Evaluation of a Model Describing the Advancing Flow Front in Injection Moulding

Abstract: The simulation of the advancing flow front during mould filling in the injection moulding cycle is important as a way of anticipating manufacturing defects, particularly different types of welds, air traps, cold spots and hot spots. The purpose of the present work was to evaluate a model (the distance model) simulating the advancing flow front and predicting potential issues related to the progression of the flow front such as welds and air traps. The distance model is based on a mathematical theory of Hele-Sh… Show more

“…In this sense the flow mimics that of a Bingham plastic. Moreover, this picture has been verified experimentally by Piscotti et al [29], who have favourably compared solutions to the distance model with injection moulding experiments in which polystyrene (a highly shear-thinning fluid) was injected into an industrial mould. Nevertheless, the injection problem is still worth investigating from the view point of formal asymptotics as there are a number of unresolved questions about the nature of the flow for finite, but large, values of n. These include, for example, how the transition occurs between the regions of 'yielded' flow lying behind the advancing sections of boundary and the 'unyielded' flow elsewhere, questions on the nature of the flow in the immediate vicinity of the injection point and on the magnitude and nature of the flow in the 'unyielded' regions.…”
