Frequently Asked Questions

What files should I send for a custom aluminum extrusion quote?

Send your cross-section drawing, 3D CAD if available, cut length, alloy and temper, critical dimensions, finish, machining requirements, quantities and delivery destination. Include mating-part details where fit matters.

Should I choose custom extrusion or a standard profile?

Compare your geometry and annual demand with available standard sections. A custom die can integrate features and reduce machining, while a standard profile may suit early validation or lower quantities. Review total project cost and timing.

What minimum quantity and lead time should I expect?

Quantity and timing depend on your profile, alloy, tooling, finish and secondary operations. Share your sample, batch and annual needs. Your quotation should confirm minimum order requirements and milestones rather than relying on a blanket figure.

Which tolerances can you achieve for my profile?

Achievable tolerances depend on section geometry, alloy, length and process. Mark critical dimensions and define the measurement method. Some mating features may need secondary machining; confirm feasibility before tooling.

Can you machine and finish my extrusions?

Review cutting, drilling, tapping, milling, anodizing or powder coating with your extrusion requirements. Define masked areas and finish allowances where they affect fits, threads or electrical contacts.

Who owns my extrusion die?

Confirm ownership, storage, maintenance, modification and replacement terms in your tooling quotation. Agree the sample approval process and how future drawing revisions will be handled.

Can you support prototypes through repeat production?

Share the quantities and purpose of each stage. Review whether a standard section with machining, a machined prototype or custom tooling best supports your validation. Agree sample acceptance before releasing repeat production.
