Abstract: To improve the green products manufacturing process,a preferred method of process parameters based on coupling spreading orthogonal algorithm was proposed.Taking advantage of orthogonal test in solving single-objective optimization problem,a spreading orthogonal algorithm based on coupling intensity between process parameters was proposed,and offspring was bred with niche evolution to achieve optimized multi-green-objective.The method was applied to the injection molding process parameters design,and the injection molding green design model was constructed by selecting the injection molding process parameters for multiple green indicators and defining the relationship between the mutual coupling intensity.The design of a fan shell was taken as the example to verify the effectiveness of the proposed method.

Key words: coupling intensity, niche evolution, spreading orthogonal test, green design, injection molding process parameters
