The low productivity levels in the metalworking industry, particularly in casual and small industries, are often attributed to the long times it takes to carry out a changeover, the recurrent machine downtime as well as overexertion of rework tasks. Prior research studies undertaken have shown the usefulness of lean manufacturing tools such as SMED, regular maintenance and formatted work in eliminating such wastages. Hence, this study sought out to solve these issues by looking at the design and application of a new production model in a chrome roller making SME. Some of these included employing SMED, so as to reduce changeover processes; great or increased reliability of equipment through preventive maintenance; and the reduction of operational variability through standardized operating procedures. The results obtained were significant change; a 22.9% reduction in change over time, a 65.4% reduction in rework and a massive 76.4% reduction in machine downtime which resulted into a 30.9% increase in productivity levels. These findings demonstrate the feasibility of the model to be effectively employed for improvement of other business parameters in a company. Further studies that incorporate complex technologies are welcomed, aimed at developing effective and unique solutions for different manufacturing environments.
