meulage après le traitement thermique, etc. Par conséquent, les calculs de prix automatisés peuvent entraîner des inexactitudes et, en fin de compte, augmenter vos coûts.
Mais chez DEK, vous pouvez être tranquille !

What is Aluminum Extrusion Machining?
Aluminum extrusion machining is the process of creating custom aluminum profiles by pushing heated aluminum through a shaped die, then precisely cutting and machining the extruded pieces. This combination allows you to produce strong, lightweight components with complex cross-sections. Machining operations—such as drilling, tapping, milling, and finishing—are added after extrusion to meet exact specifications, improving function, fit, and appearance.
It is a versatile manufacturing method that supports both prototyping and large-scale production. With the ability to work in a wide range of alloys, it can meet specific requirements for strength, corrosion resistance, and thermal performance in industries from aerospace to consumer products.
What are the Advantages of Aluminum Extrusion Machining?
Aluminum extrusion machining combines the flexibility of extrusion with the precision of CNC machining, offering:
- Complex shapes with consistent cross-sections
- High strength-to-weight ratio in parts
- Reduced material waste and cost efficiency
- Excellent corrosion resistance with suitable alloys
- Smooth finishes with optional anodizing or coating
- Ability to integrate multiple features in one profile
- Shorter production times than full machining
- Reliable, high-quality components
When Do You Need Aluminum Extrusion Machining?
You need aluminum extrusion machining when your design requires long, uniform profiles with detailed machining features. It’s ideal for frames, enclosures, heat sinks, rails, and structural components across industries like aerospace, automotive, electronics, and construction. This method is especially useful when you want to balance lightweight design, structural strength, and precise functionality, without excessive machining time or cost.
It is also a practical choice when projects demand consistent part-to-part accuracy across high volumes. By combining extrusion with precision machining, you can streamline assembly, reduce secondary operations, and achieve repeatable quality even in complex designs.
