Abstract
Taking advantage of a micro powder injection molding production of a critical functional component in a miniaturized mechanism, a method for the formulation of specification intervals was developed, based on the evaluation of the shrinkage. The synthesis allows to allocate tolerance intervals according to a desired risk of rejecting parts in future evaluations.
Such specifications are formulated as a function of the shrinkage, optimizing its impact on different features of size independently of their shapes or dimensions. The method is of general validity for any molding process where the material undergoes a change in dimensions due to a phase transformation.
