【Abstract】 The steel-plastic profile coextrusion process and its applications were simply introduced. The development of the theoretical fundamentals related to the coextrusion process was reviewed. The available numerical methods for the analysis of polymer extrusion process were compared with each other. The implementation of the numerical simulation technique in this field was also introduced and a new research item related to the optimum control of the process and the mold parameters was put forward. It is pointed out that to carry out the multi-disciplined research work,including the theoretical fundamentals,numerical simulation in combination of material,process,equipment and mold technology,is an important way to solve those problems obstructing the steel-plastic profile coextrusion technology coming to wide applications.更多还原
