An anisotropy study was performed on a constrained thin-walled injection molded component using measurements made from a laser measuring system. Wall thickness and material glass fiber concentration were varied to determine their effects on parallel and perpendicular shrinkage rates. Several ranges of the processing control factors were used in the study. The shrinkages were determined and were described as a function of glass fiber concentration and wall thickness. The shrinkage ratio (a ratio representing the parallel shrinkage rate divided by the correlative perpendicular shrinkage rate) was used to investigate the influence of wall thickness and glass fiber (G.F.) concentration on shrinkage.
