What's the Aluminum Extrusion Process?
Aluminum extrusion is the process of pushing a heated aluminum billet through a custom die to form profiles with a specific corss-sectional shape. At RapidDirect, we follow a standard, proven production flow:
It begins with die machining, solid , hollow, or semi-hollow, and billet preheating, typically 400–500°C. Aluminum is then extruded—either direct or indirect, hot or cold — depending on the aluminum alloys and end use.
Once extrusion, the profile is cooled, stretched, and cut to size. Additional steps such as aging for strength and hardness, surface finishing for appearance and functionality, or assembly can be applied as needed. Each custom aluminum extrusion go through inspection and packaging before delivery.

FAQs
What’s the typical tolerance range for custom aluminum extrusions?
Tighter tolerances cost more to manufacture. Precision tooling and extra inspection steps increase production expenses.
Pick tolerances that match your project needs. Standard tolerances work for most applications and keep costs down. Use tighter tolerances only when parts must fit precisely together.
RapidDirect follows ISO 9001-C standards. Critical dimensions are controlled within ±0.1 mm, while other dimensions are held to ±0.15 mm. RapidDirect helps you pick the right tolerance specification that works for your custom aluminum extrusion project without paying for precision you don’t need.
Any non-welding frame or gantry options besides aluminum extrusions?
Steel Tubing with Mechanical Connections
Steel tubing can be fastened together without welding using corner bracecs with metal farming scrrews or mechanical connectors and clamps.
Alternative Methods
Mechanical fasteners and adhesives work as welding alternatives. Steel profiles offer higher strength than aluminum, but need more complex assembly. For CNC grantries, steel tubing with brackets works, thouth aluminum extrusions remain easier to assemble.
What factors determine the wall thickness of custom aluminum extrusions?
The wall thickness of an aluminum extrusion depends on several practical considerations:
- Aluminum Grade– Softer alloys may need thicker walls for strength, while stronger alloys can support thinner sections.
- Profile Design– Shapes with deep channels, curves, or unsupported spans may require more thickness for stability.
- Press Capability – The size and tonnage of the press influence how thin or thick a section can be reliably formed.
- सतह परिष्करण– Coatings or anodizing may affect minimum wall thickness to avoid distortion or uneven treatment.
- Dimensional Tolerance – Stricter tolerance limits often lead to thicker walls to ensure consistent output during cutting or machining.
Wall thickness is typically set during the design stage, balancing strength, weight, and cost based on how the part will be used.
What wall thickness is generally recommended for custom aluminum extrusions?
A typical recommended wall thickness falls between 1.0 mm and 2.5 mm.
- For structural or load-bearing parts, thicker walls (2.0 mm or more) offer better strength and rigidity.
- For lightweight or decorative components, thinner walls (around 1.0 mm) are often sufficient.
- Minimum feasible thickness also depends on the alloy, shape complexity, and press capacity.
The final choice should balance mechanical needs, weight, and cost, based on the extruded aluminum part’s application.
Do you support prototyping for aluminum extrusion projects?
Yes, Termite Precision provides prototyping and small-batch aluminum extrusion services. We can produce sample parts for testing and validation before full production runs.
Our prototyping service helps you:
- Test fit and function before committing to large quantities
- Verify dimensions and tolerances meet your specs
- Evaluate surface finishes and material properties
- Make design changes early in the development process
What’s the typical cost for custom aluminum extrusion services?
Costs depend on a few main things:
Material Type Different aluminum alloys cost different amounts. Common ones like 6061 and 6063 are cheaper than specialty metals.
Part Size Bigger profiles use more material and might need larger presses, which costs more.
Design Complexity
- Simple shapes are cheaper to make
- Complex cross-sections need expensive tooling
- Tight tolerances take more time and inspection
Other Things That Affect Price
- How many you order – bigger orders cost less per piece
- Surface finishes you want
- Tooling and die costs for new profiles

Any tips for keeping extrusion production cost-effective?
Start with smart design choices to cut costs. Keep wall thickness uniform since varying thickness makes tooling harder and more expensive. Use simple radius corners instead of sharp angles, and make designs symmetrical when possible. Try to minimize channels and screw slots, and avoid deep, narrow channels that are hard to form during extrusion.
Choose standard aluminum alloys like 6061 or 6063 rather than specialty metals. Order larger quantities to spread tooling costs across more parts. Use standard tolerances unless tight ones are really needed for your application. Pick simpler surface finishes and consider using existing die profiles if they work for your project.
Plan your design carefully and stick with it. Changes after tooling is made get expensive fast. Work with your aluminum extrusion supplier early in the design phase so they can spot potential cost issues before you commit to expensive tooling.
Is it possible to recycle aluminum extrusions?
Yes, aluminum extrusions are 100% recyclable without losing strength or quality. Recycling cuts manufacturing costs and reduces carbon footprint compared to making new aluminum. You can reuse aluminum extrusions many times, making them good for eco-friendly projects while keeping the same performance.
What kinds of extrusion dies are used in producing custom aluminum profiles?
Three main types of dies:
Solid Dies. Used for simple, solid profiles without any hollow sections or internal cavities. These are the most basic and cost-effective dies.
Hollow Dies. Create profiles with enclosed hollow sections or tubes. These dies are more complex because they need mandrels to form the internal cavities.
Semi-Hollow Dies. Make profiles with partially enclosed sections, like C-channels or angles with slots. These fall between solid and hollow dies in terms of complexity and cost.
What're standard size for T-slot framing?
10mm x 10mm, 20mm x 20mm, 30mm x 30mm, 40mm x 40mm, 45mm x 45mm, 50mm x 50mm, 60mm x 60mm, 80mm x 80mm, 100mm x 100mm, 160mm x 160mm.
These are typical profiles for T-slot aluminum extrusions used in framing and assembly applications. Different industries like windows, doors, or structural construction may use different standard sizes based on their specific requirements.
