This thesis is to study the possibilities to implement Design for Manufacturing and Assembly methods into K. Hartwall’s product development. This study has been executed as a case study and one of K. Hartwall’s products has been analyzed part by part according to Boothroyd’s methods of DFMA. The goal with these methods is to reduce the number of
components in the final assembly stage to achieve cost savings. DFMA methods does not
take to account the products full lifecycle but only the early stages of development. First
the product was analyzed and then it was modified and redesigned using SolidWorks and then the savings were calculated using Boothroyd’s methods. Lastly the new and old design were compared to see the total cost saving.
After the modification to the product had been done, the total amount of components was
reduced from 116 to 69 components. Most of the removed parts were bolts and nuts that
according to Boothroyd’s methods are the costliest in a final assembly. The list of separate components was also reduced from 37 different components to only 31 different components.
After calculating the time savings of all the modifications, the new design ended up having a 38% shorter production time, theoretically speaking and a theoretical cost reduction of 12.2%. With these results the study can be considered a success and to conclude the results shows that K. Hartwall should continue investigating the value of implementing DFMA methods to their product development stage.
