Abstract: A manifold-type extrusion sheet mould was designed based on the Pro/E software. In order to get the optimized parameters, an insert "Plastic Advisor"was used to analyze the effect of the manifold shape and the sector size on the flowing state in the mould. It was found that the optimal end diameter of the manifold was XX mm and the optimal fan-shaped area height was 2 mm. These values were agree with those obtained from traditional calculations
