| Abstract: | Based on the study of polymer melt rheology,the influences of variation of the cutting rate on the moulding of plastic parts are discussed.The relations between the cutting rate and the gateforms and sizes of injection moulds are explained.The result of this study has been used to the design of the feeding system of the injection moulds for large plastic parts of automobiles and good results have been gained. |
