摘要：

Using the thermal properties previously acquired for a polystyrene-zirconia suspension, the solidification and shrinkage of injection-moulded rectangular bars was computed by a finite difference numerical method. By considering the final stage of mould packing, upper and lower bounds for the moulding conditions needed to avoid internal shrinkage defects and sink marks were successfully predicted. The resulting computer method allows the influence of a wide range of material and machine parameters to be explored.
