Analysis of an assembly process and environmental impact for a new design of food grater

This research analyses and evaluate food grater components in order to reduce the required quantity and to consider the improvement of possible sustainable design based on various material selection, particularly to specific parts. This study will use integration methodology to achieving sustainability which is Design for Manufacturing Assembly (DFMA), and Life Cycle Analysis (LCA). The analysis result will show the reduction of the part numbers from 20 parts to only four parts respectively to the significant alteration for specific components. Furthermore, the Life Cycle Analysis (LCA), the weight is reduced by 12.46 gram after changing the material from PPE to ABS. Also, the carbon footprint effect reduced by 40% while air acidification effect is reduced by 21.9%. Besides the material changes also reduced the total energy consumed by 36.4%. This study found that both methods are capable of reducing production costs assembly time, and consequently can enhance the environmental impact of a product.
