Core Product: Magnesium Alloy Electronic Lock Die Casting Parts
Our magnesium alloy electronic lock die casting parts strictly follow the core formula of "Product Name + Core Function + Technical Advantage + Application Scenario + Quality Assurance". As critical components for electronic lock operation, these parts mainly include lock body housings, lock core brackets, password panel bases, and deadbolt components. Their core functions are to provide reliable physical protection for internal electronic components (such as circuit boards and sensors), ensure precise assembly of mechanical and electronic structures, and reduce the overall weight of the lock body for easy installation.
Leveraging 10+ years of magnesium alloy casting experience, our parts fully exploit the material's unique advantages: 35% lighter than aluminum alloy counterparts, which simplifies on-site installation of electronic locks; tensile strength up to 250MPa, ensuring resistance to prying and impact; excellent electromagnetic shielding performance, protecting internal electronic components from external interference; and good thermal conductivity, effectively dissipating heat generated by long-term operation of electronic components. These parts are widely applicable to smart home locks, commercial access control locks, industrial security locks, and automotive electronic locks, all complying with international standards such as ASTM, ISO, and CE, and backed by strict quality assurance.
Detailed Production Process of Magnesium Alloy Electronic Lock Die Casting Parts
To ensure the precision and safety performance of electronic lock parts (which require strict dimensional accuracy for electronic-mechanical matching), we adopt a standardized and visualized production process with 8 key steps, implementing strict quality control at each stage. Magnesium alloy die casting is the core process, supplemented by other supporting processes to meet the comprehensive production needs of electronic lock components:
1. Core Process: Magnesium Alloy Die Casting (Detailed Steps)
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 of raw materials, detecting chemical composition and impurity content (ensuring impurity content ≤ 0.005%) to eliminate inferior materials that may affect product strength and durability.
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 and combustion of magnesium alloy. During the melting process, we use rotary degassing technology to remove gas bubbles and impurities in the molten metal, ensuring the cleanliness and fluidity of the molten metal—critical for forming thin-walled electronic lock components.
Mold Design & Preheating: According to the structural characteristics of electronic lock parts (thin walls, complex cavities, and precise hole positions), design high-precision molds using CAD/CAM 3D modeling technology. Before casting, preheat the mold to 180-220℃ to avoid cold shut and misrun defects caused by excessive temperature difference between the molten metal and the mold, and ensure uniform filling of the mold cavity.
Precision 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—parameters optimized for electronic lock parts to ensure full filling of thin-walled structures and precise formation of key holes. The casting cycle is precisely controlled between 20-35 seconds according to the part size, ensuring production efficiency and consistency.
Demolding & Trimming: After the molten metal solidifies (10-15 seconds), the mold is opened automatically to take out the casting. Use CNC trimming machines and high-precision grinding tools to remove gates, runners, burrs, and flash on the casting, especially focusing on the precision of assembly surfaces and hole positions to ensure initial dimensional accuracy.
Heat Treatment: Perform T6 heat treatment on the casting to enhance mechanical properties—solution treatment at 415℃ for 4 hours, followed by water quenching, and artificial aging at 168℃ for 8 hours. This treatment improves the tensile strength and hardness of the part, making it resistant to prying and impact, which is critical for electronic lock security.
2. Supporting Production Processes
Precision Machining: Use 20+ sets of high-precision CNC machining centers to process key surfaces and holes (such as sensor mounting holes, bolt guide holes) with dimensional tolerance controlled within ±0.02mm, ensuring perfect matching with electronic components and mechanical structures.
Surface Treatment: Implement customized surface treatment according to the use environment of electronic locks—common processes include anodizing (for corrosion resistance), powder coating (for scratch resistance and aesthetics), and chemical conversion coating (for electromagnetic shielding enhancement), all meeting environmental protection standards.
Assembly & Performance Testing: Provide assembly services for electronic lock component sets. Conduct comprehensive performance testing, including dimensional inspection (3D coordinate measuring machine), tensile testing, impact testing, corrosion resistance testing (salt spray test), and electromagnetic shielding testing, to ensure product qualification.
