Abstract：

Tree-way tube is broadly applied in the fields of industry,construction and decoration.In order to improve the three-way tube's quality and reduce the production cost,the study of the tree-way tube bulging process is imperative under the situation.The selection of medium is one of the key technologies for bulging process.A large amount of tests were carried out using different materials,such as paraffin,clay,nylon,silastic and daltoflex.From the experiment data,it is concluded that all mediums mentioned above can meet the required bulging coefficient.But for the internal and external quality of the parts and in view of the law of metal flowing,it can be seen that nylon,silastic and daltoflex can be selected as medium for the part of the internal wall with high quality requirement.Contrarily,paraffin can be selected as medium for the part of the internal wall with low quality requirement or without,which can be recycled and reduce cost.This has the important instructing meaning to the actual production of the tree-way tube bulging process.
