Custom profile development
Custom Aluminum Extrusion Supplier Network
Need a profile that does not exist in any catalog? Submit your drawing or CAD file and connect with custom aluminum extrusion suppliers and manufacturers that can review the design, quote tooling and produce the profile to your specification.
Quoted from your drawing
PDF, DWG, DXF, STEP and STP files can be attached to your request.
Tolerances & alloy specified
Communicate critical dimensions, alloy and temper up front.
From prototype to production
Sample quantities through full production programs on the same tooling.
What a custom aluminum extrusion supplier does
A custom aluminum extrusion supplier produces profiles to a customer's own cross-section rather than a standard catalog shape. The supplier evaluates the design for extrudability, builds the die, extrudes the profile in the specified alloy and temper, and then applies the cutting, machining and finishing steps the part requires.
Custom extrusions replace multi-part fabrications with a single extruded section, hold consistent cross-features along the full length and can integrate functions like cable channels, heat-sink fins, slide tracks or mounting slots directly into the profile. That combination is why engineers specify them in machinery, enclosures, transportation and building systems.
What you can request
- New profile development from an idea, sketch or 3D model
- Reproduction of an existing or legacy profile
- Alloy-specific designs (6063, 6061, 6005A, 6082 and others)
- Hollow and semi-hollow shapes, heat sinks and thin-wall profiles
- Value-added processing: cutting, drilling, CNC machining, bending
- Surface finishing: anodizing, powder coating, polishing
Engineering information that speeds up quoting
- Engineering drawings — dimensioned PDF or 2D CAD (DWG, DXF)
- 3D CAD files — STEP or STP models for volume and tooling review
- Profile dimensions and cross-section geometry
- Alloy requirements and temper (or a request for a recommendation)
- Tolerance requirements, especially on critical-to-quality features
- Surface finish and color — mill, anodized, powder coated or other
- Cutting lengths, end machining, drilling or CNC details
- Reference images or a drawing/reference number for existing profiles
- Application context and any regulatory or documentation needs
Design considerations for custom profiles
Extrusion is a remarkably flexible process, but profiles designed with production in mind cost less and run more consistently. Keep these principles in mind before you finalize a drawing:
- Keep walls uniform. Thick-to-thin transitions cause uneven flow and cooling. Where thick sections are structurally required, discuss ribbing or hollow alternatives.
- Add radii instead of sharp corners. Sharp internal corners concentrate stress and accelerate die wear.
- Respect the circumscribing circle. The bounding circle of your cross-section determines the press size needed — and the achievable tolerance.
- Be deliberate with tolerances. Specify tight tolerances only where function demands them; standard tolerances elsewhere reduce cost.
- Design hollows conservatively. Large hollows need mandrels or bridge dies and affect achievable wall thickness.
Good suppliers will flag manufacturability issues and suggest adjustments — expect that feedback as part of the quoting conversation.
From RFQ to production profile
- Submit the RFQ — drawing, specs, quantity and delivery requirements through the quote form.
- Supplier review — matched suppliers assess extrudability, tooling needs, alloy availability and process route.
- Quote & tooling — responses typically include piece pricing, die/tooling cost and lead times for tooling and first samples.
- Sampling — first articles are produced and measured against the drawing before production release.
- Production & delivery — extrusion, fabrication, finishing and packaging to your delivery schedule.
Frequently asked questions
Can I request custom aluminum extrusions without a finished drawing?
Yes. Many custom projects start from a sketch, a sample or a description of the function. Include dimensions where you have them and explain what the profile must do — matched suppliers can advise on extrusion-friendly geometry before tooling is built. A drawing or CAD file will still be needed before a firm quote and tooling order, so the clearer your input, the faster the process.
What CAD and drawing files can I upload?
You can attach PDF drawings and images (JPG, PNG) as well as CAD and data files — DWG, DXF, STEP, STP and XLSX spreadsheets for schedules or bill-of-materials style data. If your files are large or in another format, describe them in the request notes and the site owner can arrange an alternative transfer.
How is tooling (die) cost handled for custom profiles?
Custom shapes require a die, which is normally quoted as a separate tooling charge or amortized into piece pricing over a committed volume. Tooling cost depends on profile complexity, size and the die type (solid, hollow or bridge). Ask for tooling and sample lead times explicitly in your request so the responses are comparable.
Which alloys are typical for custom extrusions?
6063 is the workhorse alloy for architectural and general-purpose profiles (finishing quality is excellent), while 6061 is preferred where strength matters. 6005/6005A and 6082 serve structural applications, and 6463 suits decorative finishing. If you are unsure, say so in the request — suppliers routinely recommend an alloy-temper combination based on the application.
Can custom extrusions be cut, machined and finished before delivery?
Yes. Value-added processing is a standard part of custom extrusion supply: cut-to-length, drilling and punching, tapping, CNC machining, bending and notching, plus anodizing, powder coating and other surface finishes. List every processing step in the fabrication field of the quote form so suppliers quote the finished part rather than raw profile.
