What is Custom Aluminum Extrusion?

Think of custom aluminium extrusion like pushing Play-Doh through a shaped mold, but with aluminum and industrial precision. It’s a manufacturing process where we heat aluminum until it’s soft and pliable, then force it through a specially designed die (basically a custom-shaped opening) to create exactly the profile you need.

The beauty of this process is that it’s completely tailored to what you’re trying to build. Need a window frame with specific grooves? A heat sink with particular fins? Or maybe a structural beam that fits perfectly into your design? Custom extrusion lets us create aluminum pieces that match your exact specifications – the right shape, the right size, and with the properties your project demands.

Benefits of Aluminium Extrusion

Step 4: Rectifying (straightening) the aluminum profiles — a step that ensures the extruded parts are straight with no twist or distortion
Step 5: Cutting to length and
Step 6: Surface treatment
Step 7: Quality checking – Packing & Delivery

What aluminum alloys can be used for custom extrusion?

Answer: We can extrude most aluminum alloys including 6061, 6063, 6005, 6082, 7075, and a few more 7000 series alloy. The most popular choices are 6061 (structural applications) and 6063 (architectural applications) due to their excellent extrudability and strength-to-weight ratio. Alloy selection depends on your specific requirements for strength, corrosion resistance, and machinability.

What tolerances can be achieved with custom aluminium extrusion?

Answer: Standard custom aluminium extrusion tolerances are ±0.1mm to ±0.25mm depending on the dimension and complexity. Critical dimensions can achieve tighter tolerances of ±0.05mm with precision dies and careful process control. Wall thickness tolerances typically range from ±0.1mm to ±0.15mm for most applications.

Can you create complex shapes with custom aluminum extrusion?

Answer: Yes, we can create highly complex aluminum extrusion profiles including multi-chamber designs, intricate internal channels, and asymmetrical shapes. Our advanced die design capabilities handle hollow profiles, thin walls (minimum 1mm), and complex geometries that would be impossible with traditional manufacturing methods.

What surface finishes are available for custom extruded aluminum?

Answer: We offer comprehensive surface finishing including mill finish, anodizing (clear, black, bronze, custom colors), powder coating , painting, brushing. Anodizing provides excellent corrosion resistance while powder coating offers durability and aesthetic appeal. Custom color matching is available for brand consistency.

Anodizing
Enhances corrosion resistance and allows for various color finishes.

Powder Coating 
Provides a durable, uniform finish available in a wide range of colors.

Electrophoresis Coating
smooth,corrosion-resistant finish Long-lasting gloss and color retention

PVDF offers superior weather resistance and color retention | Wood Grain provides natural wood-like appearance

How do you ensure quality in custom aluminum extrusion?
