About Alusat — Aluminum Extrusion Manufacturer in Dongguan, China
Alusat is an aluminum extrusion manufacturer based in Dongguan, Guangdong, China, supplying custom aluminum profiles and finished aluminum components to global OEM customers across North America, Europe, Asia and beyond. We operate as a single-source manufacturing partner: from the first extrusion die design to the final anodized, inspected and packed component, every operation sits under one roof and one quality system.
For engineering and procurement teams who need more than a raw profile, Alusat delivers custom aluminum profile solutions — extruded shapes engineered around your drawing, tolerance and finish, then fabricated, machined and finished into parts that arrive installation-ready.
As an aluminum extrusion manufacturer in China, Alusat combines Pearl River Delta supply-chain density with export discipline. Buyers get the cost structure and responsiveness associated with southern Chinese manufacturing without surrendering the engineering review, documentation and quality evidence that overseas programs require. Our team works in English and handles drawings, standards and compliance the way US and EU procurement teams expect, so working with a factory in Dongguan feels like working with a local supplier.
Integrated Aluminum Extrusion Manufacturing
Our plant runs a complete extrusion value chain so accountability for quality never leaves the building:
- Die design and tooling — in-house extrusion die engineering, including a design-for-manufacturability review, so wall thickness, tolerances and die lines are resolved before steel is cut.
- Extrusion — aluminum extrusion presses spanning a broad tonnage range, producing solid, hollow, semi-hollow and multi-void profiles in both standard and thin-wall geometries.
- Heat treatment — aging ovens for T4, T5 and T6 tempers to reach the mechanical properties your application demands.
- Cutting and fabrication — precision sawing, drilling, tapping, bending, welding and assembly of extruded profiles into finished sub-assemblies.
- CNC machining — multi-axis CNC machining centers for milling, turning and complex features on aluminum profiles and components to tight tolerances.
- Surface finishing — anodizing (clear and color), powder coating, polishing and brushing for corrosion resistance and appearance.
- Inspection — CMM dimensional inspection, alloy verification and full production traceability on every order.
This vertical integration is what lets us quote realistically, hold lead times and keep tolerances consistent from first prototype to high-volume production.
From Drawing to Delivered Part
A typical custom aluminum extrusion program at Alusat follows a predictable path:
- Feasibility and quoting — you send a drawing, sample or sketch; our engineers review alloy, wall thickness, tolerances and finish, then return a feasibility assessment and quotation.
- Die development — once the program is approved, we design and manufacture the extrusion die, with a design-for-manufacturability check before any steel is cut.
- Extrusion and aging — billets are heated and extruded to the target profile, then aged to the required temper (T4, T5 or T6).
- Cutting and fabrication — profiles are cut to length and, where needed, drilled, tapped, bent, welded or assembled.
- CNC machining — features that cannot be extruded — pockets, threads, precision bores — are produced on CNC machining centers.
- Surface finishing — anodizing, powder coating, polishing or brushing is applied to meet appearance and corrosion requirements.
- Inspection and packing — CMM and dimensional checks confirm conformance, then parts are packed and documented for export.
Because every step is co-located, a design change that would normally bounce between several suppliers is resolved in one conversation.
Extrusion Dies and Tooling
The die determines profile quality, so we invest in it up front. Alusat designs and manufactures solid, hollow and multi-void extrusion dies, choosing single- or multi-cavity layouts based on section size, wall thickness and annual volume. Die features such as bearing length and relief are tuned to control metal flow, reduce die lines and hold tolerances; for thin-wall or complex hollow sections this tuning is the difference between a profitable profile and a scrap-prone one. Standing tooling is stored, maintained and recertified between runs, so repeat orders start from a known-good die rather than a fresh setup.
Custom Aluminum Profiles in the Alloys You Specify
Alusat extrudes the full range of wrought aluminum alloys used in structural, thermal and cosmetic applications:
- 6061 — the general-purpose structural alloy, easy to machine and weld, ideal for frames and brackets.
- 6063 — the architectural and decorative alloy, with excellent anodizing response for visible surfaces.
- 6005A — a higher-strength structural alloy for transport and framing systems.
- 6082 — a strength-optimized alloy for demanding mechanical and structural parts.
- 7075 — the high-strength aerospace-grade alloy for performance-critical components.
Our engineers recommend the right alloy and temper for your load, thermal and cosmetic requirements, verify chemistry and temper before shipment, and document the result for traceability. Common tempers include T5 and T6 for structural parts and T4 where further forming is required after extrusion.
Surface Finishing Options
Alusat offers the finishing routes most specified for aluminum extrusions:
- Anodizing — an electrolytic oxide layer, typically 5–25 µm, in clear, black or bronze. Anodizing improves corrosion and wear resistance and gives a durable, dye-stable appearance; it is the default for visible architectural and consumer surfaces.
- Powder coating — a cured polymer layer, typically 40–80 µm, in standard and custom RAL colors, with strong UV and chemical resistance for outdoor and industrial use.
- Polishing — mechanical or chemical polishing for a bright, reflective finish on decorative parts.
- Brushing — a satin, directional grain for a consistent non-glare surface.
Where a part needs both protection and color, we can combine processes — for example, anodize then dye, or chrome-free pretreat then powder coat — and will advise on the most cost-effective route for your environment and volume.
Tolerances and Manufacturing Capability
Typical aluminum extrusion capabilities at Alusat include:
- Press tonnage — a range of extrusion presses covering small to large profile sections within a single plant.
- Profile geometry — solid, hollow, semi-hollow and multi-void shapes, including thin-wall sections for weight-sensitive designs.
- Cut lengths — standard and custom cut lengths, deburred and packed to your specification.
- Dimensional tolerances — general extrusion tolerances to international standards, with tighter custom limits available where the application requires them.
- Surface finishing — clear and colored anodizing for corrosion resistance and appearance, plus powder coating in standard and custom colors, polishing and brushing.
- Straightness and twist — controlled within standard extrusion limits, with corrective straightening where needed.
If your drawing calls for a tolerance tighter than standard, send it to us — we will tell you early whether it is achievable by extrusion alone or needs secondary CNC machining.
Engineering Support and Design for Manufacturability
Before any tooling is cut, Alusat’s engineers review your drawing for extrudability. We look at wall-thickness consistency, symmetry, die-line risk, tolerance achievability and how the profile will be handled and finished after extrusion. Where a small change in geometry removes a secondary operation or improves yield, we will tell you — because a profile that is cheap to make is cheap to buy.
This engineering-led approach is why many OEM buyers keep Alusat as a long-term extrusion partner rather than a one-off supplier. We treat the drawing as the start of a manufacturing conversation, not a fixed specification, and we share what we know about alloy behavior, die wear and finishing so your part performs in the field.
Built for Global OEM Customers and Export Markets
Alusat supplies OEM manufacturers and brand owners who build products for export markets in the United States, the European Union and across Asia. We are accustomed to international documentation, packing and logistics — from first-article and PPAP-style submission packages to export crating and container consolidation — and we work in metric and imperial drawings alike.
Typical OEM programs include:
- Long-run extruded profiles with annual volume commitments and call-off scheduling.
- Build-to-print aluminum components machined and finished to your specification.
- New-product development support, from prototype extrusions to first-article inspection.
Because tooling, extrusion and finishing are co-located, we iterate quickly when a design changes — a real advantage for teams bringing a new product to market on a fixed timeline.
Sampling, Lead Times and Production Volume
Alusat supports the full program lifecycle:
- Prototypes and samples — first-article extrusions and machined samples for fit, form and function checks before volume commitment.
- Pilot runs — small batches to validate finishing, packing and line integration.
- Volume production — recurring production with call-off scheduling against annual framework agreements.
Lead times depend on die status, alloy and finishing, but because extrusion, fabrication and finishing share one site, we avoid the hand-off delays that multiply when work is split across vendors. For repeat programs with standing tooling, reorder lead times are substantially shorter than for a first article.
Applications Across Industries
Alusat’s extruded aluminum components serve a wide set of industries:
- Automotive & EV — battery tray rails, enclosure sections, roof rails and structural members where mass reduction improves range and efficiency.
- Electronics — amplifier chassis, sensor housings, rack mounts and enclosures with integrated heatsink features.
- Heat sinks — extruded fin stacks for servo drives, power supplies, LED engines and telecom equipment.
- Solar energy — frame sections, rail channels and inverter housings resistant to outdoor corrosion.
- LED lighting — linear housing extrusions, track profiles and downlight rings with built-in thermal paths.
- Architecture — curtain-wall mullions, window and door frames, balustrade rails and decorative trims.
- Industrial automation — T-slot framing, guard enclosures, cable-management channels and linear-motion carriages.
Most custom profiles start as a conversation about function, load and environment — if your application is not listed, send us the drawing.
Aluminum: The Practical, Sustainable Choice
Aluminum is light, corrosion-resistant and fully recyclable, which matters for both product performance and regulatory expectations in export markets. Specifying extruded aluminum lets you reduce component weight without sacrificing strength, and the material can be recycled repeatedly with minimal loss of properties — a point increasingly relevant for EU and North American buyers with sustainability requirements.
Quality Control You Can Audit
Quality is built into the process, not inspected in at the end. Alusat operates under an ISO 9001 quality management system with in-house CMM inspection, alloy verification, dimensional checking and full production traceability. For automotive and EV programs we apply disciplined controls appropriate to the application, and we can support first-article and PPAP-style documentation on request.
