Abstract [en]

This thesis describes how a cost reduction project was done on the Packsize ondemand packing machine EM7. The cost reduction was achieved by making minorredesigns of the EM7.The project began by studying the EM7´s structure and function by working on itsassembly line. A short literature study on the subject Design for Manufacturing wasalso done.By working on the assembly line and by speaking with staff from production anddevelopment departments, a number of ideas for reducing manufacturing costs arose.Estimations of the potential cost reduction size for each proposal were done incollaboration with vendors and the purchasing department. Based on the size of the cost reduction, technical risk, impact on the assembly lineand the development time the various proposals were ranked. The two highestranked proposals were selected for further development towards finished solutions.One of the ideas that were selected to develop in to a finished solution meant thatsome of the pneumatic valves were replaced with others. Most of the mechanicalfeatures on the EM7 are operated by pneumatic cylinders, and they are controlled bythe valves. The valves in use today have very fast switching times which makes themrelatively expensive. By replacing the valves with valves that have higher airflow butlonger switch times, costs are reduced through a lower purchase price of the valves.Thanks to the higher airflow this can be done without affecting the EM7´sperformance.The second proposal was selected because it reduces assembly time. By using rivetsfor the assembly of the EM7’s z-fold infeed system, assembly time can be reducedsignificantly.The total cost savings per machine is between 960SEK to 2620SEK depending on theequipment choices.
