CFD를 활용한 샷슬리브 최적공정조건 설계 = Optimization of Shot Sleeve Process Conditions Using Computational Fluid Dynamics in Die Casting

다국어 초록 (Multilingual Abstract)

This study aims to optimize the process conditions of the shot sleeve during cold chamber high-pressure die casting to minimize porosity defects, one of the most common quality issues affecting die casting. The movement distance and velocity of the plunger, which are critical parameters in the shot sleeve process, were analyzed to evaluate their effect on air entrapment within the molten metal. Using the commercial casting simulation software Z-Cast Pro, a CFD-based analysis was conducted to determine the optimal slow shot distance and velocity, thereby preventing the formation of air pockets. In addition, ingate velocities during the fast shot phase were analyzed to ensure proper filling while also avoiding mold damage or defects. The results provide a practical process design guideline for improving the casting quality through the CFD-based optimization of shot sleeve parameters in high-pressure die casting.
