Metal Part Cleaning Prototype For SME’s Automotive Industry In THAILAND

บทคัดย่อ

       In an automotive industry, fabricating metal automotive parts requires a painting process as the final step for manufacturing. A jig can be used to hold the parts and handle the position of the automotive workpiece to prevent errors in the painting process. The jig is sprayed repeatedly several times so that it is sprayed over several layers, resulting in excessive paint thickness. As a result, error of the workpiece’s position can affect the color quality of the workpiece. Currently, there are two cleaning methods for paint removal including mechanical process and chemical process. This research examines the equipment design for the paint removal process by using chemical solvent. Next, the prototype is developed to reduce the manufacturing cost of equipment set, in which the performance is equivalent to the conventional version. The result shows that the equipment manufacturing cost can be reduced by 39 percent. This research is expected to be useful for small and medium-sized industrial plants to develop the cleaning equipment set at an affordable cost and to enhance the metal cleaning service in the automotive industry or other industries that need to clean the metal parts in the painting process.
