When manufacturing Battery Lead Die Casting Parts, how to optimize the die-casting process to improve the mechanical properties and electrical conductivity of the product?

As a professional Battery Lead Die Casting Parts manufacturer, we understand the key role of the die-casting process in ensuring the mechanical properties and electrical conductivity of the product. Optimizing the die-casting process not only improves product quality, but also enhances product performance and reliability in real-world applications. We start from the following aspects to comprehensively optimize the die-casting process to ensure that the mechanical properties and electrical conductivity of the product are optimal:

In the selection of die-casting materials, we use high-purity lead alloys and optimize the alloy composition according to specific application requirements. High-purity lead has excellent electrical conductivity and low melting point, making it suitable for die-casting. In addition, the mechanical properties and corrosion resistance of lead alloys can be further improved by adding appropriate amounts of alloying elements such as antimony, tin and calcium. For example, antimony can significantly increase the strength and hardness of lead alloys, while tin and calcium can improve its toughness and fatigue resistance. These improved alloy compositions significantly improve the mechanical properties of lead die castings while ensuring electrical conductivity.

During the mold design and manufacturing process, we use advanced computer-aided design (CAD) and computer-aided engineering (CAE) technology to accurately design the mold geometry and gating system. By simulating the metal flow and heat conduction behavior during the casting process, we are able to optimize the mold design, reduce pores and shrinkage cavities inside the casting, and ensure the density and uniformity of the casting. High-quality molds not only improve the dimensional accuracy of castings, but also enhance their mechanical properties and electrical conductivity.

During the actual die-casting process, we strictly control process parameters such as the melting temperature of the lead alloy, injection speed, mold temperature and cooling rate. First, by precisely controlling the melting temperature of the lead alloy, the metal melt is ensured to have good fluidity and can fill every detail of the mold, thereby forming a dense, defect-free casting. Secondly, proper adjustment of injection speed and mold temperature can effectively reduce pores and cracks inside the casting and further improve the mechanical properties and electrical conductivity of the casting. In addition, by optimizing the cooling rate, we can control the solidification process of the casting, reduce internal stress and deformation, and ensure the dimensional stability and mechanical strength of the casting.

In order to further improve the performance of lead die castings, we also use a variety of post-processing processes. For example, through the heat treatment process, the residual stress inside the casting can be eliminated and its mechanical properties and service life can be improved. Plating and coating treatments can enhance the corrosion resistance and surface hardness of lead die castings, ensuring their long-term reliability in harsh environments. In addition, we perform machining and precision machining to improve the surface finish and dimensional accuracy of the castings, thereby improving their conductivity and connection reliability.

In terms of environmental protection and safety, how to optimize the production process of Battery Lead Die Casting Parts to reduce the impact on the environment and workers' health?

As a professional Battery Lead Die Casting Parts manufacturer, we know that we must pay attention to environmental protection and safety issues during the production process. Lead is a toxic metal that is potentially harmful to the environment and worker health. Therefore, optimizing the production process to reduce the impact on the environment and worker health is the focus of our continuous attention and improvement. In the selection and processing of raw materials, we strictly control the purity and alloy composition of lead to avoid using raw materials containing harmful impurities. By purchasing high-quality lead ingots and conducting strict quality inspections before entering the factory, we ensure that all raw materials meet environmental protection standards. In addition, we take protective measures during the storage and transportation of raw materials, such as the use of airtight containers and dedicated warehouses, to prevent the leakage of lead dust and vapor.

During the production process, we use advanced melting and die-casting equipment, equipped with efficient flue gas purification systems and dust collection devices. The flue gas and dust generated during the smelting process are filtered and processed through the purification system to ensure that the emissions comply with environmental standards. In order to reduce the generation of lead vapor during the smelting process, we optimized the smelting process parameters, such as controlling the melting temperature and reducing overheating. In addition, we use a closed die-casting machine to reduce the escape of lead vapor and dust and protect the working environment of workers.

During the die-casting process, we use automation and mechanization to reduce workers' direct exposure to lead. We use automatic feeding systems and robotic arms to transport materials and remove castings to avoid manual operations by workers in high temperature and lead vapor environments. The operation and maintenance of the die-casting machine are carried out by professionals who have undergone strict training and are familiar with safe operating procedures and emergency measures to ensure the safety of the production process.

We have also implemented a series of factory environmental control measures to reduce the impact of lead on the environment and worker health. For example, install a high-efficiency ventilation system in the production workshop to keep the air circulated and clean and prevent the accumulation of lead vapor and dust. In addition, production equipment and ventilation systems are regularly maintained and inspected to ensure their normal operation and efficient filtration. For lead waste and residue, we use special equipment to collect and process it to avoid secondary pollution.
