| Abstract Scope |
Die casting is a widely-used casting process for manufacturing complex-shaped products, offering cost reduction and improved productivity. However, it faces challenges due to gas-induced defects inherited from the high-speed and pressureed melts injection. This study aims to develop and optimize a die casting process to minimize gas induced porosity defects. Experiments involved die-casting mold analysis, CT analysis of specimens made from ADC12 alloy, and monitoring oxygen concentration in the die cavity. Results indicated that pore distribution in the interlocking part of the test specimens matched with casting analysis. To optimize the die casting process, oxygen injection into the die cavity conditions were made and the die casting were conducted under these conditions. The study provides basic data for optimizing die-casting process with different oxygen concentration environments and lays the groundwork for further research on die-casting using this process. |
