充填

It is proposed that the runner location should be first to be selected to ensure molten metal filling along the die wall in order to reduce melt flow resistance and then ingate should be located in the heavy section of the workpiece to which the melt would be filled at the beginning. As a result, the applied pressure could be transmitted fluently to avoid shrinkage cavity and to ensure castings quality.
