In the production process of Die-Cast Aluminum Accessories, to ensure that the products can achieve high precision and one-time molding of complex structures, it is necessary to comprehensively consider multiple aspects such as design, material selection, mold manufacturing, die-casting process and quality control.1. Precision design and simulation analysis:3D modeling and simulation: In the product design stage, CAD/CAM software is used for 3D modeling, and CAE software (such as finite element analysis software) is used to simulate and analyze the die-casting process to predict possible defects such as pores, shrinkage holes, warping, etc., and determine the best gate and exhaust design position.Optimization design: Through the simulation analysis results, optimize the product design to minimize the impact of complex structures on molding accuracy, such as adding reinforcing ribs, rationalizing the distribution of product wall thickness, etc., to improve the cavity filling speed and uniformity.2. Selection and processing of high-quality materials:Quality control of aluminum ingots: Select high-quality aluminum ingots with high purity and stable chemical composition to avoid the impact of impurities and harmful elements on molding accuracy.Material pretreatment: Preheat the aluminum ingot to achieve the optimal die-casting temperature, improve fluidity, and reduce the thermal shock of the mold.3. High-precision mold manufacturing:High-precision machining: The mold manufacturing process should use a high-precision CNC machining center to ensure the dimensional accuracy and surface quality of the mold and reduce the molding accuracy problems caused by mold defects.Heat treatment: Proper heat treatment of the mold to improve its hardness and wear resistance and extend its service life.Mold material: Select high-quality mold materials suitable for the die-casting process, such as H13 tool steel, to ensure high temperature resistance, wear resistance and high strength.4. Advanced die-casting equipment and process control:High-speed and high-pressure die-casting machine: Select a die-casting machine with high speed and high pressure to ensure that the aluminum alloy liquid fills the mold quickly and evenly, reducing shrinkage and temperature difference during the filling process.Temperature control: Strictly control the temperature during smelting and die-casting, including aluminum liquid temperature, mold temperature and cooling system temperature, to ensure the consistency of casting quality and molding accuracy.Automated control: Apply automated control systems and real-time monitoring instruments to accurately control parameters such as temperature, pressure, speed, and time during the die-casting process to ensure the consistency and accuracy of each die-casting.5. Quality control and testing:Process monitoring: During the die-casting process, use sensors and data acquisition systems to monitor key process parameters in real time to detect and correct deviations in a timely manner.Product testing: Set up online testing equipment on the production line, such as photoelectric sensors, X-ray detectors, etc., to perform real-time testing of key dimensions and defects to ensure that the product is qualified at one time.First piece inspection and sampling inspection: Establish a strict quality control procedure, including regular sampling inspection of first pieces and continuously produced products to ensure that product quality meets design requirements.6. Mold maintenance and care:Regular maintenance: Regularly inspect and maintain the mold, clean the oxide layer and dirt on the mold surface, and keep the mold clean and accurate.Mold treatment: Perform appropriate surface treatment on the mold, such as spraying high-temperature lubricants or hard chrome plating, to reduce mold wear and improve demolding performance.Through the above methods, it is possible to effectively ensure that Die-Cast Aluminum Accessories meet high precision requirements and achieve one-time molding of complex structures. This requires comprehensive management and refined control of the entire process of design, materials, equipment, process and quality control to improve production efficiency and product quality.
