    Economic and general analysis of quality defects and their solutions of pet gourmet bottles
    (2016) Naseer, Zaeem; Ahmed, Waheed; Awais, Muhammad
    Despite abundant evidence that there are some issues regarding bursting of bottles due to some major factors like quality defects before and after manufacturing, but unfortunately there is presently no major study that focuses on the theme. The main aim of the current thesis is to examine the product and the main reason of neck & base crack issue in the final product. This can be done by analyzing the reaction of different sections & plant of the factory. While focusing on the period between 2015 and 2016 the thesis traces the evolution of the neck & base crack issue dating back to 2010. The thesis also shows how the conditions will affect the quality of raw material & final product. In parallel, the thesis explores the quality defects on preforms & bottles after getting manufactured. This was strongly indicated from the 2010 that this problem will increased and definitely will target the market value and sales. To highlights the main reason of problem, humidity was concluded as the main reason for this issue. The central argument of the thesis, therefore, is effect of humidity on preforms & bottles and the after products. The thesis contends that by controlling the humidity we can control this issue of neck & base crack because it mostly occurs during the humid season from June to September. Getting data from all warehouses & by noticing all the parameters suggested by original equipment manufacturer the data was collected to investigate the reason behind this serious issue. Also, help from the technical team of the original equipment manufacturer was taken. The site visits were arranged so that they can have a brief and comprehension visit of the plants and to find out the main reasons behind the fault. After all the investigation and more than 1 year of hard work, they were all able to come to a conclusion that this problem was occurred, more or less, due to the factor of humidity. Finally, this thesis observes that the main problems lies in controlling the environment on all the plants like injection molding plant where preforms are manufactured & blow mold where bottles and final products are being manufactured and also the warehouses where the final product is kept. Moreover, this thesis also observe the wrong parameters used in manufacturing. After all the investigation, completion of action plans and remedies taken the company was able to reduce the defect to 95% expectedly. This could be a big achievement.
