OEM Aluminium Extrusion Profiles – Custom Manufacturing | Shengxin

OEM Aluminium Extrusion Profiles are built for companies that sell window and door systems under their own brand. You provide the drawings — or work with our engineers to develop them — and we manufacture the profiles to your exact specification, with your branding, your tolerances, and your quality standards. Confidentiality is built into the process: your die designs, profile geometries, and production volumes are never shared with other customers. When you buy OEM from Shengxin, you get a manufacturing partner, not a competitor.

The process starts with your requirement. We check our 500,000+ die library first — if a suitable profile already exists, we can modify or use it directly, saving you tooling cost and lead time. If not, our in-house die shop designs and manufactures a new die, then extrudes trial sections for your approval before full production. From there, we handle everything: extrusion, machining, surface finishing, and packaging. The final profiles arrive ready for your fabrication line, or fully machined and finished to your cutting schedule.

Shengxin has over 30 years of aluminium extrusion expertise and operates 35 extrusion lines up to 5,500 tons. For clients who need a complete system, we can coordinate profiles across multiple components — outer frames, sashes, glazing beads, reinforcement — all from the same alloy batch and finish run. For standard thermal break systems, see our thermal break window profile technology. If you need a bespoke section developed, our custom extrusion service is the route to follow.

Features & Benefits

• Complete confidentiality: Your profile designs, die specifications, and production volumes are treated as proprietary information. We sign NDAs before any technical discussion begins.
• 500,000+ die library advantage: Before designing new tooling, we search our extensive inventory. Many OEM requests can be fulfilled using existing dies, saving significant tooling costs and shortening lead times.
• Full in-house production: Extrusion, machining, anodizing, powder coating, and PVDF finishing all happen under one roof. You get a single accountable partner with full traceability from billet to finished profile.
• Scalable from prototype to volume: Start with a few hundred kilos for testing and certification, then scale to multi-ton production on the same extrusion lines without process changes or requalification.
• Your brand, your quality: We manufacture to your drawings and tolerances, not ours. Your quality manual defines the acceptance criteria, and we document every batch to your requirements.
• Dedicated project engineer: Every OEM client is assigned a project engineer who manages the process from design review through delivery, ensuring clear communication and on-time completion.

OEM Project Process

From initial drawing to production delivery, the OEM process follows a transparent, documented path.

Please note: Timelines are typical estimates based on smooth approvals and current scheduling. Actual durations may be longer if design changes are needed, multiple sample iterations are required, or production capacity is at high demand. Your project engineer will provide updated timelines at each stage, and final delivery dates will be confirmed in your order confirmation.

Technical Specifications

As part of our broader aluminum profiles for doors and windows range, we also manufacture slim anodized standard-size cabinet door aluminum profile sections for interior applications — ideal for OEM clients who want to coordinate finishes across multiple product lines.

Who Uses OEM Aluminium Extrusion Profiles?

• Window and door system brands: Companies selling under their own brand use OEM profiles to create distinctive, proprietary systems that competitors cannot copy.
• Fabricators seeking product differentiation: For fabricators who want to offer a unique profile that sets them apart in a crowded market, OEM production provides that edge.
• Architects with bespoke facade designs: When a project calls for a specific sightline or geometry, OEM custom profiles make the architectural vision achievable.
• Importers and distributors: Businesses importing aluminium profiles for their local market rely on OEM manufacturing for consistent quality and reliable supply.
• Developers with private label needs: Property developers with a signature window style commission OEM profiles to maintain design consistency across multiple projects.

OEM Aluminium Extrusion Profiles FAQ

Custom OEM Extrusion Solutions

If your brand requires proprietary window or door profiles, Shengxin's OEM extrusion service can develop and manufacture them to your exact drawings — confidentially, with your branding, and delivered ready for your fabrication line.

How It Works:

1. Sign the NDA — we formalise confidentiality before any technical exchange.
2. Send your drawing — 2D PDF/DWG or 3D STEP/IGES file showing the profile geometry and finish requirements.
3. Our engineers review — we assess extrudability and suggest optimisations for performance and cost.
4. Receive a quotation — including die cost, unit price, and lead time.
5. Approve a sample — we extrude and finish a trial section for your approval before full production.

⚠️ Important Note: All profile images and dimensional drawings on this page are for reference only. Final dimensions, finishes, tolerances, and packaging will be confirmed based on your approved production drawings and confidentiality agreement. Please contact our engineering team to discuss your specific OEM requirements before placing an order.

Please note: The production timelines discussed are typical estimates based on smooth design approvals and current scheduling. Actual lead times may be longer if design changes are required, multiple sample iterations are needed, or production capacity is temporarily at high demand. Your dedicated project engineer will provide updated timelines at each stage, and final delivery dates will be confirmed in your order confirmation.
