Aluminium extrusion in China — custom profiles without the custom-profile pain
A custom aluminium profile turns machining waste into near-net shape — and extrusion dies are cheap compared with almost any other tooling. P&A International manages extrusion programs through vetted partner plants in China: die design and trial, extrusion in 6063/6061 and architectural alloys, then cutting, machining, anodising and fabrication to finished parts.
One dedicated engineer reviews your profile for extrudability — wall balance, tongue ratios, screw bosses — before the die is cut, and owns quality from billet to boxed parts.

Extrusion services
Custom profiles
Solid, hollow and semi-hollow profiles to your section — dies typically from ~USD 800 and 2-3 weeks.
Extrusion & temper
6063, 6061 and architectural alloys; T5/T6 tempers; mill, anodise-quality and powder-coat surfaces.
Machining extrusions
Cut-to-length, drilled, tapped and CNC-machined features — profiles become finished components.
Anodise & finish
Clear, black and colour anodising, brushing, powder coat — with finish samples approved before production.
Heatsink profiles are a speciality — see the dedicated heatsink page for thermal work.

Why engineers & buyers choose PA
For design engineers
Profiles fail at the die: unbalanced walls tear, sharp tongues wash out, and a section designed without extrusion knowledge costs you in scrap forever. Your engineer fixes the section on paper — usually in one review cycle — before any die steel is cut.
For purchasing
Low die costs make switching easy and quality the differentiator: partner plants vetted to ISO 9000 or better, finish samples signed off before volume, itemised pricing per operation, and one engineer who answers for the whole chain from billet to box.
3 easy steps to get started
Send the section
DXF/STEP of the profile, or the part it replaces — plus lengths, alloy and volumes.
Extrudability review + quote
Section feedback, die cost, per-metre and per-part pricing, finish options.
Die trial to delivery
First articles measured, finish samples approved, then production cut, machined and finished.
Applications
Enclosure bodies and rails, heatsink profiles, solar and battery mounting systems, LED housings, conveyor and framing systems, architectural sections and marine trim — extruded, machined, finished and delivered as components ready for assembly.

Extrusion or another aluminium route?
Constant cross-section changes everything — quick orientation:
| Extrusion | Constant cross-section parts — lowest tooling cost, near-net material use |
| Extrusion + CNC | Profiles needing holes, pockets and milled ends — still cheaper than billet |
| Die casting | Complex 3D geometry at volume — see aluminum die casting |
| CNC from billet | Low volumes or geometry no profile can carry |
What to send us for a fast, accurate quote
The more of this you can share, the quicker we can return a proposed profile and production plan and price:
- Profile drawing (DXF ideal) or the part to convert
- Alloy and temper, or the duty so we can propose
- Cut lengths and tolerance; machining operations needed
- Finish: anodise colour, brush, powder coat RAL
- Annual volume and call-off pattern
Converting a machined or folded part to a profile often halves its cost — send the part and ask.
