In recent years, widespread use of advanced ceramics in vast areas of the industries such as medical technology and automotive industries has led to the growth of the advanced ceramics market. Due to the difficult machining processes and the difficulty of forming complex parts, manufacturing of ceramic components has been restricted. Powder injection molding can be used to overcome these restrictions. In this paper, SiC feedstock was injected at various temperatures and flow rates. Numerical and experimental results of injection step and imbalance filling were studied. As well as the separation of powder and binder was simulated and verified by experimental tests. Thermogravimetric analyzer and rotational rheometer were employed to evaluate the separation in the green parts and rheological properties of the prepared feedstocks, respectively.

近年来，先进陶瓷在医疗技术、汽车工业等广泛领域的广泛应用，带动了先进陶瓷市场的增长。由于机械加工工艺难度大，复杂零件成型困难，陶瓷部件的制造一直受到限制。粉末注射成型可用于克服这些限制。在本文中，碳化硅原料在不同的温度和流速下注入。研究了注射步骤和不平衡填充的数值和实验结果。以及通过实验测试模拟和验证粉末和粘合剂的分离。热重分析仪和旋转流变仪分别用于评估生坯分离和制备原料的流变性能。
