Moldflow software is used to analyze the warping of the PMMA sheet in this article. It is shown that density of bar-defects, cross-section shape of bar-defects and sectional dimension of bar defects influence the warping in different level. The relationship of bar-defects and warping is amply analyzed. As a result, it is found that cross-section shape of bar-defects and sectional dimension of bar defects have more influence to warping, especially in the vertical direction of the surface. At last, some feasible method is put forward to decrease the warping.
