The customer satisfaction is the basic concept in quality control. So, all manufacturing companies seek to establish a quality system and quality control in all operations to decrease the defective products and avoid customer dissatisfaction. The objectives of this project are to reduce the defects and improve the customer satisfaction and consequently decrease the waste and improve the profitability in a metal and wood industries’ company. This project uses a statistical process control to monitor the behavior of the processes in the production line and define the defects. Analysis of all kind of defects is carried out to find the main causes of these defects. Statistical quality control was applied for every process in the production line and the process capability is calculated. A method to decrease the variability and eliminate the waste in the production line was also applied.

In Medcoplast Co. factory in Egypt founded in the late 1960s that started by only producing simple plastic droppers, nowadays Medcoplast Co. have twelve identical all electrical hot-runner plastic injection molding machines for production of plastic preforms and packaging products with 25% of market share in Egypt and even market shares in northern African countries such as Algeria. The main production in facility is PET-Plastic Preforms. A high exchange & refurbishment time of molds (718 min) occur leading to a lower capacity of production, direct time & money losses, while Single Minute Exchange of Die (SMED) is considered a major lean manufacturing tool & one of the most used techniques to tackle mold exchange operation management & time reduction of them. In this project, Implementation of the basic steps of SMED technique separation of activities led exchange to be reduced by 34% (244 min reduction) including recommendations made regarding operators, inspection approach and material handling. In addition, aiming for standardization and visualization of operation, a quarterly update-able Stream Map has been developed presenting Mold exchange activities flow, assigned operator and cycle times, to facilitate operation on both supervision and operators as a present supporting tool and as guide for future operation improvements, estimating to accumulate at least an extra 7% to the reduction. Any reduction of mold exchange cycle time would directly translate into money & products saved ( ≈ 90,000 - 110,000 preforms for each hour ) as a result of exchange time reduction.

Waste reduction is the most important aspect in the lean production so that the manufacturing companies adopt this tool to improve the productivity in its production lines and improve customer satisfaction. The project’s aim and objective are concerned with improving the productivity in harness production factory by reducing time waste. The factory is facing a problem in time balancing; the operations are not done in equal timing which causes time waste problems in utilization and production rate. This project focuses on analyzing different production line stages as defining exactly the main reasons of time waste. A suitable methodology will be applied such as Simo-chart, Ergonomics, and time analysis for the production line to achieve the balance that will help to reduce the time waste and increase the production rate.
