Abstract
The critical dimensions of product samples made during a standard certification procedure for an injection molding process are measured and a loss factor value is computed for each such dimension. Using statistical techniques, the largest loss factor value is partitioned into percentages of loss contributed by a predetermined set of loss elements. The loss element contributing the largest percentage is corrected so as to improve the quality of the process and the product. The method provides a way of determining what kinds of process corrections will most effectively improve product and process quality.
