In accordance with the phenomenon of the EPS particles’ not being filled into the complex mould fully druing manufacture of EPS patterns

a experimental model for evaluating filling performance of the EPS particles is raised in this paper. With this model

the comparative study on filling effect for several kinds of filling methods is proceeded. Aimed to the special situation of filling methods with single filling gun for the handwork or mechanical moulds

the filling method of pule absorbing with the help of positive pressure is adopted to solve the pattern’s defects with the self made testing device.
