- Existing mold library: more than 50,000 dies, helping reduce tooling costs and development lead times when a suitable mold is available.
- Custom profile development based on 2D engineering drawings, 3D CAD files, sketches, or reference samples.
- Integrated extrusion, surface treatment, and CNC machining services.
Whether you need a standard industrial extrusion or a complex custom aluminum component, our engineering and production teams can assess your requirements and recommend a suitable manufacturing solution.


Sample Lead Time, Production Time & MOQ
We understand that overseas buyers often need physical samples to verify dimensions, assembly compatibility, surface finish, and product performance before approving mass production.
Our typical production arrangements are:
| Item | Lead Time / Requirement |
|---|---|
| Sample lead time | 7–10 working days after drawing confirmation and mold payment |
| Bulk production lead time | 25–35 working days after deposit receipt |
| Standard MOQ | 500 kg per custom profile |
| MOQ flexibility | Negotiable for long-term or framework orders |
| Sample inspection | Dimensional, hardness, and salt spray testing can be arranged according to project requirements |
Actual lead times depend on profile complexity, mold availability, surface treatment, machining requirements, and order quantity. We confirm the production schedule after reviewing the project specifications.
OEM & ODM Custom Aluminum Profile Manufacturing Process
Our structured OEM and ODM workflow is designed to make every stage clear, from initial drawings to finished products. By combining extrusion and secondary machining in one manufacturing system, we help reduce communication gaps and unnecessary production revisions.
Step 1: Drawing Review & Design for Manufacturability (DFM)
Send us your 2D drawings, 3D CAD files, sketches, or reference samples. Our engineering team reviews the design, checks manufacturing feasibility, and identifies potential improvements to help optimize material usage, tooling, and production costs.
Step 2: Custom Extrusion Die Development
We evaluate whether an existing extrusion die can meet your requirements or whether a new custom mold is needed. Our mold development process is intended to achieve the required profile geometry and dimensional specifications.
Step 3: Trial Extrusion & First Article Inspection (FAI)
We produce trial samples for dimensional verification. First article inspection results and relevant measurements can be provided for your review and approval.
Step 4: Aluminum Surface Treatment
Depending on the application and finish requirements, available surface treatment options include:
- Anodizing
- Powder coating
- Wood grain thermal transfer
- Fluorocarbon coating
- Polishing
- Brushed
- Electrophoresis
Step 5: CNC Secondary Machining & Fabrication
We provide secondary processing services such as cutting, drilling, tapping, milling, and other CNC machining operations according to your drawings.
Step 6: Final Inspection, Packaging & Shipment
Finished products undergo the agreed inspection procedures before protective packaging and shipment arrangements. Inspection records and export documents can be prepared according to project requirements.
Quality Control & Factory Audit Support
Consistent quality is essential when sourcing custom aluminum profiles for construction, industrial equipment, and engineering projects.
Our production and quality management processes are designed to maintain control throughout material selection, extrusion, surface treatment, machining, and final inspection.
Our quality control capabilities include:
- Raw material control: Aluminum ingot composition and material requirements can be checked against applicable GB/T 3190-2020 requirements.
- Surface finish inspection: Anodized products can undergo salt spray testing, including 48-hour testing where specified by the project.
- Dimensional inspection: Profile dimensions and machined features are checked against approved drawings and agreed tolerances.
- Precision machining: Tolerances of up to ±0.03 mm may be achievable for selected features, subject to part geometry, material, machining process, and inspection method.
- Third-party inspection: We welcome qualified third-party factory audits and on-site production inspections.
- Documentation support: Relevant test reports, inspection records, and certificates can be compiled for project documentation.
Our quality management system and available certifications can be discussed during the supplier qualification process. Specific certification documents are provided according to the product, facility, and project requirements.
