Product Details

Excellent weather resistance and surface treatment:

Aluminum alloy substrate is naturally corrosion-resistant, and the surface can be anodized (commonly used natural color, black, other colors), sandblasted oxidation, spraying and other treatments.

The surface treatment is not only beautiful, but also greatly enhances the wear resistance, corrosion resistance, and UV resistance, extending the service life of the shell.

FAQ

Q: Why choose extrusion + CNC solution instead of die casting?

A: Compared with die casting process, aluminum alloy extrusion profiles have:

Higher material density (no pore defects)

Better thermal conductivity path (continuous grain flow direction)

Lower mold cost (simple section saves 60% mold opening fee)

Cooperate with CNC precision machining to achieve micron-level interface accuracy

Q: How does CNC machining ensure large-scale consistency?

A: Through three core controls:

Standardization of tooling and fixtures (positioning error <0.02mm)

Intelligent management of tool life (automatic compensation system)

Three-dimensional detection of the first piece (CMM full-size report)

Q: Customization cycle and minimum order quantity?

A: Adopting a flexible manufacturing system: 50 pieces minimum order (CNC process dominated)

First order delivery time 15 days (including extrusion die development)

Mass production weekly capacity 10K+ (automated CNC production line)

Q: What are the benefits of surface treatment "anodizing"?

A: Anodizing (especially hard oxidation) can significantly improve the surface of aluminum alloy:

Hardness and wear resistance: resist scratches during installation and use.

Corrosion resistance: form a dense oxide film to resist environmental erosion.

Insulation: The oxide film is a good insulator.

Aesthetics: provide uniform and stable multiple color options.

Q: What is the cycle and cost of customizing such a shell?

A: The cycle and cost depend on complexity, size, and quantity:

Extrusion die development: A one-time die fee is required, and the cycle is about 2-6 weeks (depending on complexity). For standard cross-sections or existing dies that can be reused, it is faster.

CNC programming and processing: The first piece involves programming and debugging time, and subsequent batch production is efficient. The main cost of small batch customization is CNC processing hours and materials.

In general: Extrusion + CNC process has very good cost-effectiveness and flexibility in the production of customized shells with small and medium batches, high precision, and high quality requirements. In large-scale production, the shared mold cost makes the unit price more competitive.
