| Abstract: | Several new techniques for model prediction and improvement of weld-line strength in injection-molded parts were introduced. The theoretical approaches and practical examples based on diffusion and Flory-Huggins theory of the free energy of mixing and BP neural network to predict the weld-line strength were reviewed,and the scopes of application of prediction formulas were given. The mechanism and practical examples of new techniques for improving weld-line strength,avoiding the weld-line or reducing it in ... |
