In the Semi-Solid Processing of indirect squeeze casting, runners were needed for each part cavity. In our experiment, it was found that some of the runners were blocked, and some parts were not filling in full mold. Numerical simulation was applied to analyze this phenomenon, and the results show that it was the shell which emerged on the chamber surface that blocked the runner. Experimental results also confirmed our interpretation. Some measures have been used to correct it, such as runner design, two-layer coating, and process improvement which eliminated blocking of the runner.
