This product is manufactured using high-quality aluminum alloy materials, combined with high-precision CNC milling and professional surface polishing processes. The product features lightweight construction, high strength, stable precision, and a refined appearance, making it widely applicable in consumer electronics, communication equipment, optical instruments, automation machinery, and high-end consumer goods. Through rigorous process design and full-process quality control, the components ensure superior assembly compatibility, structural strength, and visual quality, meeting industry-leading standards.

Production Process Description

The CNC milling process utilizes multi-axis computer numerical control systems to perform three-dimensional machining of aluminum alloy materials, enabling the production of complex curved surfaces, precise grooves, holes, and high-precision assembly interfaces. After machining, the parts undergo a combined manual and mechanical polishing process to effectively remove tool marks and burrs, enhancing surface smoothness and gloss consistency. This combined approach balances dimensional accuracy and aesthetic quality, making it particularly suitable for applications with high demands for both appearance and structure.

Material and Performance Characteristics

Materials such as 6061 and 7075 series aluminum alloys are selected for their excellent strength-to-weight ratio, thermal conductivity, and corrosion resistance. After heat treatment, the mechanical properties are further enhanced, ensuring sufficient load-bearing capacity and durability while reducing weight. The polished surface achieves a uniform and refined texture, providing an excellent base for further surface treatments such as anodizing or sandblasting.

Technical Specifications

Application Industry Examples

Suitable for fields requiring both lightweight design and structural strength: mid-frames, brackets, and internal structural components for consumer electronics; heat dissipation housings and shielding covers for communication equipment; lens barrels and adjustment mounts for optical instruments; fixtures, guide rails, and protective components in industrial automation; and high-end consumer goods such as audio panels and decorative parts.

Quality Control

A full-chain control system is implemented, covering material certification, process inspection, and finished product testing. During machining, online measurement and first-article inspection systems ensure batch consistency. Finished products are verified for dimensions using 3D scanning, projectors, and other inspection methods. Surface quality is assessed through visual inspection under standardized lighting and quantified using roughness testers. All products are accompanied by inspection reports, with key dimensions providing measured data.

Customization Services

Supports custom manufacturing based on customer-provided 2D drawings or 3D models. Process selection, structural optimization, and post-treatment solutions can be recommended based on assembly requirements, usage environment, and appearance standards. The capability includes rapid prototyping and mass production with quick response times. Tailored solutions are also available for special performance requirements, such as conductivity, electromagnetic shielding, or lightweight design.

Packaging and Delivery

Products are packaged in layers with anti-scratch isolation materials, and critical surfaces are protected with adhesive film. Custom packaging solutions, such as vacuum-formed trays, EPE foam padding, or specialized containers, are designed based on product structure and delivery volume to ensure transportation safety. Just-in-time delivery services are provided, with batch shipments arranged to meet customer supply chain requirements.

By combining precision milling and fine polishing, this product achieves a harmonious balance of functionality and aesthetics in aluminum alloy parts, offering customers a high-reliability, high-quality lightweight metal component solution.
