چکیده انگلیسی
This paper investigates a geometric technique for generating flow fronts arising from a point gate, in a bounded cavity, with obstacles-a problem which often requires intensive computations for its solution. The technique is based on the assumption that flow velocity is proportional to the plastic part wall thickness. A complex flow pattern in the cavity of an injection mould is constituted by four types of basic flow patterns, namely absorption, refraction, diffraction and merging. Combining these four flow patterns quickly generates the filling pattern in an injection moulding which is useful in the conceptual design stage during the plastic product development. Although the context of application discussed is in plastic injection moulding, the technique is applicable in numerous areas.
