THE PRODUCTION LINE OF AN ALUMINUM ALLOY WHEEL MANUFACTURING INDUSTRY AND TO IMPROVE THE QUALITY OF PRODUCTION USING QUALITY CONTROL TOOLS

Abstract

As we know that lots of the research is going on to the growth of economy and how we can improve it and in today’s world the growth of automobile industry or growth aluminium alloy wheel manufacturing industry is very high. If we talk about the use of aluminium alloy then the aluminium is very strong material for various application, so we can use the aluminium alloy in the automobile industry/aluminium alloy wheel industry. The objective of this project is to study of the production line of an aluminium alloy wheel manufacturing industry and to improve the quality of production using quality control tools. The defects during the manufacturing process occurs which are responsible for reducing the quality of product are analysed with the help of using technique like historical data analysis , check sheet, pareto diagram, cause –effect diagrams, design of experiments and root cause. The all data is collected for various inspection method. Using check sheet facts has been collected and all of the defects are studied. The result find by this study shows that major defects or reason for rejection of product or component during manufacturing process were shrinkage non- metallic inclusions, micro cavity and gas holes. All defects are studied and the possible cause for defects are shown in Fishbone diagram. The Fishbone diagram may be called as cause defect. Shrinkage mainly occurs due to the lack of accounting error, lack of feed and ineffective inventory. the basic phenomena for lack of feed is that while hydrogen bureaucracy gasoline holes and porosity in aluminium casting , due to the amount of the hydrogen present in molten metal. The hydrogen absorbing capacity of molten metal is due to temperature effect.
