Small-section extrusion
Small cross-section aluminum profiles for compact designs. Send the section drawing, alloy, wall thickness and required length for a feasibility review.
Products · 09
Electronic enclosure profiles
One-piece extruded housings machined for ports, cut-outs and end plates — ready for the boards to slide in.
Start with the profile. Add the processing you need.
Order aluminum profiles and combine the operations your application requires in the same quotation.
Small-batch color anodizing
Blue, red, yellow, green, purple and black color options for small-batch projects. Specify the quantity per color and provide a color sample or reference.
Processing to your drawing
Cutting, hole milling, drilling, welding and stretch bending can be quoted with your profiles. Include hole positions, bend geometry and assembly requirements.
Minimum section size, wall thickness, batch quantity and processing feasibility are confirmed from your drawing. Anodized shades depend on alloy, surface condition and sample approval; white finishes require confirmation of the finishing process.
For your quotation: section drawing · quantity by profile and color · cut lengths · machining or bending drawing · finish reference.
01Have these ready
Six things that turn a slow quote into a fast one.
01

04Three confirmations before production
01
Can we make it?
Section, wall and any fine features are read against the press — small-section capability included.
02
Machining & finish agreed
End machining, cut-outs, ports and the anodize or mill surface are all itemised in the quote.
03
Proof before shipping
Cavity dimensions are gauged so the boards fit, with material or finish certificates as required.
Machining and surface treatment are coordinated according to project requirements — CNC & machining · Finishing.
05Quality & certification
Heat and lot numbers follow every batch
Dimensional reports measured against the signed drawing
Coating-thickness and salt-spray checks on finished surfaces

06Frequently asked questions
Why choose an extruded housing over sheet metal or plastic?
One seamless body, board guides formed into the metal, stiffness, heat spreading and EMI shielding for free — that combination is hard to fold or mould. Where the device runs cool and unshielded, sheet or plastic may still win on cost; describe yours and the comparison comes back honest.
Ports, cut-outs and end plates — who machines those?
We do, in the same building where the profile was extruded. Openings marked on the drawing come back machined, and the anodize is sequenced around them, so the enclosure ships assembly-ready.
How compact can the section be?
This category leans directly on our small-section expertise — down to a 2 mm circumscribing circle and 0.3 mm walls on suitable geometry. If your housing is tight, that is a reason to talk to us, not a problem.
Can the enclosure be made weatherproof?
Ingress protection is a system property — gasket, end caps and joints together, not the extrusion alone. Name the rating you need and we confirm the grooves and cap fits the profile must carry to reach it.
