Injection moulding is an efficient means for producing plastic products in large quantities. Warpage deflection is one of the most severe defects occurring to the moulded plastic parts. In this paper, we report a novel method for reducing warpage deflection by applying a Uniform Design of Experiment (UDE) method. UDE is an experimental approach that is able to distribute experiments evenly within experimental space, especially when large number of experimental levels is necessary. We describe the method with a case study, for which the experimental table is developed and the procedure for the application of the method is elaborated. The results demonstrate that the method is effective for reducing injection moulding warpage deflection, and it is relatively more efficient than other means of DOE (Design of Experiment) approaches
