| Abstract: | Metacon B.V. is a company that produces fire doors, rolling shutters and similar products. One product of Metacon is the fire-retardant overhead door. This is a door consisting of several panels guided up and down through a rail. This door is very heavy, which is a major disadvantage. Because of this, the material costs are not only incredibly high, but also causes problems in the production and installation of the door. Metacon has designed a panel that is much lighter called the OHD-ECO. This new design however will have many consequences in production and installation. For this reason, the main question of this design essay will be how the new production process must be organized to produce a cheaper and lighter door. To answer this question different kinds of analysis have been performed. The production and installation of the current overhead door has been investigated, but also the story surrounding the door has been analyzed. All actors have been looked at, as well as the purpose of the product. From these analyses it was concluded that it will be very important for the new production process that it will use as little space in the workshop as possible. Also, the aim should be to minimize the turnaround time as currently, a lot of the time semi-finished products wait days until they are finished. To solve these problems a mobile workstation is designed. At this station the whole production process can be run through. This station not only takes minimal space, but also shortens the turnaround time significantly. An order must be finished before another one can be started on the station. Besides these advantages, the station also has a number of features to further improve the production process. The wooden frame can be easily assembled with the sliding system. Also the profile at the end of the work surface makes sure there will not be any need for measuring and fastening. This profile can also be flipped. With this a person can perform all the actions on a panel single-handed. By doing measurements an estimation of the saved time this station should cause has been made. This estimation resulted in a time saving of 35% in comparison to the production of the current door. With this result the new work station can be regarded as a success. The aim of 25% saved time was easily achieved. The station is also a realistic solution to implement at Metacon and will be able to facilitate the production of the OHDECO sufficiently. A point has to be made that this production process is still hypothetical until the OHD-ECO is approved for production. To achieve this the panels will have to be tested in front of a fire oven. Whether the panels will survive this test remains a question. While waiting for this answer several things can be done to improve the aforementioned results. Firstly it is advised to follow the production of more doors with the current production process. This will lead to more reliable results and more reliable time saving estimation. Also, the weight of the final design of the work station can be reduced. The current design will weigh around 500 kilograms. This makes the work station even without load quite unworkable. |
