Industrialisering av konsumentprodukt : Från inkommande material till färdigvarulager

This report examines the industrialization of a newly developed household machine on behalf of Technogarden Engineering Resources in Karlstad, Sweden. The report is a part of the final course in the Bachelor Program in Mechanical Engineering at Karlstad University and takes place in spring 2014. An innovator, an investor and a engineering consultant firm have through collaboration developed a new type of gruel machine. The product is in its final stage of construction and is planned to be manufactured in a production located in Sweden, autumn of 2014. To compete against today’s trend in outsourcing manufacturing to low cost countries for better profitability, the industrialization of the gruel machine must be done with a minimum amount of resources in order to become successful, which also describes the problem of this study. Using pre-study material in form of Lean production literature, visiting a successful production site and gathering data from involved engineers a specification was developed which describes what this industrialization must achieve and which requests can be accomplished. The specification involves the main questions such as capacity in number of gruel machines produced in a certain amount of time, ergonomics and how to achieve equal product quality. A comprehensive product study has been done to identify how the machine is meant to be assembled where the focus was to analyze timing, identifying item groups and assembly sequence. Six concepts on different factory layouts were created using two dimensional sketches of the actual plant chosen for the machine. The sketches show visual layouts of how the production equipment can be physically arranged in order to assemble the machine. The concepts are then assessed according to a valuation schedule in which the main factors are arranged and an engineering assessment is made of how well the different concepts satisfy these factors. From the valuation schedule the concepts obtain a score and the concept with the highest score wins.The winning concept was worked further on by developing a detailed layout using software Google Sketchup. Using the detailed layout a cost-estimation was made on the manufacturing equipment needed. The results of the study show that the gruel machine best is assembled together in a continuous production in form of a line layout. The assembly process is done by operators manually distributed among four stations equipped with materials via rack of items. Two of these layouts are required to meet the market demand at 20 000 gruel machines a year. An exact sizing of commodity and finished inventories could not be determined because of underdetermined suppliers and deliveries
