The Design of Damping Block in the Tire Tread Extrusion Die

Abstract:

It is one of the keys that determining reasonable damping block geometry in the process of designing the extrusion dies. In this paper, the finite element software POLYFLOW was used to simulate the flow process of tread rubber in the head channel. In addition, the orthogonal experiment method was adopted for the optimum design of the damping block in the head channel. After optimum design, the flow velocity of rubber melt becomes more uniform in the full width at the head outlet. Consequently, the warping deformation of the rubber, which flow through the head channel, is also significantly reduced.
