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.

指出浇道位置的选择首先要保证金属液沿着型壁顺序充填，以减少金属液的流动阻力；内浇道应使液态金属从制件厚壁处开始充填，以利压力的传递，消除缩孔，保证制件的质量。

The electromagnetic pressure produced by the counteract of magnetic field in coil and the eddy current in liquid metal is ma inly determined by the magnetic flux density on the surface and its dissipation in the liquid metal.
