Theory Study and Numerical Analysis of Ultra-Thin Wall Injection Molding

Abstract:

The article focuses on the discussion of size relationship of melt viscosity of ultra-thin wall injection molding, revising the viscosity model of traditional stimulant Cross-WLF. It takes the theory of Uhland wall-slip, trying to analyze the influence which the wall-slip of the molding makes on injection molding. It also points out the limitation of constant heat transfer coefficient in the molding. The change rules of the heat transfer coefficient is among the study. Using the method of numerical simulation and experience, the article verifies the consistency of experience result and the change of the factors, such as using ultra-thin viscosity model, wall-slip and the change of heat transfer coefficient while doing the simulation.
