Sino Die Casting, a prominent die casting factory established in 2008 and located in Shenzhen, China, has established itself as a leader in mold making, offering high-precision, durable molds that form the backbone of efficient and high-quality die casting processes. As a high-tech enterprise integrating design, processing, and production, we bring a wealth of expertise and advanced technology to every mold making project, serving clients across industries such as automotive, new energy, robotics, and telecommunications, with our products reaching over 50 countries and regions worldwide. Mold making is a critical step in the die casting process, as the quality of the mold directly impacts the quality, precision, and consistency of the die cast parts. At Sino Die Casting, we recognize this importance and have developed a comprehensive mold making process that combines cutting-edge technology, skilled craftsmanship, and strict quality control to deliver molds that meet the most demanding requirements. Our mold making process begins with a thorough analysis of the client’s part design and specifications. Our team of experienced engineers reviews the 3D models and 2D drawings of the part, assessing factors such as part geometry, material selection, production volume, and surface finish requirements. This analysis helps us determine the optimal mold design, including the number of cavities, gating system, cooling channels, and ejection mechanism, to ensure efficient production and high-quality parts. We collaborate closely with clients during this stage, providing feedback and suggestions to optimize the part design for mold making and die casting, which can reduce costs and improve production efficiency. Once the mold design is finalized, we move to the material selection phase. We use high-quality tool steels, such as H13, P20, and S50C, for mold making, as these materials offer excellent hardness, wear resistance, and thermal conductivity, ensuring that the molds can withstand the high temperatures and pressures of the die casting process and have a long service life. The choice of material depends on factors such as the type of metal being cast, production volume, and the complexity of the part. For high-volume production runs, we often select harder, more wear-resistant steels to ensure the mold can maintain its precision over thousands or millions of cycles. The actual mold making process at our die casting factory involves a range of advanced machining operations, performed with state-of-the-art equipment to achieve exceptional precision. We use CNC milling machines with high-speed spindles and multi-axis capabilities to machine the mold cavities and cores, achieving tight tolerances and smooth surface finishes. Electrical Discharge Machining (EDM) is used for complex geometries and tight corners that are difficult to reach with conventional milling, allowing us to create intricate details with high accuracy. Wire EDM is employed for cutting precise shapes and contours, ensuring that the mold components fit together perfectly. Additionally, we use grinding machines to achieve flatness and parallelism in mold plates, further enhancing the precision of the final mold. Throughout the mold making process, we implement rigorous quality control measures to ensure that each component meets the design specifications. Our quality control team uses precision measuring instruments, such as coordinate measuring machines (CMMs), height gauges, and surface roughness testers, to inspect critical dimensions and surface finishes at every stage of production. This proactive approach to quality ensures that any deviations from the specifications are identified and corrected early, preventing costly rework later in the process. After the individual mold components are machined, we proceed to assembly. Skilled technicians carefully fit together the cavity, core, mold plates, guide pins, bushings, and other components, ensuring that all parts align correctly and move smoothly. The assembly process also includes the installation of cooling channels, which are essential for regulating the temperature of the mold during die casting, ensuring consistent part quality and reducing cycle times. We test the assembled mold to verify that the ejection mechanism works properly, the gating system distributes the molten metal evenly, and the cooling system functions as designed. Once the mold is assembled and tested, we perform a trial run to validate its performance. During this trial, we produce a small batch of parts using the new mold and inspect them for dimensional accuracy, surface quality, and overall integrity. Any issues identified during the trial run are addressed promptly, with adjustments made to the mold as needed. This trial run gives clients the opportunity to review the parts and provide feedback, ensuring that the mold meets their expectations before full-scale production begins. As a die casting factory with ISO 9001 certification, our mold making processes are governed by strict quality management standards, ensuring consistency, reliability, and continuous improvement. We document every step of the mold making process, from design to delivery, providing clients with traceability and transparency. Our commitment to quality has earned us the trust of clients worldwide, who rely on our molds for their critical die casting projects. We also offer mold maintenance and repair services to extend the life of our molds and ensure their continued performance. Regular maintenance, including cleaning, lubrication, and inspection, can prevent premature wear and damage, while timely repairs can address issues such as cracks, wear, or damage to the cavity or core. Our team of experienced technicians can perform these services efficiently, minimizing downtime and keeping our clients’ production lines running smoothly. Whether you need a simple single-cavity mold for a small production run or a complex multi-cavity mold for high-volume manufacturing, Sino Die Casting has the expertise and capabilities to deliver. Our integrated approach to mold making, combined with our commitment to quality and customer satisfaction, makes us the ideal partner for all your mold making needs.
