As the core component of lighting products, the manufacturing process of lamp housings directly affects product performance, lifespan, and user experience. This article will conduct an in - depth analysis of the key links in lamp housing manufacturing, covering material selection, precision processing, and technological innovation, providing a systematic guide for industry practitioners and those with relevant needs.

 

Core Stage 1: Precise Design and Requirement Analysis

The manufacturing of lamp housings begins with market - oriented design planning. Through requirement research, product functions, appearance styles, and dimensional parameters are clarified. For example, outdoor lamps need to focus on waterproof performance, while decorative lamps emphasize artistic forms. In terms of design tool application, 3D modeling software can generate high - precision drawings and simultaneously optimize structural adaptability to achieve the integration of aesthetics and functionality.

 

Core Stage 2: Material Selection Strategy Driven by Materials Science

Material selection needs to comprehensively consider performance, cost, and environmental protection requirements:

- Metal Materials: Aluminum alloy, with its advantages of light weight and heat conduction, is widely used in LED lamps with high heat dissipation requirements; stainless steel, due to its corrosion resistance, is the first choice for outdoor scenarios.

- Polymer Materials: Engineering plastics such as ABS and PC have insulation properties and injection - molding flexibility, making them suitable for complex curved surface shapes.

- Emerging Materials: The application cases of bamboo - wood composite materials have increased by 32%, meeting the natural aesthetic needs under the trend of low - carbon consumption.

 

Core Stage 3: High - efficiency Molding and Precision Processing Technologies

1. Mold Development: Precision molds are the foundation for large - scale production. Digital simulation technology can shorten the mold debugging cycle by 30%.

2. Innovation in Molding Processes:

   - High - pressure die - casting and CNC fine carving are used for metal housings to ensure the strength of thin - wall structures.

   - Double - color injection molding is used for plastic parts to achieve the integration of texture and light - transmission functions.

3. Post - processing: Laser cutting and automated polishing technologies improve the processing accuracy to ±0.05mm.

 

Core Stage 4: Surface Treatment to Enhance Product Value

- Protection Treatment: The anodic oxidation film of aluminum alloy can reach 15μm, improving weather resistance; the UV spraying curing time of plastic housings is shortened by 40%.

- Decoration Processes: Gradient - color electroplating and IML in - mold transfer printing technologies significantly increase the product's premium space.

 

Core Stage 5: Intelligent Assembly and Quality Control

The fully automatic assembly line is integrated with a visual inspection system, which can identify assembly deviations at the 0.2mm level. Functional tests cover 20 indicators such as IP protection level verification and aging tests to ensure compliance with international safety regulations and certifications.

 

Sustainable Development and Technological Outlook

The industry is accelerating the application of recycled aluminum and bio - based plastics. The penetration rate of 3D printing technology in the small - batch customization field has exceeded 18%. The combination of automated production lines and AI quality control systems keeps the non - defective rate stable above 99.2%.

 

Through systematic optimization of materials, processes, and inspection procedures, modern lamp housing manufacturing has achieved a transformation from traditional processing to intelligent manufacturing, continuously providing high - reliability and high - value - added core components for the lighting industry.
