Evaluation of the quality control system at Khartoum Central Foundry

Abstract

Metal casting industries are actively involved to reduce the scrap rejection and rework during the manufacturing process of the components. To achieve this, the production concerns must follow the quality control procedures correctly and perfectly without any negligence .This research addressed the problem of evaluation of quality control system using 5S method, at Khartoum Central Foundry. The method of analysis and comparison of data obtained from the field study has been used. The Research objectives are: reducing losses from the foundry productive, and improve the work environment using 5S, as well as activating the test lab equipment. Among the most significant findings of this research were: 82% of the defects production was due to the quality of the sand used in the work of casting molds, and also because of the lack of skilled technicians and workers as well as the operating system and the path are identical to the output quality. It is recommend to follow the method of 5S to improve the workplace, and raise production efficiency, and train workers and technicians on modern methods of processing templates, and to avoid mistakes in order to increase production and reduce waste, and also to provide the corresponding specifications of sand, by using the scientific method. A number of venues are proposed for future studies, including: Economic impact in following 5S system in an environment of Labor, and use simulation computerized program in foundries operations to improve the design of casting molds.
