Custom Aluminum Extrusion Services

Our tolerance control follows ISO 9001 certified standards: critical dimension tolerances are stably within ±0.1mm, and regular dimension tolerances are ±0.15mm. Standard tolerances can meet most general scenario needs and effectively control costs; we only recommend stricter tolerance schemes when parts require precise assembly.

We offer steel profile mechanical connection solutions: non-welding fastening via corner brackets, metal screws, or general mechanical connectors, suitable for regular rack requirements. In addition, combinations of mechanical fasteners and structural adhesives can also replace welding; steel profiles have higher strength but slightly higher assembly complexity, while aluminum extrusions still have core advantages in assembly convenience.

Wall thickness determination requires comprehensive practical considerations: • Alloy Grade: Soft alloys need increased wall thickness to ensure strength, while high-strength alloys can adapt to thin-wall designs • Profile Design: Deep channel or curved structures require thicker walls to improve stability • Press Capacity: The tonnage of extrusion equipment limits the forming limit of cross-sections • Surface Finishing: Coating or anodizing may require minimum wall thickness to avoid deformation • Dimensional Tolerance: Tolerance limits usually require increasing wall thickness to ensure processing consistency We will balance strength, weight, and cost during the design phase.

The typical recommended wall thickness is 1.0mm-2.5mm: • Structural or load-bearing parts: Wall thickness ≥2.0mm is recommended to ensure strength and rigidity • Lightweight or decorative parts: Wall thickness ≈1.0mm is sufficient The minimum feasible wall thickness is limited by alloy, cross-section complexity, and equipment capacity; the final choice needs to balance requirements and cost based on the actual scenario.

We provide prototyping and small-batch trial production services, which can produce sample parts for testing and verification before mass production. Prototyping services can help you: • Verify fit and function before committing to large quantities • Confirm that dimensions and tolerances meet requirements • Evaluate surface finishing effects • Optimize design early in development to reduce later risks.

Costs are determined by core factors: • Material Type: Common alloys like 6061/6063 are cheaper than specialty metals • Part Size: Larger profiles require more material and larger equipment, resulting in higher costs • Design Complexity: Complex cross-sections require custom molds, and tight tolerances increase processing time • Other Factors Affecting Price: Order volume (larger orders have lower unit costs), surface finish type, tooling and die costs for new profiles You can provide drawings and requirements, and we will give you an accurate quote.

Cost control can be effectively achieved through design and planning: • Optimize Structural Design: Keep wall thickness uniform, use rounded corners instead of sharp angles, design symmetrically as much as possible, and avoid difficult-to-form deep narrow channels • Choose Standard Materials: Prioritize standard alloys like 6061/6063 to reduce material costs • Plan Orders Reasonably: Increase order volume to spread tooling costs, and only choose tight tolerances when necessary • Simplify Surface Finishing: Prioritize standardized surface processes and consider reusing existing die profiles • Lock Design Early: Changing designs after mold completion will increase costs; we recommend early collaborative planning.

Aluminum extrusions are 100% recyclable without losing performance. The carbon emissions of recycled aluminum are much lower than primary aluminum, meeting environmental requirements; we support recycling systems and can reuse materials multiple times, which is both environmentally friendly and performance-guaranteed.

Core die types include: • Solid Dies: Used for simple solid profiles, with the lowest cost and highest efficiency • Hollow Dies: Used for profiles with hollow sections or tubes, with higher complexity and cost • Semi-Hollow Dies: Used for profiles with partially enclosed sections, with complexity and cost between solid and hollow dies We will match the optimal die solution based on your needs.

We offer a full range of standard T-slot profiles with sizes including: 10×10mm, 20×20mm, 30×30mm, 40×40mm, 45×45mm, 50×50mm, 60×60mm, 80×80mm, 100×100mm, 160×160mm. These sizes are suitable for regular rack and assembly scenarios, and you can select corresponding specifications according to needs.

Lead time depends on the project type: • Prototyping/Small Batch: 5-7 days (including mold development and trial production) • Mass Production: 10-20 days (including mold verification and production) • Regular projects: We can provide a stable delivery schedule to ensure batch supply.

We provide standardized post-processing solutions: • Aging Treatment: Improve alloy strength and hardness, suitable for regular industrial scenarios • Regular Surface Treatment: Achieve a surface finish of Ra≤1.6μm, meeting general needs • General Coating: Increase corrosion resistance, suitable for ordinary working conditions We will match a suitable post-processing process based on your needs.
