| Abstract: | Based on the flowing deformation behavior of plastic melt, the concept of pullingreloading is brought forward. The physical model and mathematical model, which can describe new material melt and old material melt flowing together in hot runners, are established. The influence of parameters, such as injection speed, injection pressure, viscosity, and temperature,to pulling - reloading technology is analyzed. Principle of designing hot runner mould is brought forward. |
