Abstract: The DFMA technology is an important part for the key technology of concurrent engineering, which runs through the whole process of product development. The DFMA technology has obvious advantages with more and more attention by enterprises. In this paper, based on DFMA theory, in the early design stage of composite molecular pump products, in order to shorten product development cycle, reduce product cost and improve product quality, the manufacturing and assembly of products were analyzed, and we optimized product design by considering various factors such as technicality, technical characteristics and economy. At the same time, the comprehensive evaluation method is adopted to construct the evaluation model and compare the schemes before and after optimization, confirming the rationality and feasibility of the optimization scheme.

Key words: DFMA, molecular pump, product optimization, comprehensive evaluation method
