Downloads & free DFM review
Grab the checklist to design better profiles, request CAD/STEP models for your section, or send your drawing for a free DFM review — no commitment required. Everything here is built to speed up your RFQ and lower the risk of a new tool.
Aluminum Extrusion Design Checklist (PDF)
One page covering wall thickness, fillets, fin limits, tongue ratio and tolerances — the five rules that avoid most rework. Print it before you draft a section.
Download (email gate)CAD / STEP models
Engineers searching for an aluminum profile CAD model can request STEP files for standard sections and a parametric draft of your custom section to drop into the assembly. The model is built from the same datum we extrude to, so it matches the finished part.
Request CAD (email)Capability sheets
Extrusion, CNC, bending, welding, anodizing and powder coating specs in one PDF — press range, typical tolerances and finishes at a glance for your supplier-review file.

Send your drawing; our engineers return alloy, DFM notes and a pricing range within 24h. No obligation to order — the lowest-friction way to de-risk a new profile.
Send drawing →What the design checklist covers
The checklist is the five checks we run before quoting tooling. Get these right on the drawing and lead time drops:
Wall thickness
Keep walls uniform; practical minimum around 1.0 mm for selected profiles. Vary thickness gradually, not abruptly.
Inner fillets
Use generous corner radii (≥ 0.5 mm). Sharp internal corners accelerate die wear and cause tearing.
Fin limits
Fin height-to-thickness around 15:1–20:1 practical, up to ~40:1 selected geometry. Beyond that, skive or bond.
Tongue ratio
Avoid slender tongues between slots — high tongue ratio dies are fragile and limit tolerance.
Tolerances
Let extrusion hold the shape; machine only critical faces, holes and threads (EN 755-9 vs ISO 2768).
What you get from the DFM review
The free review is the fastest way to de-risk a new profile.
Deliverables
- Extrudability verdict and suggested changes
- Alloy & temper recommendation (6063 / 6061 / 6082 / 7075)
- Finish and tolerance plan
- Rough tooling cost and lead-time range
- A CAD/STEP draft of the proposed section on request
Questions buyers ask first
On downloads, models and the review.
Do you provide CAD / STEP models?
Yes. We supply STEP files for standard sections and a parametric draft of your custom profile so your team can position it in the assembly before tooling. Request them through the email gate above or with your drawing; the model is built from the same datum we extrude to, so it matches the finished part.
Is the checklist really free?
The design checklist and the DFM review are both free and carry no obligation to order. The checklist is a one-page reference for the five rules that cause most rework; the DFM review is our engineers' read of your drawing with alloy, finish and a price range, returned within 24h on working days.
What do I send for a DFM review?
A CAD/STEP/PDF with critical dimensions, alloy, finish and quantity. We review extrudability, return a DFM report and a rough price, and flag changes that lower cost or lead time. Your drawing stays confidential and NDA is available on request.
Can I get an aluminum profile CAD model before tooling?
Yes — request a STEP through the email gate. For a custom section we build a parametric draft from your envelope so you can verify fit and mounting in the assembly; once tooled, the production model matches the extruded part because both reference the same datum.
