Evaluation of Technological Path and Quality Control System Case Study in Giad Batteries Factory

There is a big industrial growth in Sudan with economical development, so there is a big need for transportation trucks and Vehicles. The batteries are very important part of these vehicles and it's under control of ISO since Sudan is a member of COMESA. SARIA factory had been chosen as field of application of this study, because it is the pioneer and the singlet one in Sudan. Based on the above economical and technical considerations, the goal of thesis is evaluation of the technological path and quality control program that adapted in this factory. This evaluation had been done by the analysis of the technological procedures, and the used of techniques of process capability index Cp and their effect on the design tolerances and then to compare them with the theoretical foundations, Beside using modern computer packages which can be used to inspect and investigate the ratio and the types of the defects and their reasons and how to avoid them. The results and conclusions shows that there are: There are many inspection stations which are necessary are not in charge. The computer program which is designed and applied were effective to get the results and draw charts. Also deviations and defects while preparation and mixing the raw material, as well as for the positive and the negative grids and sheets. All these deviations and defects was evaluated so this indicate many series technical problems and there was detailed analyzing of the reasons and how to treat them, and after treating these technical problems by the new management of the factory, we were able to notes big changing at the percentage of the deviations and defects and positive changing in the values of the production process capability index Cp. Finally a suitable and necessary recommendation is in the end of this thesis.
