Abstract

DFMA (Design for manufacture and assembly) method is one of the development fields that can produce high efficiency product by using Boothroyd Dewhurst software. The machinery product for this research is T8 pneumatic pump that are built with plastic material. This product was analyzed by DFMA method to reduce the parts assembly and cycle time with the DFA tool analysis. This project also aims to show the low cost of manufacture in order to obtain the suitable process and material with the DFM tool analysis. Through this analysis, research on the current design and standard dimension for T8 diaphragm pump was done by using Solid Work software. A series of analysis been performed on 4 type of new T8 pump design according to the suggestion of original analysis. Selections of the new improvise design from 4 proposing pump will be done by using the D.O.E technique. From this method each of this pump are categorized by its design and analyzed again by the same DFMA software. Finally, choose the best design of high index efficiency and low time assembly. The related tables and charts can be practically used for comparison on current and improvise pump, the chosen of improvise pump shows 14.8 of index efficiency that more than the original pump which is 7.8. And time for assembly pump are less and quicker for the improvise pump which shows 40% faster than the original pump. For the DFM analysis, term of low cost show that improvised pump was 45% was cheaper than the original T8 pump. And through the DFM tool, polypropylene was the suitable material for manufacturing purpose.
