Custom Extrusion & Capabilities

Custom aluminum profiles, from drawing review and tooling to extrusion, surface finishing and secondary fabrication. Our Foshan factory operates seven extrusion lines and two powder-coating lines, supported by specialist partners for selected processes.

01 / Process & scope

Manufacturing at a glance.

01 / Process overview

Custom Extrusion

Develop your profile from a CAD drawing, 3D model or physical sample, with an engineering review before quotation.
We confirm the cross-section, alloy, finish and quantity, then assess the minimum order weight for each profile and color.

02 / Process overview

Die Development

Select an existing die or develop custom tooling through specialist die makers and in-house extrusion trials.
Each tooling project follows written drawing approval, agreed die fees and sample acceptance requirements.

03 / Process overview

Aluminum Extrusion

Seven extrusion lines with presses rated from 800 to 1,500 metric tons support architectural and industrial profile production.
6063 and 6061 are available, with 6005 and 6082 reviewed for each project. Profile geometry and temper determine the production limits.

04 / Process overview

Surface Finishing

In-house powder coating and wood-grain transfer, plus anodizing and electrophoretic coating through specialist partners.
The finish, color, film thickness and visible surfaces are agreed and documented, with a retained master sample as the reference.
Explore surface finishing
05 / Process overview

Secondary Fabrication

Cut-to-length sawing and standard punching in-house, with drilling, tapping, CNC machining and other operations coordinated through specialist partners.
We supply full lengths, cut profiles or finished parts, with machining tolerances confirmed against the approved drawing.

06 / Process overview

Quality Control

Incoming material inspection, signed first-piece approval, in-process inspections and final inspection before shipment.
Batch records link inspection results to production records and billet heat numbers. Reports are available with the shipment.

02 / Technical specifications

Key production specifications.

Alloys & tempers
6063: T5 / T6. 6061: T4 / T5 / T6. 6005 and 6082: T5 / T6, subject to alloy-specific order minimums and engineering review.
Profile dimensions & tolerances
Typical wall thickness: 0.8–15.0 mm. Standard delivery length: 3,000–6,000 mm. Cross-section dimensions, thin walls and extended lengths are assessed together.
Surface finishing
Powder coating and wood-grain transfer: up to 6,500 mm. Anodizing and electrophoretic coating through specialist partners: up to 6,000 mm. Section geometry and fixturing are also reviewed.
Secondary fabrication
Cut lengths: 20–6,000 mm, with a typical cutting tolerance of ±0.5 mm. Hole and CNC tolerances depend on the operation and approved drawing.
Inspection & records
Inspection covers dimensions, wall thickness, hardness, film thickness, color and appearance, with first-piece approval and in-process checks every 1–2 hours.
