| Abstract: | The shape of pp armchair are introduced. The structure of the point gate and hot runner of mould, four sets of cylinders and its operative characteristics were researched. It was described how to control the temperature of hot runner. On the basis of the features of materials, the effects of injecfion pressure, injection speed and temperatures of mould on the articles were emphatically analysed. According to the technical conditions designed to control the operation, the results indicated that the products have no flow mark, flash and other faults. |
