With over 10 years of focused expertise in magnesium alloy casting components, we are a professional integrated manufacturer and foreign trade enterprise, specializing in high-precision magnesium alloy projector light source housing and customized magnesium alloy casting products. Our profound mastery of magnesium alloy material properties and precision casting technology enables us to deliver housings that excel in efficient heat dissipation, lightweight performance, and structural stability—core advantages tailored to the rigorous requirements of projector light source systems (where heat control directly affects light efficiency and service life). We have established long-term cooperative relationships with global projector manufacturers, integrating mature production capabilities with professional foreign trade services to ensure seamless cooperation from technical docking to global delivery.
Core Product: Magnesium Alloy Projector Light Source Housing
Our magnesium alloy projector light source housing strictly follows the core formula of "Product Name + Core Function + Technical Advantage + Application Scenario + Quality Assurance". As a critical component of the projector's light source system, its core functions are to provide reliable protection for high-temperature light source components (such as bulbs and LEDs), achieve rapid heat conduction and dissipation, and ensure precise assembly with optical components and the projector main body.
Leveraging 10+ years of magnesium alloy casting experience, our housings fully exploit the material's unique advantages: thermal conductivity up to 156 W/(m·K), which is 30% higher than aluminum alloy, effectively reducing the temperature of the light source and extending its service life by 20%+; 35% lighter than aluminum alloy counterparts, contributing to the overall lightweight design of projectors; and excellent structural rigidity, ensuring no deformation under long-term high-temperature operation. These housings are widely applicable to home projectors, commercial education projectors, engineering laser projectors, and portable projectors, all complying with international standards such as ASTM, ISO, and RoHS, and backed by strict quality assurance.
Production Process of Magnesium Alloy Projector Light Source Housing
To ensure the heat dissipation performance and precision of the light source housing (critical for matching optical components), we adopt a standardized and visualized production process, with magnesium alloy precision die casting as the core, supplemented by other supporting processes to meet comprehensive production needs:
1. Core Process: Magnesium Alloy Precision Die Casting
Raw Material Inspection & Preparation: Select high-purity magnesium alloy ingots (AZ91D, AM60B, ZK60A, etc.) that meet ASTM B94 standards. Use advanced spectral analysis equipment to conduct 100% incoming inspection, detecting chemical composition and impurity content (ensuring impurity content ≤ 0.005%) to avoid affecting thermal conductivity and mechanical properties.
Magnesium Alloy Melting: Put qualified ingots into a professional resistance melting furnace, heating to 650-700℃ under the protection of SF6+CO2 mixed gas to prevent oxidation. During melting, rotary degassing technology is used to remove gas bubbles and impurities, ensuring the cleanliness and fluidity of molten metal—critical for forming the thin-walled and complex cavity structure of the light source housing.
Mold Design & Preheating: Based on the housing's structural characteristics (integrated heat dissipation fins, precise optical component mounting holes), design high-precision molds using CAD/CAM 3D modeling technology. Preheat the mold to 180-220℃ before casting to avoid cold shut defects and ensure uniform filling of the mold cavity, especially for the thin-walled heat dissipation fins.
Die Casting Molding: Adopt cold-chamber die casting technology, injecting molten magnesium alloy into the mold at a pressure of 130-160MPa and a speed of 4-6m/s. These parameters are optimized to ensure full filling of the heat dissipation fins and precise formation of mounting holes. The casting cycle is controlled between 22-38 seconds according to the housing size, balancing efficiency and quality.
Demolding & Trimming: After the molten metal solidifies (11-16 seconds), the mold is opened automatically. Use CNC trimming machines and high-precision grinding tools to remove gates, runners, and burrs, focusing on the flatness of the optical component mounting surface and the integrity of the heat dissipation fins.
Heat Treatment & Stress Relief: Perform T6 heat treatment (solution treatment at 415℃ for 4 hours, water quenching, artificial aging at 168℃ for 8 hours) to enhance mechanical properties. An additional stress relief annealing step is added to avoid deformation under long-term high-temperature operation of the housing.
2. Supporting Production Processes
Precision Machining: Use 20+ sets of high-precision CNC machining centers to process key surfaces and holes (optical component mounting holes, heat sink fixing holes) with dimensional tolerance controlled within ±0.02mm, ensuring perfect matching with optical and electronic components.
Surface Treatment: Implement customized surface treatment to enhance heat dissipation and corrosion resistance, including anodizing (improves heat dissipation efficiency), chemical conversion coating (anti-corrosion), and high-temperature resistant powder coating (for harsh environment applications), all meeting environmental protection standards.
Performance Testing: Conduct comprehensive testing, including dimensional inspection (3D coordinate measuring machine), thermal conductivity testing, high-temperature resistance testing (120℃ continuous operation for 1000 hours), and corrosion resistance testing (salt spray test), to ensure product qualification.
