Aluminum Extrusion Design-FAQ's

What file types can I submit for extrusion design?

We accept DWG, DXF, PDF, and IGS files for design analysis and feedback.

Can my profile be a hollow section?

Yes, both hollow and solid profiles are supported depending on your structural or thermal needs.

Why is uniform wall thickness important?

Uniform thickness prevents uneven cooling, surface distortion, and extrusion defects.

What is the recommended corner radius?

A 0.5-1 mm corner radius improves extrusion flow and tool life while reducing cracking.

How complex can my shape be?

We recommend balancing shapes and limiting tongue-to-gap ratios to avoid high die stress or tool failure.

Can I include fins or ridges for heat dissipation?

Yes, we can integrate and optimize thermal fins in your design for better cooling performance.

How do I know if my design fits your equipment?

Our team checks the profileâ€™s circumscribing circle to ensure it matches our extrusion press capability.
